Toolpath generation method for four-axis NC machining of helical rotor

Purpose: This paper presented a method for generating the toolpaths for the machining of a helical rotor on five-axis machine tool. Design/methodology/approach: The geometry of the helical rotor is designed based on the ruled surfaces. Through the homogeneous coordinate transformation, the cutter location of the flank milling for four-axis machining can be generated. The postprocessor are devel...

Automatic Generation of Gouge - free and Angular - velocity - compliant 5 - axis Toolpath ( Revised )

Existing works in automatic generation of interference-free 5-axis surface machining toolpaths bear a serious drawback – in order to avoid the obstacles, the tool is often required to make drastic change in its orientation between neighboring contact points. Such quick change in tool’s orientation can never be made possible in reality due to the stringent physical limit on the speed and acceler...

Toolpath generation for layer manufacturing of fractal objects

Purpose – Fractal geometry can be used to model natural objects which cannot be easily represented by the euclidean geometry. However, contemporary computer-aided design (CAD) and computer-aided manufacturing (CAM) systems cannot be used to model a fractal object efficiently. In a general layer manufacturing (LM) workflow, a model described by the euclidean geometry is required in order to gene...

A Jpeg Corner Artifact from Directed Rounding of Dct Coefficients

JPEG compression introduces a number of well known artifacts including blocking and ringing. We describe a lesser known or understood artifact consisting of a slightly darker or lighter pixel in the corner of 8×8 pixel blocks. This artifact is introduced by the directed rounding of DCT coefficients. In particular, we show that DCT coefficients that are uniformly rounded down or up (but not to t...

Optimal Trajectory Generation for a Robotic Worm via Parameterization by B-Spline Curves

In this paper we intend to generate some set of optimal trajectories according to the number of control points has been applied for parameterizing those using B-spline curves. The trajectories are used to generate an optimal locomotion gait in a crawling worm-like robot. Due to gait design considerations it is desired to minimize the required torques in a cycle of gait. Similar to caterpillars,...
