This Part of the ASME B5.60 standard covers the General Description and Definitions of Terms related to jaw type workholding chucks.

This Standard pertains to the standardization of basic toolholder shank, retention knob, and socket assemblies for numerically controlled machining centers with auto-matic tool changers. The requirements contained herein are intended to provide toolholder interchangeability between machining centers with automatic tool chang-ers of various types. This Standard is the inch solution for basic toolholder shank, retention

The purpose of this Standard is to establish uniform and specific practices for calculating and rounding the numeric values used for inch and metric screw thread design data dimensions only. No attempt is made to establish a policy of rounding actual thread characteris-tics measured by the manufacturer or user of thread gages. Covered is the
