Goal

An aerospace parts manufacturer was experiencing poor tool life and requested a tool capable of increasing tool life and decreasing tool cost.

Strategy

The customer was machining the surface of a fixture holding six parts using a Z-Carb high-performance 4-flute end mill at a 0.050” axial depth of cut and seven radial passes. Tool failure was traced to an incorrectly programmed conventional milling path, which was corrected to climb milling. After switching to a 9-flute Multi-Carb end mill, the increased flute count enabled higher feed rates and extended tool life from one load (six parts) to six loads (24 parts).

Result

The implementation of the Multi-Carb resulted in a 75% reduction in the number of tools required. Tool change costs decreased by 75%, and the cost per part was reduced by 56%. Overall, the customer achieved a total cost reduction of 56%, generating annual savings of more than $51,000.
