Fiber Laser Cutting

DFM file review on every new job before sheet is loaded. DXF file is checked for minimum hole diameter compliance against material thickness, kerf compensation status, feature spacing adequacy, and assist gas specification relative to downstream process. Jobs failing DFM review are returned with specific correction notes before cutting begins.

CAD/CAM nesting verification confirming part quantity, orientation, grain direction where specified, and micro-joint placement before the cutting program is approved and the sheet is loaded onto the cutting bed.

First-off dimensional check on all critical dimensions including hole pattern centre-to-centre, profile envelope, internal cutout position, and overall blank dimensions before full sheet batch is cut. Performed using calibrated digital calipers and coordinate measurement against the DXF reference geometry.

Edge burr and dross inspection on first-off and batch samples. Dross on the exit face of the cut indicates incorrect cutting parameters for the material and thickness being processed. Any dross formation triggers parameter adjustment before the batch proceeds.

Assist gas verification confirming correct gas type is active before cutting begins on each job. Nitrogen and oxygen lines are clearly labelled and the active gas is confirmed on the machine controller display before the first pierce cycle.

Dimensional coordinate check on complex profiles and hole patterns using calibrated measurement against DXF reference geometry. Positional deviation outside plus or minus 0.1mm on any critical dimension triggers machine recalibration before the batch continues.
