Measuring Cycles for Milling and Machining Centers
5.10 CYCLE996 workpiece: Measure kinematics
Tolerance lin (Tolerance value of offset vectors I1 to I4)
The tolerance parameters should enable the user to make a "good" or "bad" assessment
when the kinematics are measured. The prerequisite for this is that kinematics vectors have
already been correctly entered. The tolerance values and the extensive normalizing
associated with them must be specified by the machine manufacturer.
Parameter: _SETV[7]
Tolerance red (Tolerance value of rotary axis vectors V1, V2)
Parameter: _SETV[8]
Effect of the tolerance parameters:
1. Tolerance value = 0 -> no effect
2. Tolerance value <> 0 and tolerance exceeded → Cancel alarm 62430, 62431 with display
If the result bit is active, the fields are displayed in which the tolerance value was found to be
exceeded on comparison of the $TC_CARR parameter and the _OVR result parameter.
Observe the machine manufacturer's instructions!
Protocol file (Protocol file for the calculated kinematics vectors)
Selection:
● No
● yes
● Yes, TRAORI(1);
The protocol file is saved in the current NC data path (or workpiece) in which the
measurement program is running. The file name of the protocol file is generated from the
name of the swivel data record and a counting index:
→ e.g. swivel data name generated from $TC_TCARR[x] = "SWIVEL"
Name of protocol file: "SCHWENK_M1.MPF"
If the file name already exists, M1 is incremented (up to M99). Once there are 99 protocol
files, the process starts again from protocol file "_M1". The user is responsible for all protocol
file operations.
The protocol file contains the syntax of the swivel data record parameters
→ e.g. $TC_CARR1[1]=-426.708853 $TC_CARR2[1]=-855.050806 ... ;I1xyz.
In the settings "Yes, TRAORI(1)", a protocol file with the corresponding TRAORI machine
data is generated.
For coding, see _MVAR

of the 1st value and parameter ($TC_CARR1, etc.) that has been exceeded.
