7.14 Constant grinding wheel peripheral speed (GWPSON, GWPSOF)
Function
With the function "Constant grinding wheel peripheral speed" (=GWPS), you can set the
grinding wheel speed such that, taking account of the current radius, the grinding wheel
peripheral speed remains constant.
Programming

Parameters
GWPSON(T No.) Select constant grinding wheel peripheral speed (GWPS)
It is only necessary to specify the T number if the tool with
this T number is not active.
GWPSOF(T No.) Deselect GWPS; it is only necessary to specify the T number if
the tool with this T number is not active.

GWPS Peripheral speed value in m/s or ft/s
The GWPS can only be selected for grinding tools (types 400-
499).
Example of grinding tools with constant grinding wheel peripheral speed
A constant grinding wheel peripheral speed is to be used for grinding tools T1 and T5.
T1 is the active tool.
N20 T1 D1 ;Select T1 and D1
N25 S1=1000 M1=3 ;1000 rpm for spindle 1
N30 S2=1500 M2=3 ;1500 rpm for spindle 2
…
N40 GWPSON ;Selection of GWPS for active tool
N45 S1 = 60 ;Set GWPS for active tool to 60 m/s
…
N50 GWPSON(5) ;GWPS selection for tool 5 (2nd spindle)
N55 S2 = 40 ;Set GWPS for spindle 2 to 40 m/s
…
N60 GWPSOF ;Deactivate GWPS for active tool
N65 GWPSOF(5) ;Switch off GWPS for tool 5 (spindle 2)
