Clamping And Setting The Tool To The Machine

First, we need to make sure that the knurl rotates freely around the pin. Spread graphite grease if necessary.
Clamp the tool to the turret of the lathe. While the chuck rotates very slowly, approach the tool to the workpiece until the knurl makes contact with the workpiece.
Approach the knurl to the workpiece following the ‘F’ direction up until the teeth plunge a little into it. Check out the resulted print.
The printed width (h) must be equal to the width of the teeth on the knurl. If the width isn’t correct, change the clearance angle.
The tool and the workpiece need to be aligned.
