This section provides examples using CSS in typical surface and
cylindrical grinding applications. Before programming any of these
examples, verify that the conditions listed apply to your machine.
CSS While Grinding Part (surface grinding application)
Example 12.19 shows how the wheel spindle speed changes with CSS
active to compensate for a changed wheel diameter. The following
conditions are assumed for this example:
the S--word for this machine applies to the grinding wheel spindle
the grinding wheel spindle has been selected as the CSS axis
constant K is 318.31 (metric constant)
the maximum wheel spindle speed is 9,000 rpm
