  • Manufacturing Glossary
    MANUFACTURING GLOSSARY Aging – A change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after a hot-working operation or a heat-treatment (quench aging in ferrous alloys, natural or artificial aging in ferrous and nonferrous alloys) or after a cold-working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy. Abrasive – Garnet, emery, carborundum, aluminum oxide, silicon carbide, diamond, cubic boron nitride, or other material in various grit sizes used for grinding, lapping, polishing, honing, pressure blasting, and other operations. Each abrasive particle acts like a tiny, single-point tool that cuts a small chip; with hundreds of thousands of points doing so, high metal-removal rates are possible while providing a good finish. Abrasive Band – Diamond- or other abrasive-coated endless band fitted to a special band machine for machining hard-to-cut materials. Abrasive Belt – Abrasive-coated belt used for production finishing, deburring, and similar functions.See coated abrasive. Abrasive Cutoff Disc – Blade-like disc with abrasive particles that parts stock in a slicing motion. Abrasive Cutoff Machine, Saw – Machine that uses blade-like discs impregnated with abrasive particles to cut/part stock. See saw, sawing machine. Abrasive Flow Machining – Finishing operation for holes, inaccessible areas, or restricted passages. Done by clamping the part in a fixture, then extruding semisolid abrasive media through the passage. Often, multiple parts are loaded into a single fixture and finished simultaneously. Abrasive Machining – Various grinding, honing, lapping, and polishing operations that utilize abrasive particles to impart new shapes, improve finishes, and part stock by removing metal or other material.See grinding.

  • Centrifugal Iso-Finishing
    MECHANICAL CENTRIFUGAL ISO-FINISHING New Challenges with 3D-Printed Parts Metal parts manufactured using various additive manufac- turing technologies present a new and entirely different set of challenges for surface finishers. Unlike with conventional manufacturing technologies, additive manufacturing does not produce parts with substantial burrs, which are by-products of cutting or metal-forming operations. Printed parts also are free of the non-isotropic machining or grinding patterns common to subtractive operations that can have negative effects on part wear and fatigue resistance. In many cases, however, 3D printing does produce unaccept- ably rough surfaces on parts, and this poses severe challenges for many mechanical surface finishing methods. Sometimes the surfaces of printed parts rival those of unfinished casted parts in terms of their initial surface roughness and positive skew. High-energy finishing methods are required to produce accept- able surface finishes with process cycle times that won’t be a Centrifugal iso-finishing can produce very refined surface source of bottlenecks or production constraints. finishes on parts in abbreviated process cycle times. (Image courtesy of Cole Mathisen, MFI.) A High-Speed, High-Energy Alternative Centrifugal iso-finishing is a high-speed and high-intensity mass finishing method in which abrasive or polishing mate- rials are caused to interact with part edges and surfaces with 10 times the surface pressure of low-energy finishing methods. What this means, in practical terms, is that it is possible to produce very refined surface finishes in abbre- viated process cycle times. It also means that parts with complex and detailed geometries can be deburred with a minimum of manual intervention.

  • Critical Mass
    Critical Mass By Dr. LaRoux K. Gillespie Courtesy of Rosler Metal Finishing USA A six-load, centrifugal disc mass-finishing system from Rosler features automatic loading and auto screening. Mass finishing parts at the machining center offers economic advantages. There are major economic and scheduling advantages to having a part come off a machining center complete. Most machinists think parts are finished at this point because part dimensions are correct. However, they forget that most parts must be deburred, cleaned, weighed or counted and then packaged before shipping. In most shops, that involves moving the machined parts to another part of the shop, putting them on shelves and eventually having someone perform the final operations prior to shipment. Done at the Machine Deburring parts at the machine means that they are truly ready to ship. Joe Gaser, vice president of Osborn International, Cleveland, a manufacturer of industrial brushes and surface finishing tools, noted that manufacturers would obviously like to receive payment for their parts earlier than they do. His solution: “Finish your parts at the machine instead of having them sit for days or weeks waiting to be deburred.” There are other benefits to finishing parts at a machining center. Shops find and fix problems earlier, better understand the impact of keeping burrs small, prevent mistakes from using the wrong finishing process, do not lose parts, and possibly prevent oils from drying on parts, which makes the oils difficult to remove. In addition, one person is responsible for the completed part. There are three major ways of producing a burr-free part at the machine: preventing and minimizing burrs, brush deburring during the machine cycle, and cellular manufacturing that includes deburring.

  • Design Process Control for Improved Surface Finish of Metal Additive Manufactured Parts of Complex Build Geometry
    inventions Article Design Process Control for Improved Surface Finish of Metal Additive Manufactured Parts of Complex Build Geometry Mikdam Jamal 1 and Michael N. Morgan 2,* ID 1 The Manufacturing Technology Centre Ltd., Ansty Park, Coventry CV7 9JU, UK; [email protected] 2 Advanced Manufacturing Technology Research Laboratory (AMTREL), Faculty of Engineering and Technology (FET), Liverpool John Moores University, Liverpool L3 3AF, UK * Correspondence: [email protected]; Tel.: +44-(0)151-2312590 Received: 11 August 2017; Accepted: 6 December 2017; Published: 13 December 2017 Abstract: Metal additive manufacturing (AM) is increasingly used to create complex 3D components at near net shape. However, the surface finish (SF) of the metal AM part is uneven, with surface roughness being variable over the facets of the design. Standard post-processing methods such as grinding and linishing often meet with major challenges in finishing parts of complex shape. This paper reports on research that demonstrated that mass finishing (MF) processes are able to deliver high-quality surface finishes (Ra and Sa) on AM-generated parts of a relatively complex geometry (both internal features and external facets) under select conditions. Four processes were studied in this work: stream finishing, high-energy (HE) centrifuge, drag finishing and disc finishing. Optimisation of the drag finishing process was then studied using a structured design of experiments (DOE). The effects of a range of finishing parameters were evaluated and optimal parameters and conditions were determined. The study established that the proposed method can be successfully applied in drag finishing to optimise the surface roughness in an industrial application and that it is an economical way of obtaining the maximum amount of information in a short period of time with a small number of tests.
