VARIOUS FUNCTIONS AND
PRECAUTIONS OF Symbolic FAPT
1. VARIOUS FUNCTIONS OF
The interference check between tool shape and machining shape or
between tool path and machining shape is strengthened in Symbolic
A pocket may be produced, depending upon parts figure and tool figure
as illustrated above. In such a case, designate the area to cut such a pocket
only by using a reversible tool.
For actual operations, refer to item 3.4.7 of chapter III.
A function of checking the interference of tool and blank in approach and
return relief movement during cutting process of workpieces is provided.
The interference is basically examined according to whether the straight
line connecting from the present position to the next position intersects
the blank or not during the approach or return relief movement.
For cutting the area (B) in the above figure, convexed part (A) must be
avoided, otherwise the interference occurs. Accordingly, the return relief
movement is done to the position were a clearance margin is added to the
blank as illustrated.
