  • Study Unit Toolholding Systems You’Ve Studied the Process of Machining and the Various Types of Machine Tools That Are Used in Manufacturing
    Study Unit Toolholding Systems You’ve studied the process of machining and the various types of machine tools that are used in manufacturing. In this unit, you’ll take a closer look at the interface between the machine tools and the work piece: the toolholder and cutting tool. In today’s modern manufacturing environ ment, many sophisti- Preview Preview cated machine tools are available, including manual control and computer numerical control, or CNC, machines with spe- cial accessories to aid high-speed machining. Many of these new machine tools are very expensive and have the ability to machine quickly and precisely. However, if a careless deci- sion is made regarding a cutting tool and its toolholder, poor product quality will result no matter how sophisticated the machine. In this unit, you’ll learn some of the fundamental characteristics that most toolholders have in common, and what information is needed to select the proper toolholder. When you complete this study unit, you’ll be able to • Understand the fundamental characteristics of toolhold- ers used in various machine tools • Describe how a toolholder affects the quality of the machining operation • Interpret national standards for tool and toolholder iden- tification systems • Recognize the differences in toolholder tapers and the proper applications for each type of taper • Explain the effects of toolholder concentricity and imbalance • Access information from manufacturers about toolholder selection Remember to regularly check “My Courses” on your student homepage.

  • Semi-Solid Slurry Formation Via Liquid Metal
    SEMI-SOLID SLURRY FORMATION VIA LIQUID METAL MIXING A Thesis Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the Degree of Master of Science in Materials Science and Engineering July 2003 by Matthew M. Findon ________________________________________ APPROVED: Diran Apelian, Howmet Professor of Engineering, Advisor Richard D. Sisson, Jr., Professor of Mechanical Engineering, Materials Science and Engineering Program Head ii Abstract New, economical semi-solid metal (SSM) processes rely on forced convection during solidification to influence non-dendritic growth. The fundamental mechanisms that produce SSM microstructures in the presence of forced convection (due to fluid flow) are not fully understood. The objective of this work is to elucidate these mechanisms through the use of a new semi-solid slurry-making technique. Employing an apparatus developed at WPI, two alloy melts are mixed within a static reactor that induces convection and rapid cooling. Experiments carried out with this apparatus, named the “Continuous Rheoconversion Process” (CRP), result in globular semi-solid microstructures throughout a wide range of processing conditions. These conditions include the superheat in the melts before mixing, cooling rate of the slurry through the SSM range, and the presence or absence of inoculants in the melts. The results comprise repeatable sets of semi-solid microstructures having fine particle size and shape factors approaching unity. Even in the absence of melt inoculants, uniform distributions of α-Al particle sizes of about 60µm are attainable. Entrapped liquid is not present in the majority of the samples obtained with the CRP, and irregular particles that form in the process are of a limited distribution.

It is very depth of cut on machining output variables (surface difficult for an operator to select optimum machining roughness and material removal rate) during machining parameters to achieve best surface finish and higher complex shape of copper. Three different levels of input productivity. Therefore, many researchers have focused on parameters were planned as per Taguchi’s L9 orthogonal the effect of machining parameters and selection the array. The parameters are optimised from analysis of mean optimum values of these parameters to determine best (ANOM). Analysis of variance (ANOVA) was employed to surface finish and highest value of material removal rate [1, investigate the effect of machining parameters on the 7].In this research an attempt has been made to produce variables.

The sample test will help prepare machinists to take the actual credentialing exam. None of the questions are duplicates from the actual exam. However, this preparation guide is a useful tool for reviewing technical knowledge and identifying areas of strength and deficiency so that the student has what is needed to do well on the exam. Achieving a NIMS credential is a means through which machinists can prove their abilities to themselves, to their instructors or employers, and to the customer. By passing the NIMS credentialing exam you will earn a valuable and portable credential. Because the test is tough, you will have the satisfaction of proving to yourself and others that you have reached a level of competency that is accepted nationally. Who Wrote the Questions A panel of technical experts, from all areas of the metalworking industry, wrote the questions used on the credentialing exam.
