Following presentation of milling a square with T31 and end-milling, we shall now discuss milling a square with a circular Ø 80 miller mounted on the polygon unit in position T24 (example taken from the DECO-2000 26 mm).

Please refer to the previous DECO MAGAZINE edition for information on the principles of programming polar co-ordinates.

Reminder :
The operation line containing the code M198 D-1 to execute machining in polar co-ordinates, must have axis X as master 1, axis C as master 2 and the third axis (e.g. Z) as slave.

The first master axis must, as a matter of course, be a diametral axis (X2, X3 or X4).

Programming with milling radius correction :

For easier programming, it would be useful to use the milling radius correction using functions G41 or G42.

From the tool catalogue, introduce the geometry of the miller in X at the centre of the miller.

For example, miller with a Ø 80 (size recommended for the DECO 2000, 20 and 26 mm capacity):

D = 80, geometry in X = -80.
