After the X and Y axis are positioned, the Z axis quickly moves to the R point, and then feeds to the Z point at the speed given by F, then the spindle is oriented and moves a certain distance in the given direction, and then quickly returns to the initial point or the R point. After that, the spindle rotates at the original speed and direction

G85

The canned cycle is very simple, and the execution process is as follows:

X, Y axis positioning, Z axis quickly to point R, feed to point Z at F speed, and return to point R at F speed.

G86

Fixed cycle

Ring (boring)

The execution process of this canned cycle is similar to G81. The difference is that the spindle stops when the tool feeds to the bottom of the hole in G86.

Quickly return to the R point or the initial point and then make the spindle rotate

G87

Fixed cycle (reverse boring)

In the G87 cycle, after the X and Y axes are positioned, the spindle is oriented, and the X and Y axes move in the specified direction by the distance given by the processing parameter Q, and move to the bottom of the hole (point R) at rapid feed rate, and the X and Y axes are restored At the original position, the spindle rotates at the given speed and direction, the Z axis feeds to the point Z at the speed given by F, and then the spindle is oriented again, and the X and Y axes move the distance specified by Q in the specified direction for rapid feed The speed returns to the initial point, the X and Y axes return to the positioning position, and the spindle starts to rotate

Note the same as G76
