8. Setting Up The Tool Library
Enter the Diameter
Type in a tool description
Select the tool number. This will be identified as tool 1 (M06 T1)

9. Setting Up The Tool Library
Select the type of Tool.
An End Mill has a flat bottom. A center cutting is recommended since plunging is often required.
A Bull Mill has a nose radius on its corners - Define the radius here.

10. Setting Up The Tool Library
A Standard Drill (118° Point)
An engraving tool is a type of tapered cutter.
Define the taper angle.
A Ball Mill has a constant radius (1/2 Diameter) on its end.
Define the diameter at its end point.

11. Setting Up The Tool Library
Station Number – Defines the tool location for Automatic Tool Changers
