accordance with user specifications so that they correspond to the geometric ratios on the
machine. The only way of setting the ball positions is to reposition the rotary axis that is to be
measured in each case.
Aside from the basic mechanics of the machine, no specific knowledge is required to use
CYCLE996. No dimension drawings or machine location diagrams are necessary to carry out
measuring.
Application range
The Measure kinematics function (CYCLE996) can be used to determine the data that is
relevant to transformations in the case of kinematic transformations that involve rotary axes
(TRAORI, TCARR).
Options:
● Redetermination of swivel data sets
– Commissioning the machine
– Use of swivel-mounted workholders as TCARR
● Checking swivel data sets
– Service following collisions
– Checking the kinematics during the machining process
Kinematics with manual axes (manually adjustable rotary tables, swivel-mounted workholders)
can be measured in the same way as kinematics with NC-controlled rotary axes.
When CYCLE996 is started, a swivel data set with basic data (for kinematics type) must be
parameterized. The measurement itself must be carried out without an active kinematic
transformation.
If, in the setting data SD55740 $MNS_MEA_FUNCTION_MASK bit 7 is set, then depending
on the setting, the kinematics can be measured based on the calculated or on the rotary axis
vectors saved in the swivel data set.
Requirements
The following requirements must be met in order to use CYCLE996 (Measure kinematics):
● SIEMENS measuring cycles package is installed
● Workpiece probe is calibrated
● Calibration ball is mounted
● Oriented tool holder is set up (MD18088 MM_NUM_TOOL_CARRIER > 0)
● The basic geometry of the machine (X, Y, Z) is rectangular and referenced
The right angle refers to the workpiece spindle and should be preferably checked using a
test mandrel.
● Defined position of the rotary axes involved in the transformation
● Defined traverse directions in compliance with the standard of all axes involved in the
transformation according to ISO 841-2001 and/or DIN 66217 (righthand rule)
● Defined size of the protocol file (MD11420 $MN_LEN_PROTOCOL_FILE ≥ 20)
