5-Axis tool path planning based on highly parallel discrete volumetric geometry representation: Part I contact point generation

Abstract

Impact of decisions in the design process is initially high and declines as the design matures. However, few computational tools are available for the early design phase, thus an opportunity exists to create such tools. New technology opens up new possibilities to create new and novel computational tools. In this work an existing application is adapted for a new novel 3D input device that is named the Leap Motion controller. The controller allows the user to interact with 3D objects on the screen by using fingers and hands. The of result of this work is a conceptual design application which enables very direct manipulation of 3D objects on the screen, which has not before been achieved for this type of application in 3D. An improved human-computer interaction can potentially improve the users understanding of the structural behavior of a model, cognitive engagement in the design task, and encourage further design exploration. Three different cases are implemented which aims to enable the user to explore different design options with emphasis on geometrical form, as this has the greatest potential to improve the structural performance. The case studies demonstrate new potential for building engineering intuition and improving design space exploration through very direct manipulation in 3D.

Direct Digital Subtractive Manufacturing of a Functional Assembly Using Voxel-Based Models

“…Following the procedure described in Ref. [43], known as the 3D contour offset approach, convolution of a spherical SE with the surface of the contact volume along a starting contour will produce a tube whose radius is determined from the desired radial stepover for the toolpath. The intersection curve where the tube meets the surface of the contact volume can then be used as the successive contour along which to perform another offset with the same SE.…”

Remarkable Characteristics of a Novel Path Interval Determination in Filleted End Milling

“…It is unquestionable that computer-aided design (CAD) plays an important role in creative process of various products [10]. Product manufacturing with CNC machine tools is practically conducted based on a designed shape constructed in CAD, and the process planning is arranged using computer-aided manufacturing (CAM) [11,12]. The machine movement produced by CAM has great influence on surface quality, machining efficiency, etc.…”

Study on Tool Condition Parameters Intended for Smart Tool Management in Filleted End Milling

“…A designed shape made in computer-aided design has indispensable influence on product manufacturing. Computer-aided manufacturing is also a crucial technology for the modern production [21,22]. A process plan with machining parameters' selection in computer-aided manufacturing is vital for surface quality, machining accuracy, etc.…”
