What is the command for turning cycle?
G71 Turning Cycle Overview G71 turning cycle cuts the whole contour repeatedly which is given in P Q blocks. Depth of every cut can be controlled by first-block U value. Second-block U W are the finishing allowances which can be given if you want to make a finish cut with G70 finishing cycle.
What is a G71 cycle?
G71 is our G-Code that lets the controls know that we wish to use a roughing cycle and that the following information applies to that. The U on the first line of code is the depth of cut of each roughing pass.
What is G73 cycle?
When using roughing cycles on a CNC lathe we have a few options. The standard G71 cycle roughs the profile using linear moves along the Z-Axis. The G72 cycle is used for facing and the G73 pattern repeating cycle is used when we are machining a profile that is already cut.
What is G73 in Fanuc?
Fanuc G73 pattern repeating cycle helps cnc machinists to program/maintain/debug rough material removal programs easy. But Fanuc G73 Pattern repeating cycle removes the rough material by taking cuts along the contour. So from the first cut G73 pattern repeating cycle cuts the same shape as the finish component.
What is G70 in CNC?
The G70 Finishing Cycle can be used to finish cut paths that are rough cut with stock removal cycles such as G71, G72 and G73.
What is G98 in G-code?
Fanuc controls provide modal G codes that control where the tool ends up following a cycle. The G98 code causes the tool to return to the initial level after each canned cycle operation; the G99 code causes the tool to return to the R-point level after each canned cycle operation.
What is the purpose of G70 and G71 code?
List of G-codes commonly found on FANUC and similarly designed controls for milling and turning
| Code | Description | Milling ( M ) |
|---|---|---|
| G69 | Turn off coordinate system rotation | M |
| G70 | Fixed cycle, multiple repetitive cycle, for finishing (including contours) | |
| G71 | Fixed cycle, multiple repetitive cycle, for roughing (Z-axis emphasis) |
What is the difference between G73 and G83?
So what’s the difference between G73 and G83? The G73 canned cycle is peck drilling with a short retract or pause for relatively shallow holes, whereas G83 is peck drilling with a full retract for deep holes. Sometimes G73 is referred to as “break chip drilling”, and G83 is referred to as “deep hole drilling”.
What is G41 and G42?
G41 is left compensation and G42 is right compensation. On a CNC machine, it is usually recommended to use climb milling, this needs to be taken into consideration when writing our programs and deciding which direction to apply cutter compensation. When we wish to cancel the compensation, G40 is used to turn it off.
What does G43 mean?
Tool height offset compensation
List of G-codes commonly found on FANUC and similarly designed controls for milling and turning
| Code | Description | Turning ( T ) |
|---|---|---|
| G42 | Tool radius compensation right | T |
| G43 | Tool height offset compensation negative | |
| G44 | Tool height offset compensation positive | |
| G45 | Axis offset single increase |
