START BURNING

This function is used to indicate a single burning start, in which case the operator will be prompted to indicate the start position and possibly the tool direction or to create burning starts for all the holes on the plate automatically. Parallel burning is supported, vertically for the outer contour and horizontally for the holes.

The switch between single and parallel starts is made with OPTIONS.

To create a parallel start for the outer contour the user has to indicate the following points (Y1 refer to the left tool set and Y2 to the right tool set):

1. Start position Y1 parallel

2. End position Y1 parallel

3. End position Y1 single (OPERATION COMPLETE means the same point as end Y1 parallel)

4. Start position Y2 parallel

5. End position Y2 parallel

The corner loops at the positions 1) and 5) will be split into starting and ending hooks. These hooks must have been created in PLCM in order to extend outside the raw plate automatically, cf below.

The system checks that parallel burning is possible (Y1 and Y2 cannot be too close, the lengths of the sides to be burned must be equal).

To create a parallel start for a hole the user must first create a gap in the hole to be burnt by Y1. Then the user indicates the starting point for Y1 (in the gap) and the starting point on the second hole for Y2. If the holes are identical and are created on the same y-coordinate, the system automatically creates a gap and a start on the second hole in the correct position.

Normal nesting hooks should be used for the holes.
