Cycle 461 TS CALIBRATION OF TOOL LENGTH (#17 / #1-05-1)
ISO programming
G461
Application
Machine
Refer to your machine manual.
Before starting the calibration cycle, you must set the preset in the spindle axis so that Z=0 on the machine table; you must also pre-position the touch probe above the calibration ring.
A measuring log is created automatically during calibration. The log file is named TCHPRAUTO.html. This file is stored in the same location as the original file. The measuring log can be displayed in the browser on the control. If an NC program uses more than one cycle to calibrate the touch probe, TCHPRAUTO.html will contain all the measuring logs.
Cycle sequence
- The control orients the touch probe to the angle CAL_ANG specified in the touch probe table (only if your touch probe can be oriented).
- The control probes from the current position in the negative spindle axis direction at the probing feed rate (column F from the touch probe table).
- The control then retracts the touch probe at rapid traverse (column FMAX from the touch probe table) to the starting position.
Notes
Machine
HEIDENHAIN guarantees the proper operation of the touch probe cycles only in conjunction with HEIDENHAIN touch probes.
Notice
Danger of collision!
When running touch probe cycles 400 to 499, all cycles for coordinate transformation must be inactive. There is a danger of collision!
- The following cycles must not be activated before a touch probe cycle: Cycle 7 DATUM SHIFT, Cycle 8 MIRRORING, Cycle 10 ROTATION, Cycle 11 SCALING FACTOR, and Cycle 26 AXIS-SPECIFIC SCALING.
- Reset any coordinate transformations beforehand.
- This cycle can only be executed in the FUNCTION MODE MILL and FUNCTION MODE TURN machining modes.
- The effective length of the touch probe is always referenced to the tool reference point. The tool reference point is often on the spindle nose, the face of the spindle. The machine manufacturer may also place the tool reference point at a different point.
- A measuring log is created automatically during calibration. The log file is named TCHPRAUTO.html.
Note on programming
- Before defining this cycle, you must have programmed a tool call to define the touch probe axis.
