Programming a position pattern in ShopMill

Several position patterns can be programmed in succession (up to 20 technologies and

position patterns in total). They are executed in the order in which you program them.

The programmed technologies and subsequently programmed positions are automatically

linked by the control.

Displaying and hiding positions

You can display or hide any positions (Section "Displaying and hiding positions (Page 417)").

Approach/retraction

1. Within a position pattern, or while approaching the next position pattern, the tool is retracted

to the retraction plane and the new position or position pattern is then approached at rapid

2. With subsequent technological operations (e.g. centering - drilling - tapping), the respective

drilling cycle must be programmed after calling the next tool (e.g. drill) and immediately

afterwards the call of the position pattern to be machined.

Tool traverse path

The programmed positions are machined with the previously programmed tool (e.g. center

drill). Machining of the positions always starts at the reference point. In the case of a grid,

machining is performed first in the direction of the 1st axis and then meandering back and

forth. The frame and circle or pitch circle are machined counter-clockwise.

For G code, for rows/frames/grids, a start is always made at the next corner of the frame

or grid or the end of the row. The frame and circle or pitch circle are machined counter-

Working with rotary axes

If a rotary axis in the table is set up on your machine that permits peripheral surface machining,

this axis is supported during drilling (any position pattern, full circle, and pitch circle).

If peripheral surface machining is not possible in the basic position of the machine because

the tool is perpendicular to the end face of the cylinder, the table or head must be swiveled

before machining (swiveling plane).

Example: Compensator with A axis and C rotary table

For peripheral surface machining, the table is swiveled through 90°. This means the C table

rotates about the geometry axis Y and acts as a B axis in G17.
