Copyright O 1985 by THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS All Rights Reserved Printed in U.S.A. - _LI- . 1 FOREWORD (This Foreword is not part of ANSI/ASME 894.6-1984.1 It has been commonly appreciated that in the production of knurling there were some diffi- cult
25、problems, and it appeared that a solution to many of them could probably be found in de- veloping a knurling tool based on a diametral pitch system, as distinguished from the customary circumferential pitch formulas in use. A diametral pitch system was first given consideration by the Company Member
26、 Conference of the American Standards Association. At its meeting of March 20, 1947, the Conference voted to establish a fact-finding Conference Subcommittee to consider the problems involved in knurling and the need for standardization in the field of knurling practice. On November 10, 1947, the Co
27、nference Subcommittee presented a report (CMC 50) and concluded that a Technical Committee should give consideration to improving knurling. At its meeting of December 2, 1948, the B5 Sectional Committee reported that the Mecliani- cal Standards Committee of the ASA had requested that consideration b
28、e given to the establish- ment of a project on knurling. This request was approved at that time, and B5 Technical Com- mittee 27 was thereupon organized in June 1949. TC27 held its first meeting in New York City on November 3,1949. A proposed standard was prepared by TC27, and in September 1952 it w
29、as distributed to industry for review and comments. TC27 prepared a new draft, dated March 1953, taking into Consideration the comments and suggestions received from the industry review. The proposed standard was approved by the Sectional Committee, the sponsor, and finally by ASA on Octo- ber 15, 1
30、953. It was designated ASA B5.30-1953. A revision of the standard was approved by ASA on August 18, 1958, and it was published as ASA B5.30-1958. In November 1961, the ASA Mechanical Standards Board approved the request of the B5 Sectional Committee sponsors that a separate project be initiated unde
31、r ASA Procedure on the topic of cutting tools. As a result of this action, a new project was initiated, and ASME ac- cepted sponsorship. The Committee was designated B94 Cutting Tools, and the activity on cut- ting tools was removed from the B5 Sectional Committee. The designation numbers of the tec
32、h- nical committees were changed to conform with the new sectional committee organization. B5 Technical Committee 27 was changed to B94 Technical Committee 11. As required by ASA procedure, the Committee reviewed the proposal and approved some changes in the recommended tolerance on work blank diame
33、ter before knurling, as shown in Table 3. Other changes, of an editorial nature, were made to bring the standard into confor- mance with the B94 format. The present edition of this Standard was approved as an American National Standard on November 28, 1984. ASME 874.6 44 0757670 0048674 3 111 0 . 11

Appleton, Pratt (h) when diagonal, to indicate its diametral pitch, helix angle, and hand of the angle. 6 RECOMMENDED TOLERANCE ON KNURLED OUTSIDE DIAMETERS Three classes of tolerances are shown in Table 3. These classes and recommended applications are a
41、s follows. (a) Class I Tolerances., This classification may be applied to straight, diagonal, and raised diamond knurl- ing where the knurled outside diameter of the work need not be held to close dimensional tolerances. Such applications include knurling for decorative effect, grip on thumbscrews,
42、and inserts for moldings and castings. (b) Class II Tolerances. This classification may be applied to straight knurling only and is recommended for applications requiring closer dimensional control of the knurled outside diameter than provided by Class I tolerances. (c) Class III Tolerances. This cl
43、assification may be ap- plied to straight knurling only and is recommended for applications requiring closest possible dimensional con- trol of the knurled outside diameter. Such applications include knurling for close fits. 7 THE TRACKING CORRECTION FACTOR O Use of the preferred pitches for cylindr
44、ical knurls, shown in Table 4, results in good tracking on all frac- tional work blank diameters which are multiples of The width of the knurling should not exceed the diameter of the blank, and knurling wider than the knurling tool cannot be produced unless the knurl starts at the end of the work.
45、KNURLING D, = diameter of work blank N, = number of teeth produced on work blank (as mea- sured in the transverse plane) P = diametral pitch on tool P+ = diametral pitch produced on work blank (as measured in the transverse plane) by setting tool axis at an angle Ji with respect to work blank axis +
46、 = angle between tool axis and work axis FIG. 10 DIAGONAL AND DIAMOND KNURLING 1/64 or l/32 in., depending on the pitch selected. To accomplish this, the work surface must be evenly marked during the first revolution of the work, which requires pitch circles to roll without relative slippage. Theref
47、ore, extent of penetration of the work by the knurl during the first revolution must be considered. Be- cause of the many variables involved in knurling prac- tice, such as cam contours, hardness of the material, elasticity of machine tools and tool holders, etc., the method of determining the requi
48、red correction is neces- sarily empirical. Accordingly, the tracking correction factor Q has been incorporated in knurl specifications, shown in Table 4, on the basis of experimental work and experi- ence, and has provided good tracking for general knurl- ing conditions. 8 DIAGONAL AND DIAMOND KNURL
49、ING WITH STRAIGHT TOOTH KNURLING TOOLS2 Diagonal knurling on work blank may be accom- plished by setting the axis of the knurling tool at an angle to the work axis (see Fig. IO). Diamond knurling can be produced by the use of two straight knurls when their axes are swivelled from the work blank axis in accordance with the above formulas. In using straight knurls to produce diagonal and diamond knurling, the transverse diametral pitch and number of teeth on the work will not be the same as that of the tool. KNURLING For example, if 30 deg. diagonal knurling w
