Remnant and part picking capabilities of the world’s most powerful sheet metal CAD/CAM software, Radan, are proving to be a vital part of Computer Integrated Manufacturing.
Recol Engineering are regarded as one of the most respected sheet metal fabrication companies in Europe, producing high quality, precision sheet metalwork in stainless and mild steel, and aluminium, largely for the food distribution industry. One of their main production lines is for stainless steel hoppers that measure food quantities for packing.
Their Amada F1 laser and the market-leading Amada EML 3510 NT with full automation, high speed servo-electric punch with combined 4 kw laser are both driven by Radan, from the Vero Software stable, and both have racking towers.
Recol’s head of Engineering Simon Hollin says part picking on the EML is an essential part of their production process. “But we had major issues regarding part picking with our previous software...it just wouldn’t do what we wanted it to, which is why we switched to Radan.”
Recol worked closely with Radan to ensure the software would handle their specific part picking requirements.
Now, when they have nests with large, similar parts, the EML combination laser-punch cuts the part three-quarters of the way out; then arms sucker the part for its final cut before it is stacked in a predetermined position on a bed. When the machine has completed all the part picks the skeleton is taken off and stacked at the back of the machine if it is scrap, or at the front if it can be used as a remnant.
“We can create as many as 50 nests and just leave the machine running overnight. It all helps us to achieve optimum production.”
And Radan’s renowned capability for handling remnants also ensures that material wastage is kept to a minimum, having a positive impact on the company’s bottom line. “We have a number of nests that don’t use the whole sheet. Where we have a remnant it’s transferred into an ‘Unreleased’ folder. Once we’ve run the nest that’s been produced from it it’s transferred into our ‘Remnants’ folder. When we create another nest, Radan scans for remnants first, and puts as many parts as it can on those remnants before going on to use full sheets. This is done automatically and means we don’t have to buy as much raw material.”
