Abstract: A process model of the metal cutting process using a minimum energy input concept was formulated. The model relates the geometry of the workpiece to cutting force. Experiments in which cutting ...

Abstract: The implications of a fundamental asymmetry in the lathe turning process are considered. The asymmetry is the directional dependence of system stiffness that exists at the cutting tool edge. ...

Abstract: Residual stress distributions due to plating and polishing were determined for nickel-phosphorus plated aluminum alloy disks. Knowledge of these stresses provides insight into the material deformation ...

Abstract: The problem of describing variations in the deformation process in chip formation is considered by constructing two catastrophe theory models of the process. Shear plane chip formation models ...

Abstract: The problem of predicting changes in the chip formation process in metal cutting was considered. An analytical model which predicts the shear angle as the cutting tool approaches the end of ...

Abstract: The effects of the stress state transition from plane stress at the workpiece surface to plane strain in the central region of the chip formation zone were studied. A finite element analysis ...

Abstract: With the intent of continuously monitoring cutting tool condition in intermittent machining operations in a benign manner, a noncontacting measurement system was assembled to measure spindle shaft ...

Abstract: The measurement of tooling-workpiece interface forces is needed for process design, process modeling and analysis and process monitoring for control. One approach to measuring local interface loads ...

Abstract: Since acoustic emissions are generated by fundamental mechanical processes, they can provide insight into the basic processes which determine friction and wear behavior. Descriptions of acoustic ...

Abstract: A transducer for measuring interface loads was fabricated, characterized, and demonstrated by measuring coefficient of friction. It is composed of a segmented body supported on normal force and ...
