A Microcomputer Controlled Contouring Machine, Kripaker K. Punja
Retrospective Theses and Dissertations
An Apple microcomputer and a three axis milling machine are the basis for a CAD/CAM system with the capability of drilling and contour milling operations. The milling machine axes are driven by three stepper motors under the control of the Apple microcomputer and the ISAAC data acquisition module. An interactive part design program using high resolution color graphics has been developed. It employs lines, circles and points to define the geometry for the part. The design is entered at the CRT and stored as a CAM database on the user disc. Once the design is complete it is postprocessed and …

Interactive Computer Aided Design And Animation Of Spatial Mechanisms, Emmet B. Peter
Retrospective Theses and Dissertations
The synthesis of planar and spatial mechanisms is often accomplished by either trial and error supplemented by computer analysis or by specific analytical techniques in the literature. In either case it is extremely helpful to be able to visualize a physical design as it emerges, and to see a graphic display of it in animated motion. This paper describes the development of a general interactive program for both analyzing and viewing a spatial 4-bar (RSSR) mechanism in animated motion. The analysis provides complete position, velocity, and acceleration information and, for the special case of the planar 4-bar, the same information …
The Development Of A Computer Aided Design Program For Constant Group Delay Monolithic Crystal Filters, Michael A. Robitaille
The Development Of A Computer Aided Design Program For Constant Group Delay Monolithic Crystal Filters, Michael A. Robitaille
Retrospective Theses and Dissertations
A computer program, which realizes monolithic crystal filters with constant group delay, is developed. This program analyzes and synthesizes a class of transfer functions developed by J.D. Rhodes called equidistant linear phase transfer functions. Using cascade synthesis, the program calculates the values of the inductor and capacitors of the ladder sections which realizes these functions. The ladder sections are implemented using monolithic crystal filters.
