Short Answer
Sheet Metal Shears operating cost is not only power or consumables. Calculate cost per good part or productive hour from investment, financing, material, energy, tooling, labor, maintenance, scrap, downtime and support.
Investment and capital
Spread purchase, site work, tooling, software, training and financing over realistic utilization, not theoretical maximum output.
Variable operating cost
Review sheet support, backgauge, return or collection and surface protection. Manual handling can become the bottleneck.
Productivity and utilization
Blade clearance, condition and hold-down affect straightness, burr and edge deformation. Define the downstream quality requirement.
Quality and scrap
Do not use a generic thickness figure without material strength. Stainless, aluminum and carbon steel behave differently, so capacity must be verified by group.
Maintenance and downtime
Test several lengths and thicknesses; measure repeatability, straightness, edge quality and setup time, with training and maintenance documented.
Decision equation
Cost per good part equals all relevant period costs divided by accepted parts. Stress-test utilization, exchange rate and downtime.
Frequently Asked Questions
What is the best cost unit?
Good part, good metre or productive hour according to the process.
Is catalogue consumption enough?
No. Use trials, actual readings and an operating range.
How often should cost be updated?
Monthly or after material, currency, utilization or downtime changes materially.
