  • Improvement of Punch and Die Life and Part Quality in Blanking of Miniature Parts
    Improvement of Punch and Die Life and Part Quality in Blanking of Miniature Parts DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Soumya Subramonian Graduate Program in Mechanical Engineering The Ohio State University 2013 Dissertation Committee: Dr.Taylan Altan, Advisor Dr.Blaine Lilly, Advisor Dr.Gary L.Kinzel Dr.Jerald Brevick Abstract Blanking or piercing is one of the most commonly used sheet metal manufacturing processes in the industry. Having a good understanding of the fundamentals and science behind this high deformation shearing process can help to improve the tool life and blanked edge quality in various ways. Finite Element Modeling of the blanking process along with experimental testing is used in this study to study the influence of various process parameters on punch and die life and blanked edge quality. In high volume blanking and blanking of high strength materials, improving the tool life can save not only tool material but also change over time which can take up to a few hours for every change over. The interaction between punch, stripper plate and sheet material is first studied experimentally since a fundamental understanding of the behavior of these components at different blanking speeds is very essential to design robust tooling for high speeds. A methodology is developed using the experimentally obtained blanking load and FEM of blanking to obtain flow stress data of the sheet material at high strains and strain rates. This flow stress data is used to investigate the effects of various process parameters on tool stress and blanked edge quality.

New formulations are essential to fit the needs of manufacturing printed circuit boards and semiconductors. Copper electrolytes for high throwing power applications with high thermal reliability and high throughput are becoming extremely important for manufacturing high aspect ratio circuit boards. Here we discuss innovative DC copper metallization formulations for hoist lines and VCP (Vertical Continues Plating) applications with high thermal reliability and throughput for high aspect ratio PCB manufacturing. The formula has a wide range of operation for current density. Most importantly plating at high current density using this DC high throw acid copper process offers high throughput, excellent thermal reliability, and improved properties for present-day PCB manufacturing. The operating CD range is 10 – 30 ASF where microdistribution of ≥ 85 % for AR 8:1 is achievable. This formulation offers bright ductile deposits where plating parameters are optimized for improved micro-distribution and the properties of the plated Cu deposit such as tensile strength and elongation. The thermal reliability and properties of the deposits were examined at different bath ages. Measured properties are Elongation ≥ 18% and tensile strength ≥ 40,000 psi.

  • Sheet Metal Forming Introduction Sheet Metal Is Simply Metal Formed Into Thin and Flat Pieces
    www.getmyuni.com Sheet Metal Forming Introduction Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. Metal Forming Process Forming can be defined as the process in which the desired size and shape of the object are obtained through plastic deformation of material. The stresses induced during the process are greater than yield strength but should be less than the fracture strength. Different types of loading may be used depending on the process. Tensile Compressive Shear Bending Classification of Metal Working Process Metal working process may be classified as the ease with which metal may be formed into useful shapes by- Plastic deformation process Metal removal process a) PLASTIC DEFORMATION PROCESS In this the volume and the mass of the metal are conserved and the metal is displaced from one location to another. b) METAL REMOVAL PROCESS In this the material is removed from the stock in order to give it required shape. Classification of Metal Forming Process Metal forming process may be classified on the basis of type of forces applied to the work piece as it is formed into direct shape. www.getmyuni.com Direct compression type process These categories are: (e.g.-Forging, Rolling) 1) Direct – compression – type process Indirect compression process 2) Indirect – compression processes (e.g.-Extrusion, Wire Drawing) 3) Tension type processes Tension type process 4) Bending processes (e.g.-Stretch forming) 5) Shearing processes Bending process Shearing process Sheet metal processing The raw material for sheet metal manufacturing processes is the output of the rolling process.

    MODULE 3 FORGING UPSET FORGING Open Die forging Impression/Closed Die forging Flashless / Precision forging STANDARD TERMINOLOGY FORGING – OPERATIONS AND CLASSIFICATIONS Forging is a metal working process in which useful shape is obtained in solid state by hammering or pressing metal. 1. Upsetting 2. Edging Ends of the bar are shaped to requirement using edging dies. 3. Fullering Cross sectional area of the work reduces as metal flows outward, away from centre 4. Drawing Cross sectional area of the work is reduced with corresponding increase in length using convex dies. 5. Swaging Cross sectional area of the bar is reduced using concave dies. 6. Piercing Metal flows around the die cavity as a moving die pierces the metal. 7. Punching It is a cutting operation in which a required hole is produced using a punching die. 8. Bending: The metal is bent around a die/anvil. Roll forging In this process, the bar stock is reduced in cross-section or undergoes change in cross-section when it is passed through a pair of grooved rolls made of die steel. This process serves as the initial processing step for forging of parts such as connecting rod, crank shaft etc. A particular type of roll forging called skew rolling is used for making spherical balls for ball bearings SKEW ROLLING Cogging Successively reducing the thickness of a bar with open die forging • Also called drawing out • Reducing the thickness of a long section of a bar without excessive forces or machining Forging between two shaped dies • Fullering and Edging distribute material into

    MANUFACTURINGMANUFACTURING PROCESSESPROCESSES - AMEM 201 – Lecture 5 : Sheet Metal Cutting & Forming Processes DR. SOTIRIS L. OMIROU Sheet Metal Cutting & Forming Processes - General - The raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. Therefore the first step in any sheet metal process is to cut the correct shape and sized ‘blank’ from larger sheet. 2 1 Sheet Metal Cutting & Forming Processes - General - Sheet metal processing is an important process for many industries, producing home appliances (fridge, washer, dryer, vacuum cleaners etc.), electronics (DVD- and CD-players, stereos, radios, amplifiers etc.), toys and PC’s. Most of these products have metal casings that are made by cutting and bending sheet metal. We look at some of the basic sheet metal cutting and forming processes. 3 Sheet Metal Cutting & Forming Processes Definition The operations are performed on relatively thin sheets of metal: Thickness of sheet metal = 0.4 mm to 6 mm Thickness of plate stock > 6 mm Operations usually performed as cold working 4 2 Advantages of Sheet Metal Parts High strength Good dimensional accuracy Good surface finish Relatively low cost Economical mass production for large quantities 5 Sheet Metal Cutting & Forming Processes Classification 1. Cutting Operations 2. Bending Operations 3. Drawing 6 3 Basic Types of Sheet Metal Processes 1.
