RISInterpolation and Extrapolation of Optimally Fitted Kinematic Error Model for Five-Axis Machine Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machine tool geometric errors are frequently corrected by populating compensation tables that contain position-dependent offsets to each commanded axis position. While each offset can be determined by directly measuring ...
Modeling, Analysis, and Simulation of Paste Freezing in Freeze Form Extrusion Fabrication of Thin Wall Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the freezeform extrusion fabrication (FEF) process for aqueousbased pastes, the subzero temperature (in Celsius) environment aids the part in maintaining its shape by freezing the water present in the paste. The ...
Two-Dimensional Modeling and System Identification of the Laser Metal Deposition Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) processes fabricate parts by adding material in a layer-by-layer fashion. In order to enable closed-loop process control—a major hurdle in the adoption of most AM processes—compact models suitable ...
Height Dependent Laser Metal Deposition Process Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser metal deposition (LMD) is used to construct functional parts in a layerbylayer fashion. The heat transfer from the melt region to the solid region plays a critical role in the resulting material properties and part ...
Extrusion Process Modeling for Aqueous Based Ceramic Pastes—Part 1: Constitutive Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The extrusion process for aqueousbased ceramic pastes is complex due to the nonNewtonian behavior of these pastes. In this study, the extrusion process is modeled by characterizing the ceramic paste viscosity using a ...
Extrusion Process Modeling for Aqueous Based Ceramic Pastes—Part 2: Experimental Verification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the Part 1 paper, a constitutive law for the extrusion process of aqueousbased ceramic pastes was created. In the study described herein, a capillary rheometer was used to calibrate the viscosity of an alumina paste, ...
Control-Oriented Modeling of Lithium-Ion Batteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Battery management systems (BMSs), which monitor and optimize performance while ensuring safety, require control-oriented models, i.e., models tailored to the design and implementation of estimation and control algorithms. ...
A Review of Manufacturing Process Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Smart manufacturing concepts are being integrated into all areas of manufacturing industries, from the device level (e.g., intelligent sensors) to the efficient coordination of business units. Vital components of any ...
Additive Manufacturing of Transparent Soda-Lime Glass Using a Filament-Fed Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There are many scientific and engineering applications of transparent glass including optics, communications, electronics, and hermetic seals. However, there has been minimal research toward the additive manufacturing (AM) ...
Analytical Force Modeling of Fixed Abrasive Diamond Wire Saw Machining With Application to SiC Monocrystal Wafer Processing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Free abrasive diamond wire saw machining is often used to cut hard and brittle materials, especially for wafers in the semiconductor and optoelectronics industries. Wire saws, both free and fixed abrasive, have excellent ...
