RISMachining and Grinding: A Historical Review of the Classical Papers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Major contributions to machining and grinding research in the US came in the twentieth century. The seminal work by Frederick Winslow Taylor on the Art of Cutting Metals published in 1907 was ...
The Ledge Tool: A New Cutting Tool Insert
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The salient features of a simple, wear-tolerant cemented carbide tool are described. Results are presented for high-speed machining (3 to 5 times the conventional speeds) of titanium alloys in ...
Finishing of Silicon Nitride Balls for High-Speed Bearing Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A batch of 12, HIP’ed silicon nitride (Si3 N4 ) balls (NBD 200 from CERBEC) of 13.4 mm nominal diameter were finished by magnetic float polishing (MFP) process. These balls contained a large ...
Attritious Wear of Silicon Carbide
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Attritious wear of silicon carbide in simulated grinding tests against a cobalt base superalloy at high speed and extremely small feed rate was studied using a scanning electron microscope (SEM) ...
On Shear Instability in Machining a Nickel-Iron Base Superalloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The deformation in chips produced in machining a nickel-iron base superalloy (Inconel 718), at various speeds up to 213.5 m/min [700 surface feet per minute (SFPM)] has been investigated. In ...
On the Mechanics of Chip Segmentation In Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanics of chip segmentation, during machining of a cold rolled steel has been investigated from a phenomenological point of view using a high speed movie camera and an explosive quick ...
Scanning Electron Microscope Study of Surface Characteristics of Abrasive Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Scanning electron micrographs of different types of commercial abrasive grains used in grinding are discussed. Surface topography is found useful, along with other physical and chemical properties, ...
Magnetic Field Assisted Finishing of Ceramics—Part II: On the Thermal Aspects of Magnetic Float Polishing (MFP) of Ceramic Balls
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermal model developed in Part I of this three-part series is applied in this paper to magnetic float polishing (MFP) of ceramic (Si3 N4 ) balls. Using this method, the flash temperatures, ...
Magnetic Field Assisted Finishing of Ceramics—Part I: Thermal Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermal model for magnetic field assisted polishing of ceramic balls/rollers is presented. The heat source at the area of contact between the balls and the abrasives where material removal ...
Magnetic Field Assisted Finishing of Ceramics—Part III: On the Thermal Aspects of Magnetic Abrasive Finishing (MAF) of Ceramic Rollers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conditions during finishing of advanced ceramics by magnetic abrasive finishing (MAF) processes are found to be, by and large, transient. Consequently, the available quasi-steady-state solutions ...
