    DRAFT – Subject to NIST approval 1.5 IMPACTS OF AUTOMATION ON PRECISION1 M. Alkan Donmez and Johannes A. Soons Manufacturing Engineering Laboratory National Institute of Standards and Technology Gaithersburg, MD 20899 ABSTRACT Automation has significant impacts on the economy and the development and use of technology. In this section, the impacts of automation on precision, which directly influences science, technology, and the economy, are discussed. As automation enables improved precision, precision also improves automation. Followed by the definition of precision and the factors affecting precision, the relationship between precision and automation is described. This section concludes with specific examples of how automation has improved the precision of manufacturing processes and manufactured products over the last decades. 1.5.1 What is precision Precision is the closeness of agreement between a series of individual measurements, values, or results. For a manufacturing process, precision describes how well the process is capable of producing products with identical properties. The properties of interest can be the dimensions of the product, its shape, surface finish, color, weight, etc. For a device or instrument, precision describes the invariance of its output when operated with the same set of inputs. Measurement precision is defined by the International Vocabulary of Metrology [1] as the "closeness of agreement between indications obtained by replicate measurements on the same or similar objects under specified conditions." In this definition, the "specified conditions" describe whether precision is associated with the repeatability or the reproducibility of the measurement process. Repeatability is the closeness of the agreement between results of successive measurements of the same quantity carried out under the same conditions.

Evaluation of the Rheological Behavior of a Semi-Solid Al–SiC Composite using a Parallel-Plate Drop-Forge Viscometer. International Journal of Materials Science and Applications. Vol. 3, No. 6, 2014, pp. 344-352. doi: 10.11648/j.ijmsa.20140306.21 Abstract: This paper presents of studies performed to assess the effect of rheological behavior on the near-net shape forming of an Al–20 vol% SiC composite of Duralcan F3A.20S and of the mother aluminum alloy A356 for comparison. Isothermal experiments were conducted using results of a parallel-plate drop-forge viscometer in a temperature range from 849 K (576 ºC) to 862 K (590 ºC). Each experiment indicated that the viscosity decreased in the early increasing shear rate stage and subsequently increased with decreasing shear rate. The overall relationship between the viscosity, µ [Pa .s], and the shear rate, γɺ [s -1], can be described by a power-law model of µ = 3.2 × 10 7 γɺ -1.5 for Duralcan and µ = 1.6 × 10 7γɺ -1.5 for A356.

It has been accepted for inclusion in University of Kentucky Master's Theses by an authorized administrator of UKnowledge. For more information, please contact [email protected]. ABSTRACT OF THESIS FRICTION STIR PROCESSING OF ALUMINUM ALLOYS Friction stir processing (FSP) is one of the new and promising thermomechanical processing techniques that alters the microstructural and mechanical properties of the material in single pass to achieve maximum performance with low production cost in less time using a simple and inexpensive tool. Preliminary studies of different FS processed alloys report the processed zone to contain fine grained, homogeneous and equiaxed microstructure. Several studies have been conducted to optimize the process and relate various process parameters like rotational and translational speeds to resulting microstructure. But there is only a little data reported on the effect of the process parameters on the forces generated during processing, and the resulting microstructure of aluminum alloys especially AA5052 which is a potential superplastic alloy. In the present work, sheets of aluminum alloys were friction stir processed under various combinations of rotational and translational speeds.

The 90° indexing fixture accepts the Matrix pallet and drawbar from System 3R. The pallets can be either manually loaded and indexed or integrated to a fully automated manufacturing cell. The following options are available for mounting of the workpiece Directly to Matrix pallet. To a reference system. To a manual vise. To a magnetic chuck. Mounting directly to Matrix Pallet The workpiece can be mounted directly to the Matrix pallet (approx 5” diameter) utilizing a series of predrilled holes. The pallet is also available in a 6” automation ready version which allows for custom hole layouts for specific applications. Larger sub-plates are easily implemented for custom mounting, jigs, etc. Mounting to a Reference System Many facilities are already using System 3R, Erowa or Hirschmann referencing systems. Already mounted components can be used by mounting the preferred referencing system manual chuck to the face of the Matrix pallet. The Matrix pallet is still used for the indexing function. When the squaring procedure is finished, the pre- mounted components can be moved to the next process. Mounting to a Manual Vise Two styles of manual vises apply themselves well to SquareTech Self Centering Precision toolmaker The self centering style of vise has many jaw options available to satisfy various part geometries.

    metals Article Friction Drilling of Difficult-to-Machine Materials: Workpiece Microstructural Alterations and Tool Wear Shayan Dehghan * , Mohd Idris Shah b. Ismail * , Mohd Khairol Anuar b. Mohd Ariffin and B. T. Hang Tuah b. Baharudin Department of Mechanical and Manufacturing Engineering, Faculty of Engineering, Universiti Putra Malaysia, UPM Serdang 43400, Selangor, Malaysia * Correspondence: [email protected] (S.D.); [email protected] (M.I.S.b.I.) Received: 3 July 2019; Accepted: 23 July 2019; Published: 29 August 2019 Abstract: Difficult-to-machine materials are metals that have great toughness, high work-hardening, and low thermal conductivity. Friction drilling of difficult-to-machine materials is a technically challenging task due to the difficulty of friction drilling, leading to excessive tool wear, which adversely affects surface integrity and product performance. In the present study, the microstructural changes of workpieces and tool wear for friction drilling of AISI304, Ti-6Al-4V, and Inconel718 are characterized. It helps to have an in-depth understanding of heat generation mechanics by friction and the mechanism of the friction drilling process. The study contributes to providing an enhanced microstructural characterization of workpiece and tool conditions, which identifies the material behavior and shows how it affects the bushing formation quality and drilling tool performance. The results reveal that the abrasive wear is mostly observed in the conical region of the tool, which has maximum contact with hole-wall. Moreover, the low thermal conductivity of Ti-6Al-4V increases frictional heat generation severely, and reduces product quality and tool life subsequently.
