achieved. Among them‚ Abrasive Water Jet cutting proves to be a promising area since there is no possibility of thermal damage to the material. AWJ cutting belongs to the mechanical group of non-conventional techniques which uses the mechanical energy of water and abrasives to perform the material removal process. Water is pumped at a high pressure and abrasive is added to the stream in such a way that the momentum of water stream is transferred to the abrasives. Hence‚ the abrasive gets accelerated to

No. 78307 By Harry Levinson The Abrasive Personality The corporate president stared out the window of his skyscraper office. His forehead was furrowed in anger and puzzlement. His fingers drummed the arm of his chair with a speed that signified intense frustration. The other executives in the room waited expectantly. Each had said his piece. Each had come to his and her own conclusion about the problem. Darrel Sandstrom‚ vice president of one of the corporation’s major divisions‚ was

Abrasive flow machining 1. Introduction Abrasive flow machining (AFM) was firstly developed fifty years ago by Extrude Hone Corporation‚ USA. By using the liquid viscoelastic material with easy flowability made of polymer and abrasive grains‚ AFM can be used to polish‚ deburr and radius for the workpiece. There are three kinds of AFM: one-way AFM‚ two-way AFM and orbital AFM [1]. In this case to manufacture the cylinder heads‚ consider of two-way AFM is much more widely used and its technology

Industrial training course is a prerequisite for any degree student to graduate. It is a component of learning programme that provide an opportunity for the students to learn in the working environment in order to prepare them with the real working environment (UKM‚ 2011). The objective of this course is to improve the quality of graduates by exposing them early to the reality of employment world. Students that have industrial training experience will have advantages compare the others students that

ABRASIVE JET MACHINING INTRODUCTION:- IT IS A PROCESS OF MATERIAL REMOVAL THROUGH THE ACTION OF A FOCUSED STREAM OF FLUID WITH ABRASIVE PARTICLES. IT IS ESPECIALLY USED FOR MACHINING SUPER ALLOYS‚ CERAMICS; GLASS AND REFRACTORY MATERIAL. IT IS ONE OF THE NON-POLLUTING METHODS AVAILABLE FOR MACHINING HARD MATERIALS TO PRECISION DETAILS. IN ABRASIVE WATER JET MACHINING THE ABRASIVE PARTICLES UTILIZES WATER JETS TO ACCELERATE OR DECELERATE THEIR SPEEDS DEPENDING UPON THE TYPE OF MATERIAL TO BE MACHINED

1. The theory of motivation that I feel best explains Simpson’s recent behavior is the Goal setting theory. While his case has characteristics of other theories as well‚ this seems to be the theory that best explains it. This theory focuses on the idea that conscious ideas regulate a person’s actions. People direct their behavior in such a way as to attain what they deem as acceptable goals. For Harry‚ this was the role of supervisor. He shows that he has conscious ideas of this because he knows
