Constant grinding wheel peripheral speed (GWPSON, GWPSOF)

The "Constant grinding wheel peripheral speed (GWPS)" function is used to set the grinding
wheel speed so that, taking account of the current radius, the grinding wheel peripheral speed
remains constant.
Syntax
GWPSON(<t no.>)
GWPSOF(<t no.>)
S.../S<n>=...
Meaning
GWPSON:
GWPSOF:
<t no.>:
S...:
S<n>=...:
Note
A grinding wheel peripheral speed can only be programmed for grinding tools (types 400 to
499).
Example
A constant grinding wheel peripheral speed is to be used for grinding tools T1 and T5.

Comment
; Reference axis for G96/G961/G962 is X.
; Constant cutting rate ON at 10 mm/min.
; Face cutting in X at 1.5 mm/revolution.
; Reference axis for G96 is Y,
reduction of spindle speed (Y30).
; Face cutting in Y at 1.2 mm/revolution.
