Cylindrical grinding

Function
The grinding-by-reciprocating cycle is called for the machining of a cylindrical seat if the
wheel width is smaller than or equal to the width of the seat to be machined.
A acoustic emission sensor 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 measurement control (caliper) which is already in use during the machining can
be used.
For grinding, both wheel types can be used - straight or inclined.
Example for reciprocating
This cycle will be used to machine the cylinder (diameter 200) completely with grinding by
reciprocating using a wheel 70 mm in width.
When grinding by reciprocating, the infeed is to be performed from the left and grinding is to
be performed using the "Exact stop fine" motion behavior.
A acoustic emission sensor and a measurement control are installed on the machine.
Additional specified values:
A_SR=0.5 mm Roughing allowance
A_SL=0.3 mm Finishing allowance
A_FSL=0.2 mm Fine-finishing allowance
SRZ= 0.2 mm Infeed amount for roughing
SLZ=0.1 mm Infeed amount for finishing
FSLZ=0.005 Infeed amount for fine-finishing
N_FR=3 Sparking-out strokes
