32	A Geometry-Based Motion Planner for Direct Machining and Control Cheatham, Robert M. 13 July 2007 (has links) (PDF) Direct Machining And Control (DMAC) is a new method of controlling machine tools directly from process planning software. A motion planning module is developed for the DMAC system that operates directly off path geometry without pre-tessellation. The motion planner is developed with the intent to process Bezier curves. The motion planning module includes a deterministic predictor-corrector-type curve interpolator, a dynamics limiting module, and a two-pass jerk-limited speed profiling algorithm. The methods are verified by machining an automotive surface in a clay medium and evaluating the resultant machine dynamics, feed rate, and chordal error throughout the machining process. motion planning motion planner motion profile constant speed parametric interpolator predictor-corrector parametric machining speed profile dynamics NURBS Bezier jerk-limited machine control DMAC direct control CNC machining Mechanical Engineering
33	Vytvoření interaktivních pomůcek z oblasti 2D počítačové grafiky / Teaching aids for 2D computer graphics Malina, Jakub January 2013 (has links) In this master’s thesis we focus on the basic properties of computer curves and their practical applicability. We explain how the curve can be understood in general, what are polynomial curves and their composing possibilities. Then we focus on the description of Bezier curves, especially the Bezier cubic. We discuss in more detail some of fundamental algorithms that are used for modelling these curves on computers and then we will show their practical interpretation. Then we explain non uniform rational B-spline curves and De Boor algorithm. In the end we discuss topic rasterization of segment, thick line, circle and ellipse. The aim of master’s thesis is the creation of the set of interactive applets, simulating some of the methods and algorithm we discussed in theoretical part. This applets will help facilitate understanding and will make the teaching more effective.
