An Adaptive Pressbrake Control for Strain-Hardening Materials
(The American Society of Mechanical Engineers (ASME), 1986)An improved adaptive pressbrake control algorithm is described. The problem is to control the punch reversal position of the press so that the final unloaded angle of the bend remains unchanged ... -
Measuring Tool-Chip Interface Temperatures
(The American Society of Mechanical Engineers (ASME), 1986)A two-color pyrometer was developed for monitoring the surface temperature of metal chips formed during high-speed machining processes. Optical access to the tool-chip interface was obtained by ... -
Geometric Representation of Translational Swept Volumes and its Applications
(The American Society of Mechanical Engineers (ASME), 1986)This paper presents a method for representing the geometries of translational swept volumes of three-dimensional objects which can be constructed by the union of three types of primitive objects: ... -
Wheel-Rail Wear and Adhesion With and Without Sand for a North American Locomotive
(The American Society of Mechanical Engineers (ASME), 1986)A systematic laboratory investigation, of the effect of sanding on wheel/rail wear and adhesion, is reported. The tests were conducted on the IIT-GMEMD Wheel Rail Simulation Facility, using ... -
On Shear Instability in Machining a Nickel-Iron Base Superalloy
(The American Society of Mechanical Engineers (ASME), 1986)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 ... -
Analysis of Core Fracture in Drawing of Bimetal Rods and Wires
(The American Society of Mechanical Engineers (ASME), 1986)A criterion for the prevention of core fracture during drawing of bimetal wire is proposed. In order to account for the contrary effect of friction between codrawing and coextrusion on the ... -
A Search Algorithm for the Bicriterion Group Technology Machine Loading and Product Mix Problem
(The American Society of Mechanical Engineers (ASME), 1986)The bicriterion machine loading and product mix problem in a Group Technology (GT) setting is the key to improving production output and cost and involves the primary objective of maximizing ... -
Cutting Process Dynamics Simulation for Machine Tool Structure Design
(The American Society of Mechanical Engineers (ASME), 1986)A methodology to simulate the real cutting process dynamics using a finite element structural model and a mechanistic face milling force model is proposed. While the finite element structural ... -
On the Doubly Regenerative Stability of a Grinder: The Theory of Chatter Growth
(The American Society of Mechanical Engineers (ASME), 1986)A mathematical method is devised to solve for the growth of chatter in grinders. The chatter growth rate is important because the grinding process is generally unstable. As such there is a ... -
On the Doubly Regenerative Stability of a Grinder: The Mathematical Analysis of Chatter Growth
(The American Society of Mechanical Engineers (ASME), 1986)The growth of doubly regenerative chatter in a typical plunge cylindrical grinder is analyzed. The work is based on the mathematical method developed in reference [1]. Throughout, the physics ... -
Dynamics of High-Speed Milling
(The American Society of Mechanical Engineers (ASME), 1986)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 ... -
A Crack Detection Technique for Use With Brittle Materials
(The American Society of Mechanical Engineers (ASME), 1986)Crack gages are sensors designed to monitor crack initiation and growth in engineering structures by alteration of electrical conductance. Present gages involve a thick (5 μm) metal foil on an ... -
Criterion for the Prevention of Sleeve Fracture During Extrusion of Bimetal Rods
(The American Society of Mechanical Engineers (ASME), 1986)In conjunction with the previous analysis on core fracture [1, 2], a criterion for prevention of sleeve fracture in extrusion of bimetal rods is developed. The sleeve fracture is likewise ... -
Optimal Continuous Path Planning for Seven-Degrees-of-Freedom Robots
(The American Society of Mechanical Engineers (ASME), 1986)The paper addresses the problem of end effector trajectory planning and control of seven degrees of freedom (DOF) kinematically redundant robots. An off-line optimal continuous path planning ... -
Time Series Control Charts for Correlated and Contaminated Data
(The American Society of Mechanical Engineers (ASME), 1986)This paper discusses the development of control charts for correlated and contaminated data. For illustration the charts were applied to a set of maximum principal-stress data at two locations ... -
