Garza Güell 27/12/2012 PRODUCT DESIGN AND MANUFACTURING PROCESS INDIVIDUAL EVALUATION 1. EDM (Electrical discharges machine ) and WEDM ( Wire Electrical discharges machine). • Fundamentals of process; Principles of EDM Electrical Discharge Machining (EDM) is a controlled metal-removal process that is used to remove metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape

Sutton v. Tomco Machining‚ Inc. 129 Ohio St.3d 153‚ 2011-Ohio-2723 Facts of the Case: In this appeal‚ DeWayne Sutton‚ an employee of Tomco Machining‚ Inc. claimed that he injured his back on the job while disassembling a chop saw. Sutton alleged that he was fired within one hour of reporting the workplace injury to Tomco’s president‚ Jim Tomasiak. No reason was specified in the termination; however he was told the firing was not due to his work ethic or job performance or because he had broken

Disadvantages Advantages CNC machines are more expensive than manually operated machines‚ although costs are slowly coming down. CNC machines can be used continuously 24 hours a day‚ 365 days a year and only need to be switched off for occasional maintenance. The CNC machine operator only needs basic training and skills‚ enough to supervise several machines. In years gone by‚ engineers needed years of training to operate centre lathes‚ milling machines and other manually operated machines. This

Did the milling serve to do electronic processes? No‚ It didn’t. Milling served to do mechanical processes. In early years‚ milling was often viewed as only a roughing operation to be followed by finishing with a hand file. The idea of reducing hand filing was more important than replacing it. Were the milling machines involving? Yes‚ they were. Milling machines were evolving from the practice of rotary filing. 1. There were two characters talking in a reception office. 2. The two characters were

Hybrid ceramic ball mill ( ceramic sand mill ) is mainly used for materials ‚ grinding fineness product evenly‚ saving power . Dry grinding can also be wet . Ceramic ball mill working principle can produce different liner types needed to meet different needs. Fineness of grinding operations ‚ relying on self- control grinding time . Motor starting from decompression to reduce the starting current ‚ the structure is divided into integral and independent style . Ceramic ball mill working principle

INTRODUCTION Surface modification is a miraculous application of Electric Discharge Machining (EDM). It can modify the conductive material surface by both removing material from the surface and depositing material on the surface. It can remove or deposit material from the work surface through controlled electrical sparks by the process of melting and evaporation. The controlled sparks erode material from the work and tool surface within very short intervals of time. Study of surface morphology widens

Computer Numerical Control (CNC) machines are automated milling devices that make industrial components without direct human assistance. They use coded instructions that are sent to an internal computer‚ which allows factories to fabricate parts accurately and quickly. There are many different types of CNC machines‚ ranging from drills to plasma cutters‚ so they can be used to make a wide variety of parts. CNC Computer Numerical Control machines are widely used in manufacturing industry. Traditional

TITLE: Ball mill grinding. INTRODUCTION Indeed the ball milling means‚ the reduction of particles to smaller sizes with the help of a ball mill. It can be done in two ways. They are‚\ Dry milling Wet milling Generally‚ this has porcelain or steel ball as the grinding media. Commiution is occurred by several methods in the ball mill grinding. They are compression‚ impact and shear between the moving grinding media and the particles. The rate of this depends on some factors. These

OVERVIEW This is a basic case in Activity-Based Costing (ABC) and Activity-Based Management (ABM). There is enough richness to the fact-situation to create a non-trivial calculational challenge for students without taking the case beyond an "introductory" level. Also‚ the business context for the calculations is rich enough to support good discussion on the managerial implications. I use Tijuana Bronze as the introductory case on ABC/ABM in the required managerial accounting course at Tuck and
