Glossary

Effective wheel width
Wheel width of the inclined grinding wheel which is used to machine the diameter. It is de-
pendent upon:
● the physical width
● the evading height
● the angle of the wheel
Evasion/evasion angle
Tapering of the left or right side of the grinding wheel for face-grinding operations in which a
so-called cross-grinding is produced.
GAP/structure-borne noise/air grinding
Bridging the air gap between the workpiece and grinding wheel with a structure-borne noise
microphone, which is built into the machine.
GWPS
Grinding wheel peripheral speed in m/s
MCPA
Input card for rapid I/O to the control system
MD
Machine data; machine data are predefined variables (system variables), with which the
NCK, as per the requirements of the machine manufacturer, is adapted to the machine-tool.
SD
Setting data are system variables that indicate the current machine properties to the NCK.
Unlike machine data, changes to setting data always become effective immediately.
