The Consensus Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests have had an opportunity to participate. The proposed code or standard was made available for public

FOREWORD (T

9、his Foreword is not part of ASME B94.33-1996.) This Standard for jig bushings was approved and designated as an American Standard by ASA in April, 1935. The use of this Standard by industry necessitated revision in December, 1937. The Standard was revised and approved by the Sectional Committee in M

10、arch, 1941. Approval and designation by ASA was given in August, 1941. The Standard was reaffirmed in 1949. The TC-8 Committee was reactivated in December of 1957 to review and revise the Standard, if necessary. Requests for additional lengths, locking devices, locking dimensions, and a uni- fied ma

11、rking system by industry users were considered and approved by the committee in December, 1958. Further additions and deletions were agreed upon by the committee at a meeting in April, 1960. With the exception of counterbores, the draft was approved. Specifications for counter- bores were added, and

12、 the draft was distributed to committee members November 1, 1960. Committee members approved the draft, and it was submitted to TC-17 for approval. ASA ap- proval was granted on June 22, 1962. Fractional dimensions were changed to decimal inch, and the document was reviewed for conformance with Amer

13、ican National Standard Decimal Inch, ANSI B87.1-1965. The current revision was approved by the American National Standards Institute on Decem- ber 27, 1996. . 111 ASME STANDARDS COMMITTEE B94 Cutting Tools, Holders, Drivers, and Bushings (The following is the roster of the Committee at the time of a

23、 (c) Round clamps with standard socket head screws are designed for use with the fixed side of the slip-fixed renewable bushing and are to be used where engineers prefer the clamp over a lock screw. These clamps are located from the same point as the lock screw (as shown as R in the standards); ther

24、efore, the same locating jigs can be used to drill plus tap the necessary holes in the jig or fixture. To change to the round clamp in old fixtures, remove the conventional screw and use the same tapped hole to secure the new clamp with standard socket head screw. (d) All dimensionsare given in inch
