7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
547
In circular cutting with an inward offset, the actual feedrate for a specified
feedrate (F) becomes as follows:
F ×
Rc
Rp
Rc: Radius of the path of the cutter’s center
Rp: Programmed radius
As the actual feedrate becomes the value obtained from the above
equation, the specified rate F can be achieved on the program path.

If Rc is too samall in comparison with Rp so that
Rc

≐0, the cutter will
stop. To prevent this, the minimum deceleration ratio (MDR) is set.
When

≐0,
the actural rate becomes as follows:
