CANNED CYCLES OF THE EDITOR<br />

4.5 Bore milling.<br />

Canned cycles (·M· model)<br />

This cycle may be used to increase the diameter of a hole through a helical movement of<br />

the tool. Besides this, if the tool allows it, it is also possible to mill a hole without having to<br />

drill it first.<br />

Geometric parameters:<br />

Machining direction.<br />

Bottom milling.<br />

X, Y Machining point.<br />

Z Part surface coordinate.<br />

Zs Safety plane coordinate.<br />

P Total depth.<br />

Machining parameters:<br />

Defines the direction of the helical drilling path.<br />

It defines whether the bottom of the hole (blind hole) is milled or not (through hole).<br />

Dp Part surface approach distance.<br />

The editor will only show this data if the user has configured the editor to allow it. If this option<br />

is not enabled, the cycle assumes an approach distance of 1 mm.<br />

φ Hole diameter.<br />

φK Pre-hole diameter.<br />

Starting with a hole previously drilled, this parameter defines the diameter of that hole. If not<br />

programmed or programmed with a 0 value, it means that no hole has been previously drilled.<br />

The tool must meet the following conditions:<br />

The tool radius must be smaller than J/2.<br />

The tool radius must be equal to or greater than (J-K)/4.<br />

If these two conditions are not met, the CNC issues the corresponding error message.<br />

B Helical penetration step.<br />

F Feedrate.<br />

S Spindle speed.<br />

T Tool.<br />

D Tool offset.
