Multiple repetitive cycles

By using the multiple repetitive cycles, programming steps can be considerably
reduced due to the features that both rough and finish cutting cycles can be execu-
ted by simply defining the finishing shape, and the like.
For the multiple repetitive cycles, seven kinds of cycles (G70 to G76) are provided
In G code systems A and B as indicated in Table 4-2. Note that these G codes are
all non-modal G code.

The same cycles are provided in G code system C. However, different G codes are
used as indicated below.
