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 = 8 mm
vi) Chamfer amount = 1.0 times the lead.
vi) Root diameter = 13.3 mm
vii) Thd. Height = 1.25 mm
viii) Length of threads = 50 mm
ix) No. of finishing passes = 3 nos.
x) Limiting depth of cut per pass = 0.075 mm
xi) Depth of cut for finishing pass = 0.050 mm.
xii) Angle of Approach = 60 degrees.

Plasma-Jet DS 3015 Max 200 Plasma Cutting System

low-wear and low-maintenance gears are designed for continuous operation
optimum bed speed even for fine contours and tight radii
automatic torch height control
adjustable cutting current
stand-alone cutter table features rigid steel construction for high load capacity
stand-alone table eliminates thermal and mechanical influences on the plasma cutter system
quick-coupling for cutter head changes in seconds
minimized tooling time ensure maximum cost savings
magnetic holder of cutter head allows quick change-over from plasma cutting to oxy-fuel flame head cutting
use the existing cutting tables to find the optimum cut
The machine may be customized with an optional oxy-fuel flame head and a cutter table with a maximum table load of 2000 kg/sqm
