4. Formed Material Rough Cutting Cycle, G73
Functions and Purposes:
To save machining time, G73 is used to cut a work-piece that has been machined in a
rough cut, forging or casting process and formed with a shape similar to the
finished-product.
Format:
G73 U( i)___ W( k)___ R(d)___
G73 P(ns)___ Q(nf)___ U( u)___ W( w)___ F(f)___ S(s)___ T(t)___
N(ns)
N(nf)
G00 X__ Z__ ;Tool move back
Txxxx ;Change tool (fine cutting)
G00 X__ Z__ ;Move to the start position of Canned Cycle
G70 P(ns) Q(nf) --- ;Fine cutting
Parameters:
U( i) : Cutting amount on X-axis. (radius programming)
If not defined, the parameter "G73 Total Cutting Amount " is used.
W( k) : Cutting amount on Z-axis.
If not defined, the parameter "G73 Total Cutting Amount" is used.
R(d) : Rough Cutting Cycles
I.e. times of cuts required to reach the defined cutting depth on X and
Z-axes. If not defined, the parameter "G73 Cutting Cycles" is used.
P(ns) : The first block number of a fine cut cycle.
Q(nf) : The last block number of a fine cut cycle.
U( u) : Amount of material to be removed for fine cut, X-axis.
