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...

Incomplete mesh offset for NC machining

In this paper, the incomplete triangular mesh including reversed faces and gaps between boundary edges is directly offset for NC machining. or three-axis machining, vertical faces are deleted and the face normal vectors directing the lower part of model are changed to upward. The omplete mesh is offset by the multiple normal vectors of a vertex, and boundary edges and boundary vertices are offs...

Design and Machining Control via Interoperable Function Blocks and STEP-NC Data Model

This paper discussed about proposes an architecture and implementation of a controller via Function Block Development Kit (FBDK). It can be used to create an open CNC architecture on ISO 14649 and Function Block (IEC 61499). This offers interoperability, portability, and adaptability. The system framework consists of three main components: (1) STEP-NC Parser, (2) Tool Path Simulator, and (3) Co...

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...
