L976 Calibrating Workpiece Probe On Any Surface (Applicate) - Siemens SINUMERIK 840 User Manual

5 Measuring Cycles for Milling Machines and Machining Centres

5.1.4 L976 Calibrating workpiece probe on any surface (applicate)

5.1.4 L976 Calibrating workpiece probe on any surface
(applicate)
Function and application
The measuring cycle enables the probe to be calibrated in the applicate on any surface,
e.g. at the workpiece, and thus to determine the length.
As from Version 3.5, the length can refer to the probe end (MDC 7004.5=1), otherwise it
refers to the ball centre (see also Section 1.4.3).
The probe is located above the calibration surface by the amount "a" on completion of calibra-
tion.
Precondition:
The probe must be positioned with tool offset and without G53 to face the calibration surface.
The following parameters must be defined prior to call:
Parameters Description
R13 = 0...359.5 Compensation angle position for monodirectional probe (see Section 2.5)
R22 Probe type/probe number (see Section 2.6)
R23 = 3 Calibrating on any surface (applicate) (see Section 2.7.4)
R25 Variable measuring speed in mm/min
R25 = 0 Standard cycle value
R27 = 1...R Number of measurements at same location (typically 1..3)
max
R28 = 1...R Multiplication factor for measurement path "2a"
max
R30 Measuring axis (definition depending on R23)
R31 Axial direction (definition depending on R23)
= 0 Positive axial direction
= 1 Negative axial direction
R32 Set value for calibration
R33 Zero offset range
R36 Safe area
