Enter Your cutting tool geometry starting with Tool Diameter (Turn diameter for Lathe)
All input fields displayed on the screen are important.
Normally when you change the tool type, default data is loaded from the database.
You can override this behavior in the Settings tab on the Fields and Limits that Reset to Default when Tool Type Changes panel by un-checking Reset Tool Data checkbox
Here are the input fields available for Tool Geometry
Tip Dia (Mill, Drill)
Diameter of the cutting end of the end mill, drill, reamer etc
Turn Dia (Lathe)
Diameter of the finished work piece.
When working in CSS and IPR mode it makes sense to keep Turn Dia equal to actual maximum diameter of the workpiece. If you fail to do so, you may overload the spindle by calculating incorrect depth of cut and feedrate
N# of Flutes (Mill, Drill)
Effective number of cutting teeth on your milling or drilling tool.
N# of Inserts (Lathe, Boring Bar)
Effective number of cutting edges that do work at the same time. IE: some boring bars have 2 inserts
The distance from the nose of a tool holder to the tip of the cutting tool.
For integrated or arbor-mounted tooling, use the distance from the spindle nose to the tip of the tool.
Corner Radius of the insert or the tip of the tool
Length of the cutting portion of the tool.
Be careful as some tool types like button cutters do not allow full-depth cuts.
Lead Angle of the cutting edge.
Angle between the cutting edge and a plane perpendicular to the center line of the tool
Common values for end mills
90: regular straight edge
45: Common angle for face cutters
5-30: High feed mills
Lower angles allow increased feed rates
Diameter of the non-cutting portion of the tool
Helical angle of the flutes.
