Common line nesting reduces cutting time
Sheet metal nesting software considers the practicality of component shape and layout when generating nests which incorporate common line cutting.
Soaring material costs make any improvements in sheetmetal nesting and profiling efficiency worthwhile Sharing a single cut path between neighbouring components can provide a tighter nest and reduce the overall cutting time, but there are technological problems

One off-line system controls punches, profilers
The flexibility of transferring parts between machine tools attracted a laser profiling company to use one CADCAM system for a variety of punching and profiling machines.
CAD/CAM modules designed for sheet/plate profiling
In CAD/CAM modules specially designed to automate the programming of sheet metal cutting machines, as the mouse is dragged to define a window, the nesting is generated instantly and automatically.
Lantek's nesting software considers the practicality of component shape and layout when generating nests which incorporate common line cutting, to overcome these difficulties.
Typical problems encountered during common line cutting include small parts tipping up; components sliding under their neighbours, resulting in recutting; larger parts distorting, which can stop the laser cutting any further; witness marks on component edges; and warping of the sheet itself.
The Lantek Expert software solves these problems by only common line nesting pairs of parts, and those which have an identical side length of at least 100mm.

Software allows real time progress chasing
A system that provides integrated management of the whole production process in sheet metal manufacturing environments passes on information generated to manufacturing.
Cut and punch CAD/CAM has management functions
In a desire to offer latest-generation solutions for the sheet metal-working world, a fully modernised star system for cut and punch CAD/CAM includes management.
This helps to keep the sheet stable by avoiding distortion, and ensures good edge quality.
The software also calculates a safe path around the parts which have already been cut, avoiding potential collisions.
Elsewhere gaps are automatically left between components to produce a reliable result.
Going one stage further, the software can introduce bridging between small parts to connect them to one another.
The result is fewer piercing operations which allows several small parts to be cut in one continuous path.
Bridging also adds to the stability and security of the whole sheet.
Small parts are prevented from falling into the bed of the machine, and linking them together adds to the rigidity of the full sheet of products.
Combining these two approaches to nesting will help Lantek users reduce cutting times with shorter paths; reduce the number of piercing operations; improve material utilisation; and minimise the use of consumables, directly adding to profit margins.
