V-Shaped Microgrooving with Two Flat-Ends by 6-axis Control Machining

Advanced Control Technologies for 5-Axis Machining

Demand for 5-axis machine tools has grown rapidly with the appearance of high-performance machines and growing requirements for high-efficiency to enhance competitiveness. To meet market needs, FANUC provides innovative CNCs, including the FS30i-A and FS31i-A5, that control up to 24 axes simultaneously with maximum paths of 10 enabling high-speed and high-precision multiple-axis and path contro...

Tractrix-based tool orientation control for 5-axis CNC machining

We consider a 5-axis CNC machine whose tool axis maintains a fixed angle with respect to the surface normal as the machine tool cuts a given path on a smooth surface. The tool axis a(ξ) lies on a cone of constant angle ψ about the surface normal n(ξ) at each point of the path, but its azimuthal position on this cone remains indeterminate. Geometrically speaking, given a curve n(ξ) on the unit s...

Highly effective way in five-axis sculptured surfaces machining using flat-end cutter

Abstract: This paper applied the concept of “contact” in Differential Geometry into the machining of the sculptured surface. I presented the contact principle of the machining of complicated surfaces, using the circumference circle of the cylindrical cutter to sweep the curved surface instead of ball-end mill. This is highly effective method. In this paper an theory for machining complicated su...

Surface swept by a toroidal cutter during 5-axis machining

This paper presents a method of determining the shape of the surface swept by a tool that follows a 5-axis tool path for machining curved surfaces. The method is based on discretizing the tool into pseudoinserts and identifying imprint points using a modified principle of silhouettes. An imprint point exists for each pseudo-insert, and the piecewise linear curve connecting them forms an imprint...
