Helical interpolation is G12 for CW and G13 for CCW.
Requires a position move to start point using polar coordinates.
G0(G1)R_ I_J_A_
G12(G13)A_Z_F_
A is the total number of degrees.
Z is the Absolute Depth of travel.
Cutter comp CANNOT be used.
A range is from 1.0 to 65535.0 degrees.
Helical cannot be transformed.
SPIRAL INTERPOLATION use polar data to achieve a start and end radius that is different. Use same start line but:
G12(G13)R_A_Z_F_
Now you have good data.
