4.6 Multiple plunge-cutting – CYCLE411
Function
If the width of the area to be machined is larger than the wheel width, several plunge-cut op-
erations are required. These are performed offset by one wheel width with an appropriate
overlap.
During the individual plunge-cuts, roughing is performed up to the finishing allowance.
A direct-contact vibration pick-up can be used to bridge the distance between the starting
point and the actual workpiece surface within an optimum time by sparking.
To obtain a proper surface on the workpiece, the workpiece is subsequently ground up to its
finished dimension using the reciprocating grinding technology. To check the workpieces for
their finished dimension and to switch the individual feedrates in the various technological
sections, a measuring device (caliper) which is already in use during the machining can be
used.
Straight or inclined wheel types can be used.
