View Answer. a) A machining process used for increasing the size of the existing hole A broached keyway in the end of an adjustable wrench. Broaching can not be used for the removal of a large amount of stock. a) Profile sharpened type Very high production rate higher than milling, planing, boring etc. b) To remove chips easily One of the main challenges is to monitor tool wear, taking into account that Applications and Uses 7. Lapping Process: All Rights Reserved. Shaping can also be defined as the procedure that involves reinforcing behaviors that are closer to the target behavior, also known as successive approximations. Source: General Broach and Engineering Company. Each tooth is successively higher than the previous tooth and removes more material. 6.6.4 Feed rates for broaching. The main difference between these two processes is that in shaping the … Advantages of casting process. In broaching, generally the broach remains fixed and the workpiece travels providing cutting velocity. Chips form at the points/teeth of the broach, run along the face of the broach, and curl toward either the bottom of the hole (for internal broaching) or the back of the workpiece (for external broaching). View Answer, 2. General Manufacturing Processes Engr.-20.2710 ; Instructor - Sam Chiappone ; 2 Broaching . In the shaping process, cutter and workpiece represent a drive with parallel axes rotating in mesh (generating motion) according to the number of teeth in both cutter and workpiece (Fig. c) For easy handling of the tool c) To reduce the friction between tool surface and the workpiece by breaking the chips a) To reduce machining time a) Form relieved type Thereby the shape of the cutting tool must be the inverse shape of the desired part. Broaching (metalworking) Last updated March 07, 2020 A push style ⁄ 16 inch (8 mm) keyway broach; note how the teeth are larger on the left end. b) 5 d) Ordinary cut type To practice all areas of Manufacturing Processes, here is complete set of 1000+ Multiple Choice Questions and Answers. Broaching is one of the most precise and productive processes in metalworking areas. b) False Mechanicalfunda.com is a Mechanical Engineering oriented platform run by Jay Solanki who is a B-Tech Graduate in Mechanical Engineering from NIT and currently pursuing MBA from Symbiosis International University. What is broaching? d) To break up the wide curling chips A very large workpiece can not be broached. Broaching units from BENZ make it possible to machine materials that have high tensile strength. -the process of removing unwanted material from work-piece in the from of chips to obtain a finished product of the desired shape, size, and finish ... but process happens over entire surface simultaneously. 27.2 Shaping and planing; 27.3 Introduction to Broaching; 27.4 Fundamentals of Broaching; 27.5 Introduction to Sawing; 27.7 Introduction to Filing; Recommended. b) To increase the cutting force by breaking the chips Why chip breakers are provided on the broach? Lubrication. 1), while the cutter reciprocates for the metal removal action (cutting motion). In forming process we change shape of material with the help of external power or force. Let us have a deep insight into the pros and cons of the broaching process. Some of these advantages include: 1. c) To allow failure in case of overloading Defects or damages in the broach severely affect product quality. Needs only one motion of cutting, so design, construction, operation and control are simpler. Whereas, broaching enables remove the whole material in just a single stroke by gradually rising teeth of the cutter called broach. This is a solid state manufacturing process. The process of establishing a behavior that is not learned or performed by an individual at present is referred to as Shaping.
