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
traverse.
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
● ShopMill
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.
● G code
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-
clockwise.
Working with rotary axes
Machine manufacturer
Please observe the information provided by the machine manufacturer.
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.
