CNC Machining Tutorial-12 (Threading-2):-

Before starting this Tutorial let's first discuss about some different terms and codes for a threading program or threading operation:-

G32 :- Threading Cycle

For more understanding regarding basics of threading and the various terms please go through this--- https://www.mechprof.com/2021/10/cnc-machining-tutorial-10-threading.html 

Problem: we have to work on cylindrical block of 90mm length and 65mm diameter to make the workpiece like as shown in the image (i.e. the thread length should be 80mm ) :- 

The desired product should look like this

Mathematical Calculation & Assuming values:-

Pitch (P) = 3.5mm

Major Dia. = 65mm

L= 80mm

Depth of cut  = 0.6134p = 0.6134*3.5 = 2.1469mm

Minor Dia. = 30-2(2.1469) = 60.7062mm

Solution:- The Code and the machined workpiece is :--
