10.1.5 Deep-hole drilling 1 (CYCLE83)
Function
With the "Deep-hole drilling 1" cycle, the tool is inserted in the workpiece with the programmed
spindle speed and feedrate in several infeed steps until the depth Z1 is reached. You have the
option of entering the following infeed steps.
● Number of infeed steps constant or decreasing (via programmable degression factor)
● Chip breaking without lifting or swarf removal with tool retraction
● Feedrate factor for 1st infeed to reduce the feedrate or increase the feedrate (e.g. if a hole
has already be predrilled)
● Dwell times
● Depth in relation to drill shank of drill tip
Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
Machine manufacturer
Various defined values can be pre-assigned using setting data.
Please refer to the machine manufacturer's specifications.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Approach/retraction during chip breaking
1. The tool moves with G0 to safety clearance of the reference point.
2. The tool drills with the programmed spindle speed and feedrate F = F · FD1 [%] up to the
first infeed depth.
3. Dwell time at drilling depth DTB.
4. The tool is retracted by retraction distance V2 for chip breaking and drills up to the next
infeed depth with programmed feedrate F.
5. Step 4 is repeated until the final drilling depth Z1 is reached.
6. Dwell time at final drilling depth DT.
7. The tool retracts to the retraction plane at rapid traverse.
