•How to choose an appropriate diameter tool.
Machine plain surfaces with a larger tool and corner radii with smaller diameter cutters.

How to choose an appropriate diameter tool.


Relation of the cutter diameter and corner R size of work piece
A guide for the smallest possible workpiece radius that can be machined is from 0.6 ─0.7 x diameter of the tool.

* Adjust cutting conditions according to the set up.
* Smaller workpiece corner radii (only >0.5 x cutter φ) may be possible by reducing the width of cut, speed and pick feed.
