RISIso-phote Based Tool-path Generation for Machining Free-form Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a novel approach for generating efficient tool paths in machining free-form surfaces. Concept of iso-phote is used to facilitate tool-path generation. An iso-phote is defined ...
Generation of Identical Noncircular Pitch Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper the theory and algorithm for generating pairs of identical noncircular conjugate pitch curves are presented. A set of criteria for two identical rigid bodies engaging in conjugate ...
A Boundary-Blending Method for the Parametrization of 2D Surfaces With Highly Irregular Boundaries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper three methods are used to generate boundary-conformed parametrization of 2D surfaces. They include two conventional approaches, the Coons method and the Laplace method, and a new ...
A Geometric Approach for Determining Exact Point Accessibility of Robotic Manipulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method of determining the exact point accessibility for an articulated manipulator with joint limits in both the regional and wrist structures. The method is based on the ...
Involute-Based Screw Driver Profiles With High Load Capacity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, involute profiles are used for the design of screw driver and screw heads instead of traditional straight line profiles to increase their load capacity and durability. New screw ...
Boundary Conformed Toolpath Generation via Laplace Based Parametric Redistribution Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new approach for boundary conformed toolpath generation is presented in this paper. The approach combines the numerical Laplace solution for initial parametrization and a parametric redistribution ...
Flowrate Formulation of Deviation Function Based Gerotor Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper derives formulas for evaluating the flowrate of gerotor pumps. The flowrate formulas are based on a deviation function, and the pitch and generating curves can be circular or ...
Rotor Profiles Synthesis for Lobe Pumps With Given Flow Rate Functions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we present a complete synthesis procedure for lobe pumps with required flow rate functions. A dimensionless flow rate expression, called the “specific flow rate,” is used for our ...
A New Gerotor Design Method With Switch Angle Assignability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gerotor is generated by an oval shape generating curve, which is attached to a large pitch circle rolling on an inside smaller one. For gerotor design, existing methods are able to handle ...
