Brazed-tip tools use a body of inexpensive material and a tip or blank of more costly cutting material brazed to the cutting point. Tip materials include high-speed steel, carbides and cubic boron nitride. These tools are available in sizes A though G, with offset point styles A, B, E, F and G all available as either right- or left-hand cutting tools. For square shanks, the number after the letter designation indicates the height or width of the tool in sixteenths of an inch. For rectangular shanked tools, the first number is the total eighths of an inch of shank width, and the second number is the total of fourths of an inch of shank height.

After achieving the appropriate level of power, productivity improves alongside increases to depth of cut, feed rate and speed.

ModuleWorks and Toolpath announce a technology partnership that intends to utilize intelligent cloud-based manufacturing solutions for machining estimation and CAM automation.

I cut a total of six slots in the threaded rod. I used two hex nuts jammed against each other on the threaded rod to guide how much to turn it by to space the slots. Spacing four slots evenly would have been more tricky unless I found a square nut to fit on the threaded rod (or I suppose, I could have jammed a square piece of wood between the two nuts as a guide)

You can use metal thread taps for wood just fine, but I wanted to experiment with making my own from a piece of threaded rod. I started by making a "jig" to hold the threaded rod for grinding slots in it. But before cutting slots in the threaded rod, I cut a slight taper in the end of it. That way the thread will be cut over the course of several turns instead of just by the very tip. I then used my jig to clamp the threaded rod in the vise. The jig itself serves as a guide for a cut-off disk in an angle grinder to cut the slots in the threaded rod. I cut a total of six slots in the threaded rod. I used two hex nuts jammed against each other on the threaded rod to guide how much to turn it by to space the slots. Spacing four slots evenly would have been more tricky unless I found a square nut to fit on the threaded rod (or I suppose, I could have jammed a square piece of wood between the two nuts as a guide) I ground three flat spots onto the other end of the threaded rod to make it easier to grab it in a drill chuck. Again, I used two-nuts as a visual guide to help me space the three flat spots evenly. Home made thread tap next to a proper metal thread tap. The metal one works just fine in wood (and metal). Interestingly, the metal tap is slightly bigger than the one I made. When threading holes in metal, the hole needs to be slightly bigger than the bolt or threaded rod that screws into it, or it will get stuck. With wood, having a hole slightly smaller is not a problem because the wood has some flexibility. That's how wood screws engage. The homemade tap cuts the thread with just the first few turns so it can cut threads closer to the bottom of a blind hole. I could just make another one with no taper at all to cut threads all the way to the bottom of a hole. That's the nice thing about homemade tools — infinitely customizable. Testing it out. Worked well. Though, in retrospect, I should have cut the flutes slightly larger because they had a tendency to get filled with sawdust. Drilling a larger hole before tapping would also help. It was easy to screw a threaded rod into the resulting hole just by turning it with my fingers. Then trying the same method with a wood bolt, which has much coarser threads. I cut wider flutes in this one so I didn't have to back it out half-way to clear the chips. I figure this could be a handy alternative to using a machine screw and threaded insert for some adjustment knob or fastening knob on a homemade machine. With so much wood between the threads, it's very unlikely that the threads would wear out. I did a quick wear test, screwing the screw in and out many times while pushing hard against the drill. Then I had the idea of setting it up to use the screw to lift my table saw. Again, up and down many times, no sign of wear. I figure these coarse threads could be handy for something where a cover needs to be held in place. If I make wooden knobs for the wood bolts, that will make for a cheap and easy way to make threaded knobs to hold a cover onto something. I am using a piece of oak here. Soft woods like pine or spruce would not hold up as well. See also: I bought the improved Jimmy Diresta ice pick.... 20 years ago!

Depth of cut is the simplest of these to increase, but improvements are possible only when there is enough material and power for it. Doubling depth of cut doubles productivity at no increase to cutting temperature, tensile strength or cutting force per cubic inch or centimeter removed (also called the specific cutting force). It doubles the required power, but so long as the tool meets tangential cutting force requirements, there is no decrease in tool life.

Side rake angles are formed between the face of the insert and the line perpendicular to the workpiece when viewing the end. These angles are positive when they slope away from the cutting edge, neutral when they are perpendicular to the cutting edge, and negative when they slope upward. The possible thickness of the tool depends on the side rake angle, with smaller angles allowing for thicker tools that increase strength but require higher cutting forces. Larger angles produce thinner chips and reduce cutting force requirements, but past a maximum recommended angle, the cutting edge weakens and heat transfer diminishes.

The nose radius of brazed-tip tools is related to the shank size, and operators should take care to match tool size to finish requirements.

Determining whether to use high-density fixtures or to simplify workholding requires a deeper look into the details of your parts and processes.

