How does the master calculate the hook tool grinding method for the automatic lathe? Solve. I want to sharpen the knife every month

The calculation method is based on the same grinding method as the ultra-wide and shape forming knives. The knife width cannot be greater than the groove width and can only be smaller than the groove width.

First, the main declination angle at both ends of the knife is 2 -5 degrees,

Secondly; the main declination angle of the cutting edge of the knife must also have an included angle before the main edge can participate in cutting,

Thirdly; do not install the hook tool too low or too high. Friction with the workpiece affects cutting.
