5、 85 approved this project at their annual meeting in 1961 and created technical committee TC-14 to prepare such standards.In 1962 the USA Standards Committee 85 was divided and technical committees identified with the general area of metal cutting were transferred to a new USA Standards Committee B9
6、4.The first meeting of TC-14,reporting to USA Standards Committee B94,was held in December 1962.It was at this time decided to divide the general subject into three areas;i.e.,hobs,gear shaper cutters and shaving cutters.The initial activity was to prepare a proposal for a USA Standard on hobs,using
