Machining start position
This is automatically calculated using the turret turning
position and tool mounting position. To change this value,
note the following conditions.
The path of approach or escape varies with the relation
between the work position and machining start position. In
simultaneous two axis movement, approach or escape is
performed ad shown in Fig. A unless no interference
between a work and tool exists. If interference with a work
exists, the tool bypasses the work as shown in Fig. B.
