Abstract: Methodical specification of process inputs for injection molding is hindered by the absence of accurate analytical models. For these processes, the input variables are assigned either by trial ...

Abstract: This paper proposes a dynamic state model of tool wear. This model is developed for the design of an adaptive observer which is used for on-line tool wear sensing in turning based on force ...

Abstract: An improved model for force transients in turning is introduced to incorporate the geometry of the cut, as well as plowing at the cutting edge and rubbing of the flank wear land against the ...

Abstract: Modeling uncertainty in machining, caused by modeling inaccuracy, noise and process time-variability due to tool wear, hinders application of traditional optimization to minimize cost or production ...

Abstract: A method is presented for identifying the chip formation, plowing, and sliding forces in turning from force transients. For this purpose, a simple model is used which separates the cutting ...

Abstract: Fault detection of a helicopter gearbox by pattern classification is discussed. The detection system is composed of two components, a quantization matrix to flag the measurements, and a multi-valued ...

Abstract: A new method of diagnosis is introduced for helicopter gearboxes that relies on the knowledge of the gearbox “structure” and characteristics of the “features” of vibration for component fault ...

Abstract: This paper presents the experimental evaluation of the Structure-Based Connectionist Network (SBCN) fault diagnostic system introduced in the preceding article (Jammu et al, 1998). For this, ...
