With cycle 1018 RECESSING WITH DRESSING ROLL, you can dress the outside diameter of a grinding wheel via recessing with dressing role. Depending on the dressing strategy, the control executes one or more recessing movements.
This cycle supports the following wheel edges:
Grinding pin | Special grinding pin | Cup wheel |
---|---|---|
1, 2, 5, 6 | not supported | not supported |
The control calculates the number or required recesses based on the width of the grinding wheel, the width of the dressing roll and the value of the parameter RECESSING OVERLAP Q510.

---|---|
Q1013 Dressing amount? Value used by the control for the dressing infeed. Input: 0...9.9999 | |
Q1018 Feed rate for dressing? Feed rate during the dressing procedure Input: 0...99999 | |
Q1027 dressing strategy (0-1)? Strategy during recessing with a dressing roll: 0: Recessing; the control executes a linear recessing movement. The grinding wheel width is less than the width of the dressing roll. 1: Multiple recessing; the control executes linear recessing movements. After infeeding to the dressing value, the control moves the dressing tool in the Z axis in the dressing kinematic model and infeeds again. The width of the grinding wheel is greater than the width of the dressing roll. Input: 0, 1 | |
Q1025 Distance for pre-positioning? Distance between the grinding wheel and the dressing role during pre-positioning Input: 0...9.9999 | |
Q253 Feed rate for pre-positioning? Traversing speed of the tool in mm/min. while approaching the pre-position Input: 0...99999.9999 or FMAX, FAUTO, PREDEF | |
Q211 Dwell time / 1/min? Revolutions of the grinding wheel at the end of the recessing cut. Input: 0...999.99 | |
Q1028 Offset of centers? Offset of the dressing roll center relative to the grinding wheel center. This offset takes effect in the Z axis of the dressing kinematic model. This value has an incremental effect. If Q1027 = 1, then the control does not use a center offset. Input: -999.999...+999.999 | |
Q510 Overlap factor for recess width? With factor Q510, you influence the offset of the dressing roll in the Z axis of the dressing kinematic model. The control multiplies the factor with the value CUTWIDTH and offsets the dressing roll between the infeed runs by the calculated value. 1: For every infeed run, the control recesses with the complete width of the dressing role. Q510 takes effect only with Q1027=1. Input: 0.001...1 | |
Q1026 Wear on dressing tool? Factor of the dressing value in order to define the wear on the dressing roll: 0: The full dressing value is removed on the grinding wheel. >0: The factor is multiplied by the dressing value. The control takes the calculated value into account and assumes that this value will be lost during dressing due to wear on the dressing roll. The remaining dressing value is dressed on the grinding wheel. Input: 0...+0.99 | |
Q1022 Dressing after number of calls? Number of cycle definitions after which the control performs the dressing process. Every cycle definition increments the counter DRESS-N-D-ACT of the grinding wheel in the tool manager. 0: The control dresses the grinding wheel during every cycle definition in the NC program. >0: The control dresses the grinding wheel after this number of cycle definitions. Input: 0...99 | |
Q330 Tool number or tool name? (optional) Number or name of the dressing tool. You can apply the tool directly from the tool table via selection in the action bar. -1: Dressing tool has been activated prior to the dressing cycle Input: –1...99999.9 | |
Q1011 Factor for cutting speed? (optional, depends on the machine manufacturer) Factor by which the control changes the cutting speed for the dressing tool. The control handles the cutting speed of the grinding wheel. 0: Parameter not programmed. >0: If the value is positive, then the dressing tool turns with the grinding wheel at the point of contact (opposite direction of rotation relative to grinding wheel). <0: If the value is negative, then the dressing tool turns against the grinding wheel (same direction of rotation of the grinding wheel). Input: -99.999...99.999 |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
