[Program Sequence]
(1) Assume that there are a number of pulleys with a similar contour, shown as above. To simplify
the programs of these pulleys, express the contour of part A using variables.
Variable
Name
PC11
Pitch between the pulley groove
XH1
Height of pulley groove
XD1
Starting point of cutting
ZW1
Width of groove
ZW2
Taper amount of groove in Z-axis direction
TW1
Width of cutting off tool
D1
Value of l of 1R
DK
Value of K of 1R
(2) Program the pulley groove cutting cycle as a subprogram using the variables.
Since this program is called for after execution of axis motion command(s), it is prepared in
incremental mode so that it can be used wherever it is called.
The subprogram file name is "PULL-PTTN1.SUB".
