Cycle 1053 CONTINOUS CYLIND. GRIND. (#156 / #4-04-1)
ISO programming
G1053
Application
Use infeed cycle 1053 CONTINOUS CYLIND. GRIND. to define the infeed movement of cylindrical grinding and start the infeed. Machining includes reciprocation movements and continuous infeed steps. This means that the infeed is even and performed without interruptions during the reciprocation movements.
Description of function
Reciprocation movement
Combined machining with a reciprocation movement allows you to machine contours that are shorter than the grinding wheel edge. The reciprocation movement is always along the defined contour. The control realizes the reciprocation movement by using the definitions from Cycle 1042 SHORT STROKE DEF. The calculation of the two reversal points for the reciprocating stroke is based on the interpolation position from Cycle 1042.
Infeed movement
The infeed movement is executed radially or axially in the workpiece coordinate system W-CS. Use Cycle 1042 to define the axis to be used for the infeed. SHORT STROKE DEF.
The infeed movement continues until the end position is reached. The end position can be defined based on the interpolation position from Cycle 1042. You can influence the end position by using Q1052 OVERSIZE AT CYCLE END to shift the final end position in the direction opposite to the infeed direction.
By defining multiple infeed cycles with different oversizes, you can create both roughing and finishing operations.
The infeed direction directly affects the parameters to be programmed.
Notes on the program sequence
Cycle 1042 SHORT STROKE DEF. moves the grinding wheel to the starting point.
Positioning behavior in the definition cycles
The infeed movements are performed in Cycle 1053 CONTINOUS CYLIND. GRIND..
Cycle sequence
- The control positions the grinding wheel at the starting position. The control calculates the starting position automatically.
- The cycle starts the reciprocating stroke with Q1001 RECIP. FEED RATE.
- The control preforms the infeed movement continuously until the oversize Q1052 OVERSIZE AT CYCLE END is reached.
- After the last infeed, the control will move the grinding tool up and down along the contour without removing material, until Q1020 SPARK-OUT TIME is reached.
- The grinding wheel leaves the cylinder at Q253 F PRE-POSITIONING to reach the relief amount Q1055.
- Then, the grinding tool moves at rapid traverse to Q260 CLEARANCE HEIGHT or to Q1031 SAFE DIAMETER. The position varies, depending on whether outside or inside machining has been programmed.
Notes
- Use the simulation to check the machining sequence
- This cycle can be executed only in the FUNCTION MODE GRIND machining mode.
- The cycle is CALL-active.
- The infeed direction directly affects the parameters to be programmed.
The following parameters are programmed depending on the infeed direction using X or Z coordinates:

Q1052 Oversize at cycle end? The oversize Q1052 is kept after grinding. This oversize must be smaller than the oversize in Cycle 1042. The oversize is an incremental value. In case of a radial infeed, the oversize refers to the diameter. Input: –99.9999...+99.9999 | |
Q1063 Infeed rate? Feed rate of the infeed movement in mm/min Input: 0...999.999 | |
Q1020 Spark-out time? Time in seconds that the grinding tool follows the contour after the last infeed without material removal. Input: 0...+9999.9 | |
Q1055 Relief amount? Value by which the control retracts the grinding wheel after the reciprocating movement, thus relieving the grinding wheel. This value is incremental. In case of a radial infeed, the value refers to the diameter. Input: 0...10 | |
Q1056 Use encoder? (optional) Selection of an encoder that is active while material is removed and thus monitors the machining operation. 0: No encoder active >0: The machine manufacturer defines the function of this parameter. Refer to your machine manual. Input: 0...99 | |
Q1057 Use acoustic-emission sensor? (optional) Selection of an acoustic-emission sensor 0: No acoustic-emission sensor active >0: The machine manufacturer defines the function of this parameter. Refer to your machine manual. Input: 0...99 | |
Q1064 Feed rate with sensor? (optional) Feed rate of the tool in mm/min when approaching the workpiece while the AE sensor is active. This parameter is effective only while the AE sensor is active Q1057>0. Input: 0...999.9999 |
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.
