Milling Fixed Cycles
Chapter 26
26-31
In the G86 milling fixed cycle, the control moves the axis in the following
manner:
1. The tool rapids to the initial point level a bove the hole location.
2. The cutting tool then rapids to the R point level, slows to the
programmed c utting feedrate and begins the boring operation.
3. The cutting t ool bores at the programmed feedrate until it reaches the
depth of the hole as programmed with the Z--word.
4. If the user has entered a value for the P parameter, the cutting tool
will dwell a fter it reaches the bottom of the hole.
5. The spindle stops rotating.
6. The boring tool is then retracted at a rapid feedrate to the initial point
level, as determined by G98. Spindle rotation continues forward.
When the single block function is active, the control stops axis motion
after steps 1, 2 and 6.
