Canned cycles (·M· model)<br />

1.10 G210. Bore milling canned cycle<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 />

Programming format in Cartesian coordinates:<br />

G210 Z D I J K B<br />

I<br />

Parameter definition:<br />

Z Reference plane.<br />

Defines the reference plane coordinate. It may be programmed either in absolute or<br />

incremental coordinates, in which case it will be referred to the starting plane.<br />

If not programmed, it assumes as reference plane the current position of the tool.<br />

D Safety distance.<br />

Defines the distance between the reference plane and the surface of the part where the milling<br />

is to be done. If not programmed, it assumes 0.<br />

I Machining depth.<br />

Defines the machining depth. It may be programmed either in absolute or incremental<br />

coordinates, in which case it will be referred to the reference plane.<br />

J Hole diameter.<br />

Defines the nominal diameter of the hole. The sign indicates the direction of the helical path<br />

associated with the machining of the hole (positive if clockwise and negative if<br />

counterclockwise).<br />

If not programmed or programmed with a value smaller than the diameter of the active tool,<br />

the CNC issues the relevant error message.<br />

K 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 Penetration step.<br />

It defines the penetration step when machining the hole.<br />

With a positive sign, it will mill the bottom of the hole.<br />

With a negative sign, it will not mill the bottom of the hole.<br />
