Angle between the side-cutting edge and the projected side of the tool shank or holder, which leads the cutting tool into the workpiece.

The cutting tool moves across the workpiece linearly, taking chips off the workpiece with each pass. Number of passes depends on the number of threads per inch (tpi), workpiece material and its hardness.

Tangential velocity on the surface of the tool or workpiece at the cutting interface. The formula for cutting speed (sfm) is tool diameter 5 0.26 5 spindle speed (rpm). The formula for feed per tooth (fpt) is table feed (ipm)/number of flutes/spindle speed (rpm). The formula for spindle speed (rpm) is cutting speed (sfm) 5 3.82/tool diameter. The formula for table feed (ipm) is feed per tooth (ftp) 5 number of tool flutes 5 spindle speed (rpm).

A relatively new addition to the Australian market is the Harvey range of machines. This tablesaw currently sells for $3949 and is the mid-range model of three cabinet saws from this stable and has a golden titanium nitride (TiN) tabletop. There is also a plain cast iron table version of this model which sells for $3499. Anatomically, at first glance, this is just another saw, but upon closer inspection there are a number of features that could make this one stand out from the crowd for some users.

The machine runs quietly, does not have a blade brake and there is convenient access to the inside of the cabinet via a hinged door.

The supplied mitre gauge is definitely worthy of mention. It has adjustable expansion slots to ensure a good fit in the track, is very solidly made, rotates smoothly and has preset detentes at zero, 90, 22.5, 45 and 60°. Included is an aluminium flip-stop that has three threaded indexing locations for the brass stop. This locks positively on the fence which extends telescopically, and there is an inbuilt micro-adjust with 0.02mm definition. The mitre gauge alone would likely make this saw stand out for some buyers.

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.

Independent (selected) machining parameters for threading are: workpiece diameter, number of threads per inch, number of starts, and the cutting speed. Dependent (calculated) parameters are: pitch, spindle speed, linear speed of the cutting tool, thread lead angle, cutting time per pass, and total cutting time.

To be competitive, you have to create a screw thread at the maximum linear speed of the cutting tool (ipm). Since the linear speed of the cutting tool is directly proportional to the cutting speed (sfm), you have to know what the maximum cutting speed would be for a given workpiece material and its hardness. Information on the cutting speed data can be obtained from the cutting tool manufacturers.

With a 10amp/230V/50Hz motor, a power rating of 1.65kW (2.2hp) that runs at 3850rpm, accessible and clearly presented on/off switch and smooth, lockable arbor controls for blade height and tilt, this machine will run a 10" (254mm) blade to fairly standard parameters. Careful blade selection may be required for deeper cuts in dense hardwoods. The use of a thin kerf blade will avoid taxing the motor too heavily.

The overhead guard is well thought out, made from clear acrylic for good visibility, with good anti-kickback cauls and overhead dust collection that pipes direct to the main 100mm port on the cabinet, negating the need for an additional hose. All of this can be easily removed for blade and riving knife changes and comes mounted on a rigid overhead boom that keeps the whole assembly up and out of the way of the stock being cut.

Process of both external (e.g., thread milling) and internal (e.g., tapping, thread milling) cutting, turning and rolling of threads into particular material. Standardized specifications are available to determine the desired results of the threading process. Numerous thread-series designations are written for specific applications. Threading often is performed on a lathe. Specifications such as thread height are critical in determining the strength of the threads. The material used is taken into consideration in determining the expected results of any particular application for that threaded piece. In external threading, a calculated depth is required as well as a particular angle to the cut. To perform internal threading, the exact diameter to bore the hole is critical before threading. The threads are distinguished from one another by the amount of tolerance and/or allowance that is specified. See turning.

The rip fence is a solid T-square arrangement with a high-low extrusion that locks solidly. One feature that I really liked is the separate cursors for setting the rip width, whether cutting on the high or low fence configuration. Tooling changes are easy with the arbor lock and the long spanner that is supplied. The arbor has two indexing pins similar to European machines for positive registration, but these can be recessed to allow for aftermarket blades to be used on the machine.

Threading is the process of creating a screw thread. More screw threads are produced each year than any other machine components.

It's not necessary to be "a rocket scientist" to use this calculator. Minimum system requirements: Windows 2000 or higher, Microsoft Excel 2000 or higher, CD-ROM Drive.

Both table inserts lock solidly into place and have levelling grub screws, but they also have custom access holes for the mechanism to change the riving knife (there is an accessory low-profile riving knife supplied), so those who like to make their own zero-clearance inserts will need to account for this.

Edmund Isakov, Ph.D., developed a threading calculator, which is functioning in Excel formulas. It includes major (computational) sheet and two sheets containing cutting speed data recommended by Sandvik Coromant.

This machine, equipped with the appropriate tooling, would be a solid and accurate servant to any home-based or smaller cabinetry shop. Machine supplied and set up by Gregory Machinery in Brisbane.
