snijplan

Snijplan,often translated as cutting plan, is a document or plan used in manufacturing and crafts to determine how a stock material (such as sheet metal, plywood, fabric, or leather) should be cut into the required parts. The goal is to meet the bill of materials while minimizing waste, ensuring correct grain or pattern orientation, and optimizing cutting time.

A typical snijplan includes a parts list, material specifications, dimensions, kerf allowances, nesting layout, and cutting sequence. It may be generated manually or by software that performs 2D nesting to arrange patterns on a sheet to reduce waste. Important considerations are stock size, grain direction, symmetry, cropping, and feasibility of the cut order.

In practice, snijplans are used in industries such as woodworking, textiles, metal fabrication, and plastics. Tools range from physical templates and paper layouts to computer-aided design (CAD) and nesting software. The plan informs the cutting machine settings and the sequence of operations on the shop floor.

Limitations include the complexity of parts with many shapes or curved edges, variability in raw material, and changes in demand or stock. An effective snijplan balances material efficiency with production speed and accuracy.
