21.6 Grinding
General
Grinding tools are identified by tool type 400, 410; dressing tools are identified by tool type
490. The "New tool" function offers these types for selection. The tool list shows the "Grinding
disk" and "Dressing tool" tool types listed according to their tool type. To generate the grinding
disk correction, a tool setter creates a dressing program. Depending on the complexity, the
tool setter makes use of external or internal code generators. This program will be assigned
later to a grinding disk.
Oscillation cycles
These grinding cycles permit the machining of workpieces with grinding machines using two
geometry axes.
The machines type does not exist because the cycles create only an oscillating movement
that can be used as required on every machine.
This requires a SINUMERIK control as well as fast inputs/outputs for the program processing.
The cycles package provides the following cycles:
● CYCLE4071: Longitudinal grinding with infeed at the reversal point
● CYCLE4072: Longitudinal grinding with infeed at the reversal point and measurement
control
● CYCLE4073: Longitudinal grinding with continuous infeed
● CYCLE4074: Longitudinal grinding with continuous infeed and measurement control
● CYCLE4075: Surface grinding with infeed at the reversal point
● CYCLE4077: Surface grinding, plunge grinding with measurement control
● CYCLE4078: Surface grinding with continuous infeed
● CYCLE4079: Surface grinding with intermittent infeed
