Description |
Possible Values |
Data Types |
Default |
|
mom_alt_pos |
Motion |
The alternate machine tool coordinates (X,Y,Z,fourth axis,fifth axis) for the current goto. This value is different than mom_pos if the kinematics of the machine tool is five axis. Otherwise, mom_alt_pos will be the same as mom_pos. For five axis machine tools, there is always at least two valid solutions when converting the input coordinates (X,Y,Z,I,J,K) into machine tool coordinates (X,Y,Z,A,B). The optimal solution will be mom_pos, the alternate solution will be mom_alt_pos. |
