General prerequisites

Certain preconditions must be met before measuring cycles can be used.
These are detailed in Part 2 Description of Functions (Chapter 8 ff.).
The following checklist is useful for checking which preconditions have been met:
Machine
● All machine axes are designed in accordance with DIN 66217.
● Machine data have been adapted.
Existence of measuring cycles, data blocks
References:
Commissioning Manual SINUMERIK 840D sl base software and HMI sl
Starting position
● The reference points have been approached.
● The starting position can be reached by linear interpolation without collision.
Display functions of the measuring cycles
A HMI/PCU or HMI/TCU is required for showing the measuring result displays and for
measuring cycle support.
Please observe the following when programming:
● Tool radius compensation is deselected before it is called (G40).
● All parameters for the cycle call have been defined beforehand.
● The cycle is called no later than at the 5th program level.
● The system of units allows measuring in the programmed unit system that deviates from
