CHAIN CUTTING OF COMMON LINE CUT PARTS SAVES A P. E. P. CUSTOMER AN ADDITIONAL $945.00

This part was cut from ¼" steel.

Most laser shops can cut this without much difficulty and would probably just grid the part across a sheet of material like so:

With P. E. P., the parts will be automatically nested at 90 and 270 degrees as shown below.

With the click of the mouse on just one of the pairs, the common cut selection will automatically generate a new cutter path that cuts the common geometry on both parts simultaneously. The software then prompts the user to assign the same cutter path to identical pairs of parts on all sheets.

• The cutting distance was reduced by 2.33" for each pair of parts. Cutting at 70 inches per minute would save 2 seconds for each pair of parts.

• The common cutting eliminated 1 pierce for each pair of parts or around 4 seconds. Using $150 per hour for costing purposes, this equates to 4 cents/second or a total of 20 cents for each pair of parts. For a quantity of 100 parts (50 pairs) the savings would be $10.00.

The customer then chain cut the parts by clicking on each pair to generate a perfect continuous cutter path in seconds. This added .33 inches of cutting but saved a pierce.

The savings break down like this:

Total time saving per row of 16 pairs or 32 parts total = 32 inches of cutting is around 27 seconds. If piercing time = 4 seconds. Then eliminating 31 pierces = 124 seconds saved or 151 seconds saved for every 32 parts cut. Using 4 cents/second = $6.05 savings for every 32 parts cut.

This order was for 5,000 parts so the savings was a grand total of

 $945.00!
