Dwell time.

G10

Programmable Offset Setting or offset value setting.

1. Fanuc G10 G-Code for CNC Machine Programmable Offset Setting

On a cnc lathe machine we do two types of offset setting. Tool Offset Setting and Workshift Setting. With G10 we can do both functions.

Workshift Value Setting or Machine Zero Offset Setting with Fanuc G10

This version of Fanuc G10 is used to set the workshift value. P00 means that we want to set the workshift value. The x-axis value is normally set to 0, the value for z-axis is the distance from the machine zero point to workpiece zero point (this distance is called workshift value or zero offset).

N10 G10 P00 X0 Z200

Tool Wear with Fanuc G10

This version of the Fanuc G10 code is a bit tricky, the value with P is the tool for which we want to make changes. This G10 code adds the given value to the tool wear offset .

N10 G10 P1 U0.02 W0.02

Tool Offset Setting or Tool Geometry Offsetting with Fanuc G10

This version of G10 sets the Tool Offset Setting. If you want to set the tool offset setting value for tool number 8 then you will add 10000 and the value will be (10000 + 8 = 10008), now put that value with P. For G10 x and z values put the tool value in x and z.

2. CNC Programming Example with Fanuc G71 Rough Turning Cycle and G70
3. Fanuc G70 G71 Rough and Finish Turning Cycle Program Example

Here is another cnc programming example, this cnc programming example shows the use of G71 Canned Cycle and G70 for Fanuc CNC Control.

Although I already have posted about the G71 Turning Canned Cycle(Rough Turning Cycle), but that blog post just illustrates the use of G71 and G71 parameters.

This cnc programming example shows a complete contour cutting with G71 and finish cut on contour with G70.

G70 finishing cycle for fanuc cnc control can also be used with G72 Facing cycle for fanuc control. Usage of G70 Finishing cycle with G72 Facing cycle is same as shows here in the following example.

G-code G76 is a cnc cycle which is used for thread cutting on cnc machines.

Threading cycle G76 is explained here G76 Thread Cycle.

Taper thread cutting with G76 thread cycle is explained here G76 Tapered Threading

For Multi-start thread cutting with G76 see G76 Multi-Start Threading

For G76 threading cycle one line see G76 One-Line Format.

G76 threading cycle can be used for internal threading on cnc lathe machines.

This G76 threading example actually cuts external threads on two different diameters.
