M1: Kinematic transformation
7.4 TRAANG (option)
MD24996 $MC_TRACON_CHAIN_2[0] = 2 input variables in TRACON
MD24996 $MC_TRACON_CHAIN_2[1] = 3 input variables in TRACON
MD24996 $MC_TRACON_CHAIN_2[2] = 0 input variables in TRACON
MD24996 $MC_TRACON_CHAIN_2[3] = 0 input variables in TRACON
Angle of inclined axis
TRAANG_ANGLE_m
The following machine data is used to inform the control system of the angle which exists
between a machine axis and the inclined axis in degrees:
MD24700 $MC_TRAANG_ANGLE_m
MD24700 $MC_TRAANG_ANGLE_m = angle between a Cartesian axis and the associated
inclined machine axis in degrees. The angle is counted positively in the clockwise direction
(see figure "Machine with inclined infeed axis", angle α).
In this case, "m" is substituted by the number of the TRAANG transformation declared in the
transformation data blocks – m may not be greater than 2.
Permissible angular range
The permissible angular range is:
-90° < TRAANG_ANGLE_m < 0°
0° < TRAANG_ANGLE_m < 90°
No transformation is required for 0°.
For +/- 90° the inclined axis is parallel to the second linear axis.
Position of tool zero
TRAANG_BASE_TOOL_m
The following machine data is used to inform the control of the position of the tool zero point
in relation to the origin of the coordinate system declared for the inclined axis function:
MD24710 $MC_TRAANG_BASE_TOOL_m
The machine data has three components for the three axes of the Cartesian coordinate
system.
Zero is entered as default.
The corrections are not converted when the angle is changed.
