Hardware prerequisites
The grinding machine must meet additional hardware requirements before any grinding
cycles can be used.
One or two handwheels are required for motion overlay during setup.
There must be connection options for the following external equipment:
● Acoustic emission sensor
● Measurement control
● Touch trigger probe
● 7 rapid inputs via MCPA for:
Call and return conditions
The grinding cycles are programmed independently of the actual axis names. The collions-
free approach to the grinding position is to be done in the higher-level program before the
cycle is called.
The required values for spindle speed and direction of spindle rotation must be programmed
in the part program if there are no defining parameters in the grinding cycle.
The G functions active prior to the cycle call remain active beyond the cycle.
Coordinate systems for grinding
In general, CNC grinding machines have separate coordinate systems for grinding and
dressing. The zero points of both coordinate systems must be defined once when setting up
the machine.
The workpiece zero is defined by the operator when setting up the machine, by scratching
the workpiece in all necessary axes. All additional geometric specifications for creating the
automatic program refer to this zero point.
The dresser zero is defined during setup by scratching the wheel with the dressing
diamonds. It serves as a reference point for the dressing program.
