Advanced NC Programming
Focusses on reducing machine cutting cycle time by optimizing machine motion to minimize unnecessary motions and reduce wear.
- Automatic common edge cutting using schemes such as, "two parts, one pierce", automatic slitting cuts and combination cutting.
- Auto-chain and bridge functions allow outside contours in a complete nesting to be continuously cut with a single pierce.
- Bevel programming including knife, land and K-bevels.
- Tip-up part crash avoidance defines the cutting sequence of a nesting layout to ensure the cutting head does not pass over a previously cut component. Thus saving time and eliminating head crashes.
- Pre-pierce all start points, then cut.
- By dynamically adjusting process cutting parameters, depending on part geometry, the system ensures that the best part quality is achieved at the fastest production rate possible. This is particularly useful with laser and water jet cutters.
Examples
Automatic Cropping
The automatic cropping function provides options to separate the cut portion of the plate from the remnant. The following diagrams illustrate two options:
The first generates a step path that is a specified clearance distance from the parts.
The next diagram illustrates a complex profile cropping of the sheet at a specified clearance from the parts.
Automatic Slit Cut
This procedure cuts entities from multiple parts along a common line. The following diagram illustrates the process. All cuts are for the full length of three parts. The first cut is from the bottom to the top of three parts. There is a rapid move to the right and the second cut is from the top to the bottom of three parts. All the internal common lines are cut first, then the external contours are cut in steps 5 through 8.
Previous Cut Pickup
This cutting sequence places a lead-in, after a rapid move, where a common cut has already taken place. This avoids an additional pierce.
The following diagram illustrates the placement of a lead-in, between cuts 4 and 5, where cut 2 previously occurred.
