What is G70 Code 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 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 G72 in CNC?
G72 is our G-Code that tells the machine that we wish to use the roughing facing cycle that cuts towards the centreline of the part. The ‘W’ on the first line is the depth of cut in Z-axis. The’ R’ refers to the distance that the tool pulls off of the material when moving in rapid to the next starting point.
What is G71 in G-Code?
F – FEED RATE. 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 P and Q in CNC?
P = Depth of thread. Q = Depth of first pass.
What is Q in CNC programming?
Q = Minimum cutting depth. R = Finishing allowance. X = Minor Diameter of the thread. Z = End position of the thread. P = Depth of thread.
What is F200 in CNC?
0 F200; The G71 roughing cycle follows the contour that is programmed between the N numbers. It is used to remove material by cutting along the Z-axis leaving some material on for a finishing cut using a G70 cycle.
What is G91 in CNC?
The G91 command switches to incremental (or relative) rather than absolute positioning (Source: Simplify3D) On the other hand, G91 is used to toggle to incremental positioning, also known as relative positioning. Incremental positioning means that your machine tool moves to a location relative to its current position.
What is the meaning of G 42?
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.
