Fanuc Face grooving using G74

Fundamentals:-

The cycle G74 stands for longitudinal cutting process. Where we remove material from face ether performing as drilling cycle or face grooving, the cycle is beneficial to cut stubborn materials like stainless steels.
Because of complete material removal motion. In G74 cycle we can cut through along with 'Z' axis as well as 'X' axis, also can use on turnmill operations while drilling off centre drills.

Format of G74:-

________
G74 R
G74 P Q X Z F
________

R- retraction amount.

P- shifting value while cutting along X axis in micron.

Q- Depth of cut in micron.

X- Cutting last destinations along X axis.

Z- Cutting last destinations along Z axis.

F- Feed.


Note:- shifting value 'P' should not exceed the width of grooving tool.

If tool width is 4mm then shifting value should be 3.5mm.


Example:- 

G00 X40.0 Z2.0;

G74 R0.5 (shifting value);

G74 P3500( 3.4 shift value) Q500 (depth of cut) X52.0 Z-7.0 F0.07;

G00 Z10.0

Fanuc grooving cycle G75

Fundamentals This cycle does a peck drilling operation for grooving or drilling perpendicular to the axis. The cycle can actually be used to cut multiple grooves, or (on a machine with a C-axis and live tools) drill multiple radial holes at various positions along the length, The explanation here is restricted to cutting a single groove. Structure ______ G75  R G75  X  P  F _______ R= Retreat amount after each peck, radial distance. X= X coordinate of groove bottom (Diameter to cut).  P= Peck depth, radial distance in micron. F= Feed rate. We can remove material performing single groove same as insert thickness as well as more than that. Example of single groove as insert thickness ________ G00 X54.0 Z-20.0; G75 R0.5; G75 X30.0 P1000 F0.1; G00 X100.0 Z50.0; _____ Example of Groove more than insert thickness Let the groove width is 5mm of the above drowning ________ G00 X54.0 Z-20.0;   (using 3mm insert thickness) G75 R0.5; G75 X30.0 Z-25.0 P1000 Q2500 ...

Fundamentals of G72 Cycle

Introduction to G72 cycle This cycle generates a part shape from a cylindrical raw material, with cuts perpendicular to the axis. The cycle definition has the part shape, depth of cut, finish allowance and couple of other parameters. Fanuc G72 Facing Cycle If you have spent some time on cnc machine with fanuc control in cnc machine workshop, then you might surely have used  G72 Canned Cycle Facing  and cnc turning cycle G71. Because cnc cycle programming in fanuc cnc control is just easy. Why do we use cnc cycles read  pros and cons of cnc programming cycles . In this post I am going to elaborate the use, and programming of the  G72 Canned Cycle Facing  on Fanuc cnc control. Fanuc cnc control is widely used, no doubt one of the most favorite cnc control of cnc programmers, due to its ease of programming and durability. Programming G72 W R G72 P Q U W Parameters First Block Parameter Description W Depth of cut. R Return value after a cut is complete. Second Blo...
