Milling Fixtures Principles of Their Design and Examples from Practice Third Revised Edition

R. MARKHAM - 3 Examples of Milling Fixtures 26 Copyright, 1912, The Industrial Press, Publishers of MACHINERY 49-55 Lafayette Street, New York City X CHAPTER I ELEMENTARY PRINCIPLES OP MILLING MACHINE FIXTURES* The principal consideration, when designing fixtures that are to be fastened solidly to the table of a milling machine, should be to have the fixture firm enough to admit working the machine and cutter to their limit of endurance. In fact, the fixture should be stronger than the machine itself, and able to resist any possible strain that the cutter can exert. While fixtures should be strong, the movable parts should be so made as to be easily manipulated. All bearing and locat- ing points should be accessible to facilitate the removal of chips and dirt. The action of the clamping devices should be rapid, so that no time is lost in manipulating them. The Milling Machine Vise-False Vise Jaws The first fixture to consider is the milling machine vise, which has a stationary and a movable jaw, against which are placed removable jaws, held in place by means of screws. The stationary-removable jaw generally has connected with it any shelf, pins, or means for locating the pieces to be machined. -

Manufacturing Glossary
MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding. -

Using a Myford Keats Angle Plate
Using a Myford Keats Angle Plate Myford Keats Angle Plate A Keats angle plate is ideal for mounting large items and unevenly shaped castings onto the lathe faceplate for machining. Whilst most available Keats Angle Plates simply have small flanges to attach the unit to the faceplate, the Myford Keats Angle Plate features a full 360o flange for far greater rigidity. An additional advantage of this “full face” flange is that the unit is more balanced and it is far less likely that inconvenient stacks of balance weights will be needed to balance the faceplate. The angle plate is available in two sizes, intended for the 7” and 9” Myford faceplates respectively. The plate illustrated here is the 7” version and the rear flange is 135 mm (5¼”) diameter. The moveable jaw may be reversed to accommodate items of smaller diameter as illustrated in Photo.2 and a through hole is provided in the rear flange to accommodate longer items which project into the headstock mandrel bore. Photo.2 The Angle Plate Set Up For Smaller Photo.3 A Through Hole Facilitates Longer Diameter Items. Items Using The Myford Keats Angle Plate The most usual way to use the Keats Angle Plate is by attaching it to the faceplate of the lathe, although it is a most adaptable accessory and may also be used in a variety of other ways. Photo. 4 shows the angle plate bolted to the faceplate of a customers Myford Super 7 B where it is to be used to turn a bush from the 7 end of a 1 /8” (68.8mm) round bar. -

LATHE WORK for Beginners
ATHE : Wt)ER •i > "HI t YATIBS Book_ GcpigMW_ COPYRIGHT DEPOSHi . LATHE WORK For Beginners A PRACTICAL TREATISE On Lathe Work with complete instructions for properly using the various tools, including complete directions for wood and metal Turning, Screw Cutting, Measur- ing Tools, Wood Turning, Metal Spinning, etc., and instructions for Building Home-made Lathes with their attachments, etc. BY RAYMOND FRANCIS YATES author of 'Model Making," " Shop Practice for Home Mechanics," "Soldering and Brazing," etc. Fully Illustrated with 167 Line drawings and photographs NEW YORK Ms Copyrighted 1922, by THE NORMAN W. HENLEY PUBLISHING COMPANY Printed in the U. S. A. APR 26 1922 OCI.A661481 PEEFACE The lathe is the master tool. It has taken a great part in the progress of civilization and of all the machines of production, it is the most important. In the tremendous mass of technical literature published in the United States, there is not one volume devoted wholeheartedly to the lathe from the standpoint of the beginner—the man who de- sires to learn its uses as an amateur. There are many volumes dealing with large lathes from the industrial viewpoint, but these are more or less useless to the man who knows little or nothing about lathe operation. In this volume the writer has endeavored to set forth the basic principles of lathe operation and manipulation, in a way that will interest and in- struct the layman. The book starts at the very bottom and ends at a point beyond which the average amateur does not care to go. The author desires to acknowledge his thanks to the following men who assisted in the prepara- tion of the volume.
