Tips and Techniques for Using a Detail Gouge
Woodturning Tools, Techniques, and Projects Alan N. Leland Tips and Techniques for Using a Detail Gouge Roughing with a Spindle Gouge I prefer to rough out my spindles with a 1 1/4” roughing gouge or a ¾” roughing gouge. Roughing out can be accomplished with a detail gouge but it takes a bit longer and the finished cuts are not as smooth. Used properly a 1 ¼” roughing gouge can leave nearly the same finish as a skew. For roughing cuts: the cut is started approximately 2” in from the tail stock end and proceeds in multiple 2” increments cutting toward the tail stock until approximately 3” from the head stock end of the blank at which point the direction of cut is reversed toward the head stock these cuts are accomplished with the tool handle perpendicular to the blank and the end of the handle down at approximately a 45 degree angle to insure that when the cutting edge makes contact with the wood that the bevel is rubbing and the tool is not cutting until the handle is raised up to start the cut. Hold the tool firmly but not tight as in all turning the tool needs to be easily manipulated and this can not be done with a tight grip on the tool. The feet should be spread apart and the body should be free to move with the cut. To achieve the most control, the flute of the tool is sandwiched between the thumb and fingers of the left hand. The thumb is exerting pressure down toward the tool rest and is griping the flute against the fingers. -

Vibrations in Metal Cutting Measurement, Analysis and Reduction
Vibrations in Metal Cutting Measurement, Analysis and Reduction Linus Pettersson Ronneby, March 2002 Department of Telecommunications and Signal Processing Blekinge Institute of Technology 372 25 Ronneby, Sweden c Linus Pettersson Licentiate Dissertation Series No. 01/02 ISSN 1650-2140 ISBN 91-7295-008-0 Published 2002 Printed by Kaserntryckeriet AB Karlskrona 2002 Sweden v Abstract Vibration and noise in metal cutting are ubiquitous problems in the workshop. The turning operation is one kind of metal cutting that exhibits vibration related problems. Today the industry aims at smaller tolerances in surface finish. Harder regulations in terms of the noise levels in the operator environment are also central. One step towards a solution to the noise and vibration problems is to investigate what kind of vibrations that are present in a turning operation. The vibrations in a boring operation have been put under scrutiny in the first part of this thesis. Analytical models have been compared with experimental results and the vibration pattern has been determined. The second part of the thesis deals with active vibration control in external turning operations. By embedding a piezo-ceramic actuator and an accelerometer into a tool holder it was possible to obtain a solution that can be fitted in a standard lathe. The control system consists of the active tool holder, a control system based on the filtered-X LMS algorithm and an amplifier designed for capacitive loads. The vibration level using this technique can be reduced by as much as 40 dB during an external turning operation. vii Preface The work presented in this licentiate thesis has been performed at the department of Telecommunications and Signal Processing at Blekinge Institute of Technology. -
Lathe Tooling Guide

DS10524_Lathe_Tooling_0921B TORMACH.COM Tormach® CNC Lathe Tooling REFERENCE GUIDE To make the most of a machine purchase, it’s important to understand how cutting tools work and which inserts they pair with. Here is some background on lathe cutting tool and insert terminology: ISO/ANSI Inserts Like metric and imperial measurements standards, the U.S. has its own tool TABLE OF insert classification system; they are called American National Standards Institute (ANSI) designations. All of these ANSI classifications can be converted CONTENTS to the International Organization for Standardization (ISO) classifications, but this guide includes both for easier selection. Cutting Tool Designations 3 Turning Tools Cutting tools are easily identified by their designation, which is universal between ISO and ANSI, and, in the machine shop, tool slang often refers to 6 Boring Bars the insert shape, which is also available in the tool designation. Examples and explanations of designations are available at the start of each section. 7 Turning/ Boring Right-Hand vs. Left-Hand vs. Neutral Inserts Right-hand tools are the most commonly used, because they can be used for most turning applications, including making shoulders on the front of the workpiece. Left-handed tools are typically chosen for back turning and making 11 Grooving/ Parting sharp shoulders on the back of the workpiece. Neutral tools are ideal for Tools complex profiling, thanks to their narrow tips. Insert Shapes 12 Grooving/ Parting There are a variety of insert shapes available, but the general note is use Tool Inserts wider inserts for simple geometry and roughing passes, since they have more durability than a more narrow cutting tool, which is needed for complicated or 12 Threading Tools intricate parts. -
Mechanical Metalworking: from Manual to Computer-Based Processes
August 04, 2021 Mechanical metalworking: from manual to computer-based processes Just like in an ordinary kitchen, there is more to the steelmaker’s kitchen than just the processes where high temperature plays a crucial role, such as boiling, roasting or baking. Before a dish can be served, it needs additional work to make it more appealing. The same is true of metals. Prior to their use, plates, tubes, rods and complex steel castings are subject to cold forming by special metalworking machines and lathes, which become more and more sophisticated each year. History of mechanical metalworking Let’s look first into the history of mechanical metalworking and its origins. Unlike many other processes that are unique to steelmaking, some ideas related to the mechanical working of metal surfaces came from related areas. The ancient Egyptians had devices for drilling holes in stones. Wood machining equipment that later evolved into turning lathes existed in the sixth and seventh centuries BC. Yet these types of processes were not applied to metals for hundreds of years. For a long time, metal surface treatment had several restricting factors. First, it required harder tools. Second, small-batch production did not need high-precision metalworking. Third, the industrial revolution and mass production of uniform products only became a reality in the 18th-19th centuries. The third reason was a key prerequisite for the appearance of mechanical metalworking. Smiths that made goods for individual orders gave way to large industrial manufacturers and factories that had the capacity to produce large quantities of uniform metal goods. Gunsmiths were among the first to appreciate the importance of standardised metalworking. -
