Testing & Quality Assurance

Magnetic abrasive finishing can deburr and create highly polished, smooth surface finishes. It can also remove microcracks, recast metal, metallurgical phase changes, visible scratches and damaging residual stresses.

Superhard finishing tools may benefit machined parts via finer surface finishes, greater wear resistance and harder, stronger microstructures. Also, some of the tools can last longer than their conventional counterparts.

Software options from basic to advanced for on-machine part measurement.

Ensuring accurate measurement of parts with ever tighter tolerances. As part tolerances continue to tighten across the board, accurately and consistently measuring them becomes more of a challenge.

Upgrades and multifunction technology improve CMM inspections.

Using on-machine inspection to check part quality can reduce lead times.

Low-cost, portable, surface-roughness measurement gages help users perform quick inspections on the shop floor.

Obtaining a fine surface finish when high-speed machining.

Due to the exceptional strength of IN 100, INCO 718 and other nickel-based alloys, they're difficult to machine. The author, who spent 40 years endmilling these aerospace materials, discusses their unique characteristics and methods for successfully machining them.

The author offers tips about making interrupted cuts while turning. He also discusses the differences between interrupted cuts in turning and milling and various types of materials.

Author discusses the advantages of CVD-diamond tools compared to other types of diamond tools. He also explains how CVD-diamond tools are manufactured and gives case histories involving their usage.

Equipping toolchangers with nylon abrasive-filament brushes can greatly enhance process economics and the flow of parts. Case histories of in-machine deburring operations support these contentions, and the author describes how such systems should work.
