initiated in December of 1961 to establish standards for gear cutting tools USA Standards Committee B5 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 B5 was divided and technical committees identified with the general area of “metal cutting” were transferred to a new USA Standards Committee B94 The first meeting of TC-14, reporting to USA Standards Committee B94, was held inDecember 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 the industry standards (MCTI) as the basis for consideration A proposal covering hobs was submitted to industry in September 1964 and on June 22, 1966, itwasapproved by the USA StandardsInstituteanddesignated B94.7-1966 A proposalcoveringshapercutterswassubmittedtoindustryin December 1966 for review and comments All of the responses were considered in a meeting of TC-14 in November 1967 and they then approved a final proposal The B94 TC15EditorialCommitteereviewedtheproposal and itwassubmitted in March 1968 to the USA Standards committee B94 for letter ballot Followingapproval by B94,theproposalwasapproved by thesponsor, ASME, on June 13, 1968 It was approved by the United
