The entire machining depth amounts to 39mm. When the infeed depth
is a maximum of 5mm, 8 roughing cuts must be made. These are
carried out with a constant infeed of 4.875mm.
Finishing allowance
A finishing allowance for the roughing operation is specified by means
of parameters U
and U
x
finishing machining mode, therefore they are not displayed in the input
screen.
The roughing cuts are always made down as far as these finishing
allowances. After every paraxial roughing operation, the residual
corner produced is immediately removed to obviate the need for a
special residual corner cutting operation on completion of roughing. If
no finishing allowances are programmed, then the workpiece is rough
cut down to the final contour.
