Meaning
G1: Linear interpolation
X, Y, Z: Linear axis positions
A, B, C: Rotary axis positions
A2=, B2=, C2=: Angle programming (Euler or RPY angle)
A3=, B3=, C3=: Directional vectors in the X, Y and Z coordinates of the WCS.
A4=, B4=, C4=: Surface normal vectors at the start of the block in the X, Y and Z coordinates
of the WCS.
A5=, B5=, C5=: Surface normal vectors at the end of the block in the X, Y and Z coordinates
of the WCS.
LEAD= : Leading angle
1)
TILT= : Tilt angle
1)
1) The interpretation of the angle indications depend on the setting in MD21094 $MC_ORIPATH_MODE
Further information
5-axis programs are usually generated by CAD/CAM systems and not entered at the control.
So the following explanations are directed mainly at programmers of postprocessors.
