New Nesting Process Cut Delivery from 8 Days to 8 Hours

Cutting Delivery Time with Nesting Process

We recently met a manufacturer, who struggled to get product out in a timely fashion.  If that sounds familiar, read on.  Here is his story.

Before: Order to Delivery in About A Week

This manufacturer of large industrial equipment had an established shear-to-blank, then punch process that went something like this.

An order would come in for 50 of the same part.  The part blanks would be sheared from 10 very large sheets.  This means the shear operator would 1) make two trim cuts per large sheet to square the raw material, 2) measure and cut the first blank, 3) make sure it is square and accurate, 4) repeat four more times per large sheet.  Then he would move and stack the 50 small sheets beside the punch ready for punching the internal holes.  Are you seeing how this could be time consuming and slow delivery times?

How to Evaluate the Nesting Process

Steps to Evaluate the Nesting Process

This post concludes our series on evaluating the nesting process.  We’ve established a foundation for a process review, reviewed the CAD to CAM process, and looked at the order entry side of the equation.  Now we’ll turn to the heart of the nesting process, the actual creation of nests and output of tool paths to the equipment.  This is often the make-or-break element in the process that determines efficiency (material and time), throughput and the overall effectiveness of the sheet metal fabrication process.

Again, we’ll follow our method of first describing the status quo, evaluating it critically, then looking for alternatives.
