Cycle 1016 DRESSING OF CUP WHEEL (#156 / #4-04-1)
ISO programming
G1016
Application
Refer to your machine manual.
This function must be enabled and adapted by the machine manufacturer.
Use Cycle 1016 DRESSING OF CUP WHEEL to dress the face side of a cup wheel. The activated grinding wheel edge is used as the reference point.
Depending on the strategy, the control causes movements based on the wheel geometry. If the dressing strategy in Q1016 was set to 1 or 2, the return of the tool to the starting point is not along the grinding wheel, but via a retract path.
If the Pull-and-Push strategy has been selected in dressing mode, the control will apply radius compensation. If the Reciprocating strategy has been selected in dressing mode, the control will not apply radius compensation.
This cycle supports the following grinding wheel edges:
Grinding pin | Special grinding pin | Cup wheel |
---|---|---|
not supported | not supported | 2, 6 |
Notes
- Activate the FUNCTION DRESS dressing mode only in the Program Run operating mode or in Single Block mode
- Before starting FUNCTION DRESS BEGIN, position the grinding wheel near the dressing tool
- Once you have activated FUNCTION DRESS BEGIN, use exclusively cycles from HEIDENHAIN or from your machine manufacturer
- In case the NC program is aborted or in case of a power interruption, check the traverse directions of the axes
- If necessary, program a kinematic switch-over
- Before starting FUNCTION DRESS BEGIN, position the grinding wheel near the dressing tool
- Make sure there is no risk of collision
- Slowly prove-out the NC program
- Make sure to program a dressing tool clearance angle greater than or equal to 0° relative to the front face of the cup wheel
- Carefully prove-out the NC program
- You can execute this cycle in the following operating modes: FUNCTION MODE MILL, FUNCTION MODE TURN, FUNCTION MODE GRIND and FUNCTION DRESS.
- Cycle 1016 is DEF-active.
- No coordinate transformations are allowed in dressing mode.
- The control does not graphically depict the dressing operation.
- If you program a COUNTER FOR DRESSING Q1022, the control executes the dressing procedure only after reaching the defined counter in the tool table. The control saves the DRESS-N-D and DRESS-N-D-ACT counters for every grinding wheel.
- The control saves the counter in the tool table. Its effect is global.
- To enable dressing of the entire cutting edge, it is extended by twice the cutting-edge radius (2 x RS) of the dressing tool. Here, the minimum permissible radius (R_MIN) of the grinding wheel must not be undershot, otherwise the control interrupts the operation with an error message.
- In this cycle, the radius of the tool shank is not monitored.
- This cycle can be run only in dressing mode. The machine manufacturer may already have programmed the switch-over in the cycle sequence.
Notes on programming
- This cycle is permitted only for use with the cup wheel tool type. If you defined a different tool type, the control will display an error message.
- The strategy in Q1016 = 0 (Reciprocating) is only possible for a straight front face angle (HWA = 0).

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 | |
Q1016 Dressing strategy (0-2)? Definition of the traversing movement during dressing: 0: Reciprocating; dressing occurs in both directions 1: Pulling: Dressing occurs along the grinding wheel solely towards the active wheel edge. 2: Pushing: Dressing occurs along the grinding wheel solely away from the active wheel edge. Input: 0, 1, 2 | |
Q1019 Number of dressing infeeds? (optional) Number of infeeds of the dressing process Input: 1...999 | |
Q1020 Number of idle strokes? (optional) Number of times the dressing tool moves along the grinding wheel without removing material after the most recent infeed. Input: 0...99 | |
Q253 Feed rate for pre-positioning? (optional) Traversing speed of the tool in mm/min for approach, withdrawal, and retraction movements This input value is optional. If it is not programmed, then FMAX applies. Input: 0...99999.9999 or FMAX, FAUTO, PREDEF | |
Q1022 Dressing after number of calls? (optional) 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: Factor for cutting speed not used >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.
Change the following contents as needed:
- Tools
- Cutting parameters
- Feed rates
- Clearance height or safe position
- Machine-specific positions (e.g., with M91)
- Paths of program calls
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.
