G16 is a drilling cycle instruction in KND numerical control system, which is generally used for drilling. The method of use is as follows:
< br >
1. Enter the G16 command, for example, G16.
< br >
2. Define cut-in points and cut-out points, such as X, Y, Z axis coordinates;
< br >
3. Define the drilling depth, such as: F depth or R radius or Q depth;
< br >
4. Define the feed speed, for example: F feed speed.
< br >
For example: If you want to drill a workpiece with a diameter of 10mm and a depth of 20mm, you can use the following procedure:
< br >
G16 G90 G54 X0 Y0 Z0 S2000 M3; (Set initial point and spindle speed)
< br >
G0 Z5; (Quickly move to 5mm away from the workpiece surface)
< br >
G81 R20 Z-20 F200; (Define drilling parameters, R for radius, F for feed speed)
< br >
G0 Z5; (Return to safe position)
< br >
M5; (Close spindle)
< br >
The above is the basic method of using G16 drilling cycle instruction, which needs to be set according to different drilling processing requirements.
Borehole g98g81x_y_z-10r2f1000x indicates the radius of the regression circle. y is the Angle, the right side of the horizontal direction counterclockwise is positive, clockwise is negative g16 and then you have to add g15
