Abstract: This paper is based on previous work of the author and his associates which was published in a series of papers, mainly on those given here as references [2–6], dealing with time domain ...

Abstract: The paper deals with chipping and breakage of carbide tools and it is based on a combination of turning tests, examination of fracture surfaces, and analysis of stresses in the tool as ...

Abstract: As spindle speeds and power have increased, the possibility of using the stability lobe phenomena to substantially increase the metal removal rate has become more attractive, and selection of ...

Abstract: The paper describes a rather simple and efficient algorithm for processing the milling force signal to detect cutter breakage. Using sampling synchronized with cutter teeth the basic variation ...

Abstract: This paper compares various sensors and shows that a microphone is an excellent sensor to be used for chatter detection and control. Comparisons are made between the microphone and some other ...

Abstract: Machine tool supervision and control algorithms require reliable and effective sensor signals to operate properly. In effort to satisfy this need, a high stiffness, wide bandwidth torque sensor ...

Abstract: Tool wear is an important limiting factor in machining hardened steel. Plane milling of H13 hot work tool steel (42–46 HRC) was conducted on a three-axis machine to obtain flank wear data ...

Abstract: Drillstring vibrations cause premature failure of downhole tools and the drillstring itself. Also, drill bits do not drill efficiently as a result of these vibrations and this inefficiency causes ...

Abstract: Characteristics of a reasonably well-adjusted NC servo are given as measured as well as modeled. A model of an A/C loop is added and investigated for stability and for a transient in meeting ...
