Fanuc G72 Facing cycle

What is the G72 rough facing cycle?

                   G72 is a G- code that given coded instruction to the machine that we wish to use the rough facing cycle that cuts towards the centreline of the workpiece. We not only turn along with the Z-axis but also turn on the X-axis using the G72 rough facing cycle.

                                In this cycle, the machine tool will cut along with the X-axis towards the centerline of the workpiece. 

Use of G72 Cycle:

                                This cycle is specially used when we have to remove the stock in the face of the workpiece. The G72 cycle format used two lines of G codes that given instruction to the machine tool how to perform.

Format of G72:

G72 Wµd Re;

G72 Pns Qnf Uµu Wµw Ff;

Each command of this two-line are broken down and explained below:  

G72	Facing Cycle
WΔd	Depth of cut in Z-axis
Re	Retraction value
Pns	Counter start block number
Qnf	Counter end block number
UΔu	Finish allowance in X-axis
WΔw	Finish allowance in Z-axis
Ff	Feed rate

                                                                                 

Conclusion:

                     Thank you so much for visiting our blog. It is very useful for a cnc programmer to create a part program for creating a job profile.
