The speed of the tool with respect to the workpiece when the workpiece
is cut is called the cutting speed.
As for the CNC, the cutting speed can be specified by the spindle speed
in rpm unit.
V: Cutting speed
Spindle speed N
<When a workpiece should be machined with a tool 100 mm in
diameter at a cutting speed of 80 m/min. >
The spindle speed is approximately 250 rpm, which is obtained from
N=1000v/πD. Hence the following command is required:
Commands related to the spindle speed are called the spindle speed
function ( See II–10) .
