3 G/M Codes
3 - 51
W( w) : Amount of material to be removed for final cut, Z-axis.
F(f),S(s),T(t): F = feed-rate, S = spindle speed, T = tool selection.
The F, S, and T functions of G73 and previous blocks are applicable to G73, but
all F, S, and T functions from N(ns) to N(nf) are not applicable to G73. They are
only applicable to the fine cut command G70.
Fig. 3-39 Cutting Path of G73 Compound Canned Cycle
Details:
(1) N(ns)~N(nf) define the machining path of A A1 B.
(2) A maximum of 50 blocks can be inserted from N(ns) to N(nf).
(3) No subprogram is available from N(ns) to N(nf).
(4) The tool returns to A when the cycle finishes.
(5) The cutting amount U( i), W( k) and the cutting cycles R(d) are modal codes.
They remain valid until another value is defined.
