Appeal No. 96-1899
Application No. 07/936,007
Figure 8 illustrates the conventional apparatus.
Specification at 7. A numerical control section 1 reads out and
analyzes machining programs which have been previously stored in
storage section 2. Numerical control section 1 determines the
movement quantity of each axis and outputs it to the axis drive
section 7. Axis drive section 7 controls machine tool 8 to
perform a desired machining on the workpiece 16. Axis drive
section 7 converts the axis movement quantity into drive signals
that can cause machine tool 8 to rotate workpiece 16 and move
tool turrets 17 and 18 according to the stored program.
At the same time, numerical control section 1 determines the
current position of each axis shown in Figure 8 for tool turrets
17 and 18. This is done on the basis of the previous axis
position and axis movement quantity. Display section 4 displays
that position data. For each axis name 9, data 10 indicates the
current position.
Concerning the movement instruction to each axis, the arrow
direction is denoted as + and its opposite as -.
For workpiece 16, rotation is to the right (clockwise) for
the “+” instruction and to the left (counter-clockwise) for
the “-” instruction. Specification at 1-3.
