Temporary transition to the machine coordinate system (#MCS ON/OFF)

Notice

Not included in the scope of the standard license. The use of this feature requires a license for the "Transformations” extension package.

The MCS functionality temporarily deactivates the active kinematics and/or Cartesian transformation as well as all offsets included in the axes in order to position machine axes directly. After leaving the MCS, the state before selection is restored.

For example, a tool change often requires the approach to a defined tool change position with known machine origin coordinates. Approaching this machine position may pose a problem in the CS since the CS axes are positioned by the NC program.

There are no restrictions in the MCS regarding the usable NC functionality; however, it is not possible to program #RTCP... / #TLC.. , #CS.., #ACS.., #BCS.. and #ECS...

In addition, programmed offsets are only valid in the MCS until they are deselected and are not stored.

When the axis configuration is changed by external axis exchange (e.g. #CALL AX..) in the MCS, it must be noted that a definite axis configuration is required to reactivate kinematic and/or Cartesian transformation.

Programing Example

Temporary transition to the machine axis coordinate system (MCS)

N10 #TRAFO ON

N20 #CS ON[1.5,0,32,14.5,0,45]   (Select a BCS)

N30 G01 G90 F5000

N40 X0 Y0 Z0

N50 #MCS ON EX TOOL   (Transition to machine CS with the option)
                      (‘EX TOOL’ - tool is only included)
                      (with MCS OFF)

N60 T1 D1             ( Tool length is NOT included here,
                      ( but in line N70)

;...

N70 #MCS OFF          (Deactivate MCS; RTCP and CS are)
                      (reactivated)

N100 #TRAFO OFF

N110 #CS OFF

N400 M30
