Multi cut threading macro program example using G76

Multi cut threading macro program example using G76

Custom Macro – Using variables for the Programming :

Ideal application for the use of Variable programming (i.e. Custom Macro Programming) on a CNC Lathe :

As such the usage is covering very vast application area. You name it and it can be coded using macros. But, by and large following are the core application areas :

1) Threading applications like variable lead threading, Multi start threading,

Square and Trapezoidal threading, circular form non-standard type

threading ;

2) Multi-start worm cutting ;

3) Face and radial grooving of non-standard type;

4) Design one’ s own cycle of any type.

Example : Carrying out 4 start threading of the size – M16 x 2.0 mm pitch. Write a custom Macro “A” Program for the same. Use Multi-cut threading cycle – G76. Use following data :

Data :

i) O. D. = 15.8 mm
ii) δ1 = 30.0 mm
iii) δ2 = 5.0 mm
iv) 1st cut depth = 0.3 mm
v) Lead = Pitch x no. of starts = 2 x 4…
