Machining Operations
Unit 8 Mirroring (FCL 2 function)
With unit 8 you use check boxes to define the desired mirrored axes.
Unit 10 Rotation (FCL 2 function)
With unit 10, rotation, you define an angle of rotation by which smarT.NC
rotates the subsequently defined operations in the active working plane.
If you define only one mirrored axis, the TNC changes the
machining direction.
Reset mirroring: Define unit 8 without mirrored axes.
Before Cycle 10, at least one tool call must be programmed
including definition of the tool axis so that smarT.NC can find
the plane of rotation.
Reset rotation: Define unit 10 with rotation 0.
