In-process Dresser

This Parameter:
(paramacro system parameter)
Range: Indicates:
* DRESSER AMOUNT PER REV
(paramacro #5505)
the amount the dresser is to feed into the grinding wheel for each
revolution of the grinding wheel. When the in-process dresser is
active, this amount of infeed is subtracted from the “Current Wheel
Diameter” at each wheel revolution. This is actually the dresser axis
feedrate (in feed per rev) when it is dressing the wheel. 0 to 9.9999999 [inch]
0 to 0.000000 [mm]
* DRESSER RETRACT DISTANCE
(paramacro #5506)
the distance the dresser roll should retract away from the grinding
wheel when the in-process dresser is deactivated. When in-process
dressing is re-activated, the dresser roll automatically performs a
retract return equal to the amount of the dresser retract distance. If the
dresser is not currently retracted when the in-process dresser is
enabled, the control does not perform the retract return (as is the case
when after a dresser calibration operation). The dresser retract or
retract return can also be performed on request when in the dresser
hold state. Both of these moves are performed on the dresser axis. 0 to 999.9999 [inch]
0 to 99999.999 [mm]
* DRESSER SURF SPEED RATIO
(paramacro #5507)
the ratio of the wheel’s surface speed to the roll dresser surface
speed. A ratio of 1.00 would rotate the dresser and the wheel at the
same relative surface speed. A ratio of 0.50 would rotate the dresser
at one half the surface speed of the wheel. A ratio of 1.50 would
rotate the dresser at one and one-half times the surface speed of the
wheel. Surface speed of the wheel is controlled through your part
program and CSS. Surface speed of the roll dresser is controlled
through PAL and calculated from the “Dresser Roll Diameter”,
“Dresser Surface Speed Ratio”, and the current surface speed of the
grinding wheel. The sign of this parameter indicates the direction that
the dresser will rotate relative to the grinding wheel: “+” equals the
same direction and “--” equals the opposite direction. 0 to 99999.00
* This parameter can be configured by the operator on this screen. Other parameters are assigned by the control or PAL during calibration or dressing.
Entering In-process Dresser Parameters
This section covers entering parameter values into the in-process dresser
table manually. You can also enter values in this table through
programming with paramacro system parameters (#5500-#5509). See
chapter 20 for details on assigning values to system parameters.
