Machining 101: What is Waterjet Cutting? | Modern Machine Shop

Evan Doran. Waterjet cutting, at its simplest, is the process of a high-pressure jet of water cutting into a material. The technology often compliments other machining techniques such as milling, laser, EDM and plasma. No hazardous material or vapors form during the waterjet process, and neither do heat-affected zones or mechanical stresses.

The squareness errors are corrected through modifying local squareness errors measured with double ball bar to global squareness errors, with the aid of straightness errors measured with multi-laser calibrator.

Compression Springs - End Squareness, Parallelism and Grinding

Since springs are flexible and external forces tend to tilt the ends, grinding to extreme squareness is difficult. A spring may be specified for grinding square in the unloaded condition or square under load, but not in both conditions with any degree of accuracy. When squareness at a specific load or height is required, it should be specified.
