Fast Nesting

Two options for Nesting are provided in the Nesting Tab viz. Fast Nesting and Optimal Nesting.

Nested layout with Fast Nesting

• Grid Fit for Single Parts:For nesting a single part, both Fast Nesting and Optimal generate a uniform grid like arrangement of nested parts. This feature is used for improving material utilization. Fast Nesting first analyses the part type and generates a suitable unit (i.e., either a single instance of the same part or a suitable pair) which can be repeated at fixed distances in horizontal and vertical directions.

• Center of Gravity Fit for Multiple Parts: For nesting multiple parts, Fast Nesting uses the position of the centre of gravity of each part to achieve a better nested pattern compared to Grid Fit.

• Circular shaped Parts: Circles and parts, whose outermost boundary is a complete circle, are treated specially. It is well known that such parts offer the best utilization, when they are arranged in hexagonal packing structure. With Fast Nesting, CAMWorks Nesting uses special internal parameters, which decide whether such parts should be nested in a hexagonal or rectangular pattern.

• Fast Nesting considers the angle list input by the user while generating the nested layout in both Grid  Fit and Center of Gravity Fit pattern.

Note:  If used for nesting multiple parts, the material utilization factor resulting with Fast Nesting is some percentage factor less compared to Optimal Nesting. However, the time taken for Fast Nesting is considerably less compared to Optimal Nesting.

You must consider the material utilization factor and time factor to decide the type of Nesting - Fast Nesting or Optimal Nesting.
