Programming example 2

Orientation of an oblique workpiece surface for remachining using CYCLE800
Initial state
• The workpiece is clamped on the swivel
• The swivel table is in its home position.
• The probe is in inserted as T9 and
• The scratch function is used to define the
Exercise
Remachining will be performed with G57 active. The workpiece should be aligned so that for
G17, the tool is located vertically on the previously inclined surface, the workpiece zero
(G57) is the left-hand corner and the workpiece edges run in parallel to axes X and Y (G57).
CYCLE978 should be used to set the 3 edges. To determine the angle, CYCLE998 (1 and 2
angle measurement).
