Break-down of workpiece costs

Tooling costs: 2-6%, material costs: 14-18%, manufacturing costs: 78-82%.

Increase in productivity Increase of productivity by 30% results in reduction of workpiece costs by 19%. Due to the improved utilization of the available machine capacity, considerable cost reduction per workpiece becomes possible.

Increase of tool life Increase of tool life by 30% results in reduction of workpiece costs by 1%. As the average tool costs amount to only 2-6% of the workpiece costs, prolonging tool life typically can only reduce total costs minimally.