Sufficient relief and clearance angles are both necessary on the end and the side for the tool to enter the cut. Without clearance, chip formation cannot occur, but without adequate relief, the cutter will rub and produce heat. Single-point turning tools also require end and side clearance angles to enter the cut.

Turning is the process of using lathes to remove material from the outer diameter of a rotating workpiece. Single-point tools shear metal from the workpiece in (ideally) short, distinct, easily recyclable chips.

Insert wear is a common indicator of success or failure for any turning operation. Other common indicators include unacceptable chips and workpiece or machine problems. Generally, operators should index their inserts at 0.030” (0.77 mm) flank wear. For finishing operations, operators should perform indexing at 0.015” (0.38 mm) or sooner.

Facing increasing competition from lower-cost imports, Suburban Tool made a move toward large-scale, in-house machining. By identifying a niche in large, precision angle plates and tombstones, the company has strengthened its ability to control quality and protect its reputation.

P inserts are the ISO standard for turning tools, and force the insert against the pocket walls with a pivoted lever that tilts as the adjustment screw is seated. These inserts are best for negative rake inserts with holes in medium to heavy turning operations, but they do not prohibit the insert from lifting during the cut.

Adding pallet systems brought Mach Machine success and additional productivity. The shop has since furthered its automation goals while adding new capabilities.

JD Machine, 2024’s Top Shops Honoree in Human Resources, embodies its “Education for Life” core value with a robust apprenticeship program and significant continuous improvement efforts.

Surface finish in a turning operation depends on the rigidity of the tool, machine and workpiece. Once rigidity is assured, the relationship between the machine feed (in./rev or mm./rev) and the nose contour of the insert or cutting tool can be used to determine the workpiece’s surface finish. The nose contour is expressed as a radius — up to a certain point, a larger radius translates to better surface finish, but too large of a radius can introduce chatter. For machining operations where a smaller-than-optimum radius is required, feed rate may need to be reduced for the desired finish.

Recommended lead angles to control vibrations in boring are between 0 degrees and 15 degrees (in the imperial system. In the metric system, this would be 90 degrees to 75 degrees). At a lead angle of 15 degrees, radial cutting forces are almost twice as high than at a 0-degree lead angle.

Determining whether to use high-density fixtures or to simplify workholding requires a deeper look into the details of your parts and processes.

Compared to depth of cut and feed rate changes, increasing cutting speed is ill-advised. Speed increases lead to significant increases in cutting temperature and lower both tangential and specific cutting forces. Doubling the cutting speed requires additional power while reducing tool life by over half. The actual load on the top rake face can lower, but the higher cutting temperatures can still cause cratering.

C inserts utilize a top clamp for inserts that do not have a center hole. This system relies entirely on friction and is best with positive rake inserts in medium to light turning, as well as boring operations.

As the demand for faster production cycles continues to grow, the ability to produce high-quality parts quickly and efficiently has become increasingly important. High-speed 3D printing has emerged as a key solution to reduce lead times and increase productivity across industries. However, like any advanced technology, it comes with its own set of challenges. In this webinar, Forward AM will explore both the opportunities and hurdles of adopting high-speed printing with a particular focus on overcoming those challenges. It’ll start by discussing the fundamentals of high-speed 3D printing and how it differs from conventional 3D printing methods. It’ll then move on to the key factors that influence successful implementation, including the impact of materials, equipment and design considerations. One of the main hurdles in high-speed 3D printing is ensuring the right balance between speed and part quality. Different materials behave differently under high-speed conditions — and not all equipment is optimized for this process. Forward AM will showcase some validated materials and equipment that are proven to perform well under these conditions. In addition, the presenters will look at real-world examples and applications where high-speed 3D printing has been successfully implemented, highlighting the collaboration between designers, engineers and manufacturers. By the end of this webinar, you'll not only have a clearer understanding of high-speed 3D printing with FFF but also the practical steps and considerations needed to make the most of this cutting-edge technology.

Positive rake angle cutting tools are preferable for most boring operations in order to reduce cutting forces. However, the smaller clearance angles of positive rake angle tools require operators to plan for the possibility of contact between the tool and the workpiece. It is especially important to ensure an adequate clearance angle when boring small diameter holes.

Coordinate systems tell a CNC machine where to position the cutting tool during the program’s execution for any purpose that requires the cutting tool to move.

The eighth and ninth sections also differ between imperial and metric systems. For imperial systems, section 8 refers to insert size, while section 9 covers surface and tool length. The insert size is determined by the size of an inscribed circle in increments of eighths of an inch. The surface and tool length are letter-based, with A-G for the sizes of qualified back and end tools and M-U (with no O or Q) for qualified front and end tools. In the metric system, section 8 refers to the tool length, and section 9 refers to insert size. Tool length representation is letter-based, while for insert size, rectangular and parallelogram shapes use a number to indicate the length of the longest cutting edge in millimeters, disregarding decimals and preceding one-digit numbers with a zero. Other shapes use side length (diameter for round inserts) in millimeters, also disregarding decimals and preceding one-digit numbers with a zero.

