MOVEMENTS :
After positioning along the X and Y axes, rapid traverse is
performed to point R. Drilling is performed from point R to point
Z.
The tool is then retracted in rapid traverse.
After inputting the necessary data, by pushing INSERT, pop-up
window is closed and inputted data are displayed in a program window
as the following ISO code program.
1.1.2 Drilling Cycle (With Dwell) (G82)
This cycle is used for normal drilling. Cutting feed is performed to the
bottom of the hole. At the bottom, a dwell is performed, then the tool is
retracted in rapid traverse.
This cycle is used to drill holes more accurately with respect to depth.
By pushing [DWELL], the following items are displayed.
