The coordinate systems shown on the right of the figure above are the ZX
plane coordinate systems of tool posts 1 and 2. For clarity, the coordinate
systems are shifted;actually, the origins of the coordinate systems must
match the machine zero points.
Assume the machine configuration shown above. Assume also that offset
number 02 is assigned to tool post 1, and offset number 15 is assigned to
tool post 2.
Suppose that the figure represents the state of reference point return
operation completed with all axes (X1,Z1, X2, Z2). Then set –800
mm(diameter) and –200 mm in parameter Nos. 8151 and 8152,
The positional relationship of the two tool posts matches type (4)
indicated in Section 21.3.2. So set parameters TY0 and TY1 (No.8140#0,
#1) as follows:
Parameter TY1 (No.8140#1)=1
Parameter TY0 (No.8140#0)=1
Then set tool shape data (interference forbidden area) for each tool post.
