Real-time Variable Feedrate Parametric Interpolator for Cnc Machining
In modern commercial CAD and systems, a wide variety of part shapes for dies and molds are usually represented in parametric curves (or surfaces) like the Bezier curve, B-spline, and NURBS. However, conventional CNC machines only provide line or circular interpolators. In order to perform the machining of molds, the shapes and desired tool paths designed using CAD/CAM systems are typically appr...
متن کاملAn iterative feedrate optimization method for real-time NURBS interpolator
Non-uniform rational B-spline (NURBS) interpolator has been widely used in modern manufacturing systems to machine arbitrary geometries with great relief of the data flow bottleneck and feedrate fluctuation. However, in practice, real-time feedrate does not always meet the computer numerical control (CNC) command exactly subject to the system dynamics. To solve this problem, we present a real-t...
متن کاملToolpath Feedrate Optimization: A Case Study
The goal of this research is to improve the productivity of Numerically Controlled (NC) machine tools by optimization of feedrate settings. In this paper we compare the maximum cutting forces and cutting times using traditional methods with those achieved using the optimization methods developed in our research. Results indicate that significant productivity gains can be realized using the feed...
متن کاملThe feedrate scheduling of NURBS interpolator for CNC machine tools
This paper proposes an off-line feedrate scheduling method of CNC machines constrained by chord tolerance, acceleration and jerk limitations. The off-line process for curve scanning and feedrate scheduling is realized as a pre-processor, which releases the computational burden in real-time task. The proposed method first scans a non-uniform rational B-spline (NURBS) curve and finds out the cruc...
متن کاملEfficient Algorithm for Time-optimal Feedrate Planning and Smoothing with Confined Chord Error and Acceleration
In this paper, an efficient algorithm is proposed to generate a smooth near-timeoptimal feedrate function along a parametric tool path for 3-axis CNC machining under a feedrate bound, an acceleration bound for each axis, and a chord error bound. The algorithm first gives a discrete and computationally efficient algorithm to find a sequence of globally optimal velocity points under the feedrate,...
