Definition of required values
As an aid for defining the values for the above-mentioned machine data, the following two
sketches show the basic interrelations between the vectors.
Figure 1-14
Meanings of vector designations:
• $MC_TRAFO5_PART_OFFSET_n: po
• $MC_TRAFO5_TOOL_ROT_AX_OFFSET_n: ro
• $MC_TRAFO5_JOINT_OFFSET_n: jo
• $MC_TRAFO5_BASE_TOOL_n: to
Note
For the previous diagram, it has been assumed that the machine has been traversed so that
the tool holding flange is in line with table zero (marked by *). If this cannot be implemented
for geometric reasons, the values for to must be corrected by the deviations.
