Cycle run
1 Calculate the proportioning of cuts (infeed).
2 Approach workpiece on paraxial path for first pass from X, Z.
3 Plunge-cut at plunging angle A with reduced feed.
4 Move to contour end point Z2 or X2 or, if programmed, to oblique
contour element defined by W at programmed feed rate.
5 Depending on algebraic sign of P:
„ P>0: Machine contour outline.
„ P<0: Retract at angle of 45°.
6 Return and approach again for next pass.
7 Repeat steps 3 to 5 until X2 or Z2 is reached.
8 Return to starting point on paraxial path.
