The curve segment milling technology also opens up production options. For example, undercuts, freeform surfaces and variable setting angles can be reliably created. In addition, complex contours can be pre-finished and finished, even on narrow inside radii.

Recently, Thinbit/Kaiser Tool Co. has developed a trepanning-type tool based on the static, lathe, face-grooving inserts it has offered for many years to enable single-point cutting of grooves on a machining center. Called Mill A Groove, this line of tools installs in a user’s boring head to enable a range of groove diameters — with a symmetrical profile or not — to be created.

The CurveMax has a special geometry that permits bigger path distances and line jumps during pre-finishing and finishing. Although the working radius is larger than that of a traditional full-radius mill, the tool still has the same diameter, which leads to a reduction in process times. The larger engagement width means the cutting edge does not suffer from wear at any point. Combined with the extremely smooth, high-performance VaroCon coating, this helps to increase the tool’s service life. The larger and flatter overlap reduces roughness and ensures surface finishes even better than those created by traditional full-radius mills. Inovatools offers the CSC-CurveMax mills in conical and tangential form as four-edged cutters for finishing in different sizes and radii.

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. Agenda: Introduction The power of high-speed printing Know the process The practical side

Here is an alternative to standard end milling — an operation performed on a CNC milling machine to produce circular grooves in the part face. This new single-point trepanning tooling strategy can produce both symmetrical and asymmetrical face grooves, too, and perform fly cutting.

The Mill A Groove can also be used to perform face milling as a single-point, fly-cutting operation. This can be advantageous for applications in which minimal machining witness marks are desirable. For example, using a 1-inch end mill to face a surface wider than that will leave behind multiple 1-inch rows of witness marks. Setting up a Mill A Groove tool in a boring head with a diameter bigger than the part width and performing a fly-milling operation leaves a more uniform surface finish.

Mr. King says compared to end milling, this tool offers advantages such as better groove concentricity and surface finish. It can also eliminate the need to take a milled part to a lathe for a secondary face-grooving operation. In addition, tests have shown that the tool can produce grooves as much as 90% faster than machining with an end mill. The Mill A Groove produced a 0.125-inch-wide face groove in steel in 18 seconds versus three minutes with an end mill. Cut data for the Mill A Groove is determined by simply converting the speeds and feeds used in a lathe face-grooving operation to a single-point milling operation.

Mack Tool and Engineering used modified inserts to create micro-grooves, but they were prone to breaking. After switching to Thinbit Groove ‘N Turn tools from Kaiser Tool, the company experienced increased tool life.

Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

Though most frequently used for diameter measurements, an air plug and platen can be readily configured to measure perpendicularity.

Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.

Manufacturers continue to feel the pressure to reduce costs, increase efficiencies and meet their sustainability strategies.

Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

Working closely with customers and making careful investments has enabled this Wisconsin machine shop to tackle difficult jobs with tight deadlines as a core part of its business.

Until recently, shops had two options to machine circular grooves in the face of a part. One is to spin a part in a turning center and feed in a static face-grooving tool. The other is to use a machine tool to circle-interpolate using an end mill. Shops typically go with the latter option when the part cannot be chucked in a turning center, has a geometry that includes bosses or features impeding tool access, or would create an out-of-balance condition when spun. However, tool breakage and long cycle times can be an issue, especially when using small-diameter end mills. Plus, those tools create only symmetrical groove profiles.

Testing shows that understanding the interplay among cutting speed, tool wear and cutting power can lead to more informed evaluation of metalworking fluids and more predictable machining.

The compact universal head enables better accessibility between the tool and the workpiece, as well as improved surface-finish quality, greater motion range and high-efficiency machining under ideal machining conditions.

Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
