[h3]How do I choose a tap size?[/h3]
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.
[h3]How is drill size calculated?[/h3]
Tap-drill diameter equals nominal diameter minus thread pitch. For example, drill size for a 3/8-16 thread is 0.375 0.0625 (pitch) = 0.312 in. in diameter, and for a 10-32 thread, the drill diameter is 0.190 0.032 = 0.159 in. (a #21 drill).
[h3]What factors affect cutting speed?[/h3]
There are many factors that determine the cutting speed, which can be summarized as follows:
(1) Tool Material. Determining the cutting amount can effectively improve the machining quality and output. ...
(2) Workpiece Material. ...
(3) Tool Life. ...
(4) Cutting Depth And Cutting Amount. ...
(5) The Shape Of The Tool. ...
(6) Use Of Coolant.
[h3]Which material has highest cutting speed?[/h3]
Typical cutting speeds: 30 - 310 m/min. The hardest known substance is diamond. Although single crystal diamond has been used as a tool, they are brittle and need to be mounted at the correct crystal orientation to obtain optimal tool life.
[h3]How do you convert GPM to LPM?[/h3]
1 GPM equals how many LPM? 1 GPM equals circa 3.79 LPM, where GPM meaning is gallons per minute, and LPM means liters per minute. To convert US gallons to liters, multiply by 3.78541.
[h3]How do I calculate chip size?[/h3]
Calculation are as follows: Chip Load = Feed Rate (inches per minute) / (RPM x number of flutes). Example: Chip Load = 500 inches per minutes / (15,000 RPM x 2 flutes) Chip Load = . 017″. Chip loads are based on material thickness of average size for cutting edge length of tool.
[h3]Does depth of cut affect chip load?[/h3]

This chip load increases or decreases. It requires more or less forced to share the material beingMore
[h3]What is rubbing in machining?[/h3]
Rubbing: When You're Feeding too Slowly. Most newcomers to machining are shocked to learn they can ruin a tool quickly by feeding it too slowly. Somewhere along the way you may have heard that feeding too slowly causes “rubbing” which is what destroys the tool.
[h3]What is slab milling?[/h3]
Peripheral milling (slab milling) - the surface being machined is parallel to the (often helical) cutting teeth in the periphery of the tool. End milling - fluted cutting edges are arranged on the circumference and end of a rotating shaft that is vertical to the workpiece.
[h3]What is depth per pass in CNC?[/h3]
Depth per pass is a cut setting that dictates how deeply your machine carves down into your material on each pass. Unless you use the Easel Pro feature "Add Depth," you can only set the overall depth as the thickness of your material, which you can set in the “Material Dimensions” section in the upper right corner.
