Shaper, Milling & Gear Cutting M/c SHAPER Mr. K. Gobivel Assistant Professor / Mechanical KCG College of Technology Types of Shaper Types of shaper: Shapers can classified into many types based on several criteria: Based on the type of driving mechanism used • – Crank and slotted lever driving mechanism type • – Whitworth quick return driving mechanism type • – Hydraulic driving mechanism type Based on the table design • – Plain Shaper • – Universal Shaper Based on the position of the reciprocating ram used • – Horizontal shaping machine (Most common type of shaper used) • – Vertical shaping machine • – Travelling head shaping machine Based on the type of cutting stroke of the tool • – Push out type • – Draw cut type Shaper Mechanism In shaper, rotary movement of the drive is converted into reciprocating movement by the mechanism contained within the column of the machine. The reciprocating movement of the ram and the quick return mechanism of the machine are usually obtained by any one of the following methods 1. Crank and slotted link mechanism 2. Whitworth quick return mechanism 3. Hydraulic shaper mechanism Whitworth quick return mechanism Hydraulic shaper mechanism Shaper, Planer and Slotter M/c Planer Slotter Difference b/w three types Shaper: Operations Types of operations • Machining horizontal surface • Machining vertical surface • Machining angular surface • Cutting slots, grooves and keyways • Machining irregular surface • Machining splines or cutting gears Horizontal & Vertical Surface Making Chuck key Making V Block Tool slide is tilted for V block angle Making an external key way Making of Dovetail Making of rack Making of an internal keyway Machining a contour surface.

Shaper Machine: Definition, Working, Types, Operations, Specification, Advantages, Disadvantages, and Application (With PDF) In Manufacturing Technologyby Amrit KumarFebruary 28, 2019Leave a Comment Table of Contents Shaper Machine Definition: Working Principle of Shaper Machine: Types of Shaper Machine: Operations Performed on Shaper Machine: Parts of a Shaper Machine with Function: Specification of Shaper Machine: Advantages of Shaper Machine: Disadvantages of Shaper Machine: Applications of Shaper Machine: Hydraulic Shaper Mechanism in Shaper Machine: Conclusion: Hello, readers in today’s article, we will learn how a shaper machine works also we learn about the parts, types, operations, specification, advantages disadvantages, and applications of a shaper machine. So let’s start with the definition of shaper machine. Shaper Machine Definition: The Shaper is a reciprocating type of machine tool basically used to produce Horizontal, Vertical or Inclined flat surfaces by means of straight-line reciprocating single-point cutting tools similar to those which is used in lathe operation. The flat surface produced may be horizontal, vertical or inclined at an angle Working Principle of Shaper Machine: A shaper machine is working on the following principle: A shaper machine holds the Single point cutting tool in ram and workpiece is fixed over the table. The ram holding the tool reciprocates over the workpiece and metal is cut during the forward stroke called a cutting stroke and No metal is cut during its return stroke is called an Idle stroke. The feed is given at the end of the cutting stroke. Generally, the cutting stroke is carried out at slow speed and the idle stroke is carried at high speed with the help of quick return mechanism.

New Technology of Gear Cutting That Contributes to Customer's
Mitsubishi Heavy Industries Technical Review Vol. 49 No. 3 (September 2012) 29 Latest Gear Cutting Technology that Improves Customer Productivity (Increase in Speed of ST Series NC Guide Gear Shaping Machine) TOSHIMASA KIKUCHI*1 YOSHIHIRO NOSE*2 KATSUHIDE YABE*2 TAKAHIDE TOKAWA*3 Mitsubishi Heavy Industries, Ltd. (MHI) was the first company in the world to establish the dry cut system, which contributes to a clean work environment and high productivity by eliminating the use of cutting oil for the processing of gears. We have been actively offering new technologies, including the one mentioned above, that satisfy the needs of customers. There is a growing need for further improvement of productivity, including the reduction of processing time, from mass production lines of automobiles and other products, as well as from job shops that manufacture multiple types of gears in small quantity. In this paper, we will introduce the latest technologies for productivity improvement of gear cutting machines, taking the ST series NC guide gear shaping machine, one of the gear cutting machines developed by MHI, as an example. |1. Introduction A gear shaper is a gear cutting machine that is generally used to process internal gears and stepped gears. As shown in Figure 1, the cutter and the workpiece are rotated synchronously while the cutter is moved back and forth for processing gears. The gear shaper features a unique function, where a helical guide is used to move gears helically along the cutter lead for the processing of helical gears that are twisted along the helical path. The helical guide needs to be replaced responding to the change of the cutter lead, but helical guides are expensive and replacement requires a fair amount of time and a lot of skill.

Safeguarding Machinery and Equipment: General Requirements
Safeguarding Machinery and Equipment General Requirements About WorkSafeBC WorkSafeBC (the Workers’ Compensation Board) is an independent provincial statutory agency governed by a Board of Directors. It is funded by insurance premiums paid by registered employers and by investment returns. In administering the Workers Compensation Act, WorkSafeBC remains separate and distinct from government; however, it is accountable to the public through government in its role of protecting and maintaining the overall well-being of the workers’ compensation system. WorkSafeBC was born out of a compromise between BC’s workers and employers in 1917 where workers gave up the right to sue their employers or fellow workers for injuries on the job in return for a no-fault insurance program fully paid for by employers. WorkSafeBC is committed to a safe and healthy workplace, and to providing return-to-work rehabilitation and legislated compensation benefits to workers injured as a result of their employment. WorkSafeBC Prevention Information Line The WorkSafeBC Prevention Information Line can answer your questions about workplace health and safety, worker and employer responsibilities, and reporting a workplace accident or incident. The Prevention Information Line accepts anonymous calls. Phone 604 276-3100 in the Lower Mainland, or call 1 888 621-7233 (621-SAFE) toll-free in British Columbia.

LADD, ADMINISTRATOR OFFICE OF APPRENTICESHIP CERTIFICATION DATE: __________________ CERTIFICATION NO: ______________________ FOREWORD IUE-CWA, the Industrial Division of the Communications Workers of America (CWA), AFL-CIO, CLC. has believed from the beginning of our existence that the ability of working men & women to perform in highly skilled, technical positions is unlimited when training and educational resources are made available. We recognize the need for structured training programs to maintain the high level of skill and competence demanded in the manufacturing industry. Our progress as a union and the strength of our nation will be measured in part by our ability to provide an avenue of opportunity for all 25 workers to achieve ultimate skills in their chosen craft. Registered apprenticeship programs are the most practical and sound training system available to develop individuals into skilled journeyworkers, and to ensure industry an adequate supply of skilled workers. Title 29, Code of Federal Regulations (CFR) part 29, outlines the requirements for registration of acceptable apprenticeship programs for Federal purposes, and sets forth labor standards that safeguard the welfare of apprentices. Such registration may be by the U.
