MANUFACTURING – LAER & WATERJET CUTTING CALCULATOR
Material Utilisation Sheet
A precise tool.
What is the Material Utilisation Sheet & How does it work?
In laser and waterjet cutting, material utilisation measures how efficiently a raw sheet is converted into finished parts, directly influencing cost and waste.
The utilisation percentage depends on the sheet dimensions, the geometry of each part, and the nesting strategy used to arrange parts on the sheet.
A simple approximation treats each part as a rectangle and calculates utilisation as the ratio of total part area to sheet area, expressed as a percentage.
U = \frac{N \times L_{p} \times W_{p}}{L_{s} \times W_{s}} \times 100
U = utilisation %; N = number of parts; L_{p}, W_{p} = part length and width; L_{s}, W_{s} = sheet length and width.

Frequently Asked Questions
How do I calculate material utilisation?
Multiply the number of parts (N) by each part’s length (Lp) and width (Wp), then divide by the sheet area. Express as a percentage.
What factors affect material utilisation in cutting?
Sheet dimensions, part geometry, and nesting strategy all impact how efficiently raw material is converted into finished parts.
Why is material utilisation important in manufacturing?
It directly influences cost by reducing waste and improving the efficiency of raw material usage.
Can you explain the nesting strategy in material utilisation?
Nesting is arranging parts on a sheet to maximise space, reducing material waste and increasing utilisation percentage.
What is the formula for calculating material utilisation?
U = (N × Lp × Wp) / Sheet Area, where U is utilisation percentage, N is number of parts, Lp and Wp are part dimensions.