I figure this could be a handy alternative to using a machine screw and threaded insert for some adjustment knob or fastening knob on a homemade machine. With so much wood between the threads, it's very unlikely that the threads would wear out.

Radial and tangential forces in boring operations increase as the nose radius increases, but these forces are also subject to the lead angle. The depth of cut of boring operations can alter this relationship: if the depth of cut is greater than or equal to the nose radius, lead angle determines the radial forces. If the depth of cut is less than the nose radius, the cutting depth itself increases the radial forces. This problem makes it especially important operators use a nose radius smaller than the cutting depth.

The first letter in the system indicates the insert clamping method. Four common types dominate, but they each encompass several variants.

The sixth and seventh sections differ between imperial and metric measurement systems. In the imperial system, these sections correspond to a two-digit number indicating the holder cross-section. For square shanks the number shows the total number of sixteenths of width and height (5/8" being where the changeover happens from “0x” to “xx”), while rectangular holders use the first digit to represent the eighths of width and the second digit for quarters of height. There are several exceptions to this system, such as toolholders 1¼" × 1½", which use the designation 91. The metric system uses two-digit numbers to represent the millimeters for both height and width (in that order). So, a rectangular insert 15 mm in height and 5 mm in width would have a number of 1505.

Rigidity is also paramount to productivity in boring. The diameter of the hole and the need for additional chip removal clearance directly influence the maximum size of the boring bar. Practical overhang for steel boring bars is four times their shank diameter. Exceeding this limit compromises the metal removal rate due to loss of rigidity and increased vibration possibility.

How can shops can make informed decisions using data-driven feedback to improve shopfloor efficiency and profitability? And how will these technologies differ between high- and low-volume production?

Radial and axial cutting forces in boring are influenced by the lead angle. The increased axial force of a small lead angle can be especially useful in reducing vibration. As the lead angle increases, radial forces increase and raise the forces perpendicular to the direction of the cut, contributing to vibration.

Diameter, material modulus of elasticity, length and load on the beam influence rigidity and deflection, with diameter providing the largest effect and length the second-largest. Increasing the bar diameter or shortening length will notably increase rigidity.

Top rake angle (also called back rake angle) is the angle formed between the angle of inclination of the insert and the line perpendicular to the workpiece when viewing the tool from the side, front to back. Top rake is positive when it slopes downward from the cutting point and into the shank, neutral when the line from the top of the insert is parallel with the top of the shank, and negative when it slopes upward from the cutting point and above the shank. Inserts and toolholders are also categorized as positive or negative. Positive inserts have angled sides and mount into toolholders with positive top and side rake angles. Negative inserts have square sides relative to the top face of the insert and mount into toolholders with negative top and side rake angles. Top rake angle is unique in that it is dependent on the geometry of the insert — a positive ground or a molded chipbreaker can change the effective top rake angle from negative to positive. Top rake angles also tend to be greater with softer and more ductile workpiece materials, which require high positive shearing angles, while harder and tougher materials are best cut with neutral or negative geometries.

Testing it out. Worked well. Though, in retrospect, I should have cut the flutes slightly larger because they had a tendency to get filled with sawdust. Drilling a larger hole before tapping would also help. It was easy to screw a threaded rod into the resulting hole just by turning it with my fingers. Then trying the same method with a wood bolt, which has much coarser threads. I cut wider flutes in this one so I didn't have to back it out half-way to clear the chips. I figure this could be a handy alternative to using a machine screw and threaded insert for some adjustment knob or fastening knob on a homemade machine. With so much wood between the threads, it's very unlikely that the threads would wear out. I did a quick wear test, screwing the screw in and out many times while pushing hard against the drill. Then I had the idea of setting it up to use the screw to lift my table saw. Again, up and down many times, no sign of wear. I figure these coarse threads could be handy for something where a cover needs to be held in place.

The Automated Shop Conference (TASC) will give shops of all sizes and production volumes key insights and practical guidance on how to implement automation.

Turning subjects workpieces to tangential, radial and axial cutting forces. Tangential force has the greatest effect on power consumption; axial (feed) force exerts pressure through the part in a longitudinal direction; and radial (depth of cut) force tends to push the workpiece and toolbar apart. “Cutting force” is the sum of all three of these forces. With a zero-degree lead angle, they have a ratio of 4:2:1 (tangential : axial : radial). As the lead angle increases, the axial force shrinks and the radial cutting force grows.

