Grinding is one of the most widely used material removal methods at the end of many
process chains. Grinding force is related to almost all grinding parameters, which has a …

This paper presents a systematic NURBS interpolator with constant speed at feedrate-
sensitive regions under drive and contour-error constraints to generate a smooth and …

Driven by the ever increasing demand in function integration, more and more next
generation high value-added products, such as head-up displays, solar concentrators and …

Current nonuniform rational B-spline interpolating methods encounter problems pertaining
to the interpolating error, feedrate profile, and machining efficiency; the optimal feedrate …

The widespread linear five-axis tool path (G01 blocks) is usually described by two
trajectories. One trajectory describes the position of the tool tip point, and the other one …

Abstract Parametric interpolation for Non-Uniform Rational B-Spline (NURBS) curve has
become more important than ever before in the control of CNC machine tools. An effective …

Feedrate scheduling is crucial for CNC systems to generate a smooth movement which is
able to satisfy increasing requirements on machining quality and efficiency. In this paper, a …

Continuous linear commands are widely executed in computer numerical control (CNC)
machining. The tangential discontinuity at the junction of consecutive segments restricts the …

For an effective NURBS interpolator, generating the smooth feedrate profile and minimizing
the feedrate fluctuation are two main tasks, which have a great influence on the machining …

The linear motion command (G01) is a widely used command format in CNC machining.
However, the tangential direction discontinuity at the corner junction will cause velocity …