Early turning tools were solid, rectangular pieces of high-speed steel with rake and clearance angles on one end. When the tool dulled, machinists would sharpen it on a pedestal grinder for reuse. High-speed steel tools are still common on older turning machines, but carbide has become more popular, especially in brazed single-point form. Carbide sports better wear resistance and hardness, leading to better productivity and tool life, but it is more expensive and requires expertise to resharpen.

Cutting tools’ effectiveness depends largely on the tool’s angle in relation to the workpiece. The terms defined in this section reference inserts to define cutting and relief angles, but can also apply to brazed single-point tools.

S inserts use a simple torx or allen head screw, but require counterbores or countersinks. The screws can seize with intense heat, so this system is best for light to medium turning operations and boring operations.

Soraluce’s wide range of machine heads and the ability to have multiple heads on a single machine (with automatic changing stations) provides flexibility and reduced setups for large-format machining.

Located below the end cutting edge, the end relief angle forms between the end face of the insert and a line perpendicular to the base of the toolholder. Tip overhang can make the end clearance angle (which is formed by the end face of the toolholder and a line perpendicular to the base of the toolholder) larger than the relief angle.

The metal one works just fine in wood (and metal). Interestingly, the metal tap is slightly bigger than the one I made. When threading holes in metal, the hole needs to be slightly bigger than the bolt or threaded rod that screws into it, or it will get stuck. With wood, having a hole slightly smaller is not a problem because the wood has some flexibility. That's how wood screws engage. The homemade tap cuts the thread with just the first few turns so it can cut threads closer to the bottom of a blind hole. I could just make another one with no taper at all to cut threads all the way to the bottom of a hole. That's the nice thing about homemade tools — infinitely customizable. Testing it out. Worked well. Though, in retrospect, I should have cut the flutes slightly larger because they had a tendency to get filled with sawdust. Drilling a larger hole before tapping would also help.

The lead angle (also called the side cutting edge angle or the attack angle) forms between the insert side cutting edge and the side of the tool shank. The angle leads the tool into the workpiece, and enlarging it produces wider, thinner chips. The geometry of the workpiece and the material condition are primary considerations when selecting the lead angle for a cutting tool. For example, tools with emphasized lead angles enable respectable productivity rates when cutting through scale, interruptions or hardened surfaces, without subjecting the cutting tool edge to severe shock. Operators must balance this benefit against increased part deflection and vibration, as larger lead angles create higher radial forces. Zero-degree lead angle turning tools produce chips equal in width to the turning operation’s cutting depth, while lead angle cutting tools make the effective cutting depth and corresponding chip width exceed the actual cutting depth on the workpiece. Most turning operations are efficiently performed within a lead angle range of 10 to 30 degrees (metric systems invert the angle from 90 degrees, making the ideal lead angle range 80 to 60 degrees).

Fourth is a letter to indicate the holder rake angle or insert clearance angle. For rake angles, P is a positive rake where the sum of the end clearance angle and wedge angle is less than 90 degrees, N is for a negative rake where the sum of these angles is greater than 90 degrees, and O is for neutral rakes where the sum is exactly 90 degrees. Exact clearance angles are indicated with one of several letters.

The second section uses a letter to refer to the insert shape. The third section uses a letter to refer to the combination of straight or offset shank and lead angle.

Toolholder style, nose radius and insert shape also have profound impacts on the potential maximum effective cutting edge length of turning inserts. Certain insert radius and toolholder combinations may require dimensional compensation to make full use of this cutting edge.

Feed rate is also relatively simple to alter. Doubling the feed rate makes chips twice as thick, and increases (but does not double) tangential cutting force, cutting temperature and required power. This change lowers tool life, but does not halve it. Specific cutting force (the cutting force in relation to the amount of material removed) also decreases with increased feed rate. The additional force imposed on the cutting edge with increased feed rates can result in the cratering of the top rake insert surface due to the increased temperature and friction generated during the cut. Operators must monitor this variable carefully to avoid catastrophic failure where the chip becomes stronger than the insert.

Feed rate requirements vary depending on the operation’s purpose. In roughing, for example, high feeds are generally better for maximizing metal removal rates, but require high part rigidity and machine power. Finish turning, meanwhile, might slow down the feed rate to produce the surface finish specified on the part blueprint.

Turning uses a lathe to remove material from the outside of a rotating workpiece, while boring does the same from the inside of a rotating workpiece.

Spanning 113,500 square feet, the facility will centralize the company’s storage and distribution, as well as enhance operational efficiency.

Turning is a combination of linear (tool) and rotational (workpiece) movement. Thus, cutting speed is defined as the rotational distance (recorded as sfm — surface feet per minute — or smm — square meters per minute — traveled in one minute by a point on the part surface). Feed rate (recorded in inches or millimeters per revolution) is the linear distance that the tool travels along or across a workpiece surface. Feed is also sometimes expressed as the linear distance the tool travels in a single minute (in./min or mm/min).
