5-Axis machining has been widely used in manufacturing of complex ruled geometries in automobile, aerospace, energy, and mould industries. Compared with traditional 3-axis machining, this machining operation offers better shaping capability and productivity with additional degrees of freedom in the tool motion. Tool path planning is a challenging task in most 5-axis machining operations, with t...

A virtual reality machine shop environment was developed for the determination of critical quantitative and qualitative machining process parameters. Material removal and milling machine axes kinematics are simulated in real time. The G-Code program serves as the input to the system. A graphical model for the calculation of quantitative data affecting the machined surface roughness was develope...

The present technology commonly uses manually operated devices to cut the grass, creating pollution and energy loss. In this project, we introduce automatic grass cutter for cutting grass. Automatic can able decrease workload of grasses in field; also this, operating force is given by rechargeable battery that fixed cutter, sensors, crane mechanism find out unwanted things get around while oper...

The paper presents the cutting by generating of spur gears using a rack cutter with modified geometry. In order to find geometry new gears, proper programme has been developed. this gear is compared one same parameters but obtained standard cutter. differences between two are insignificant tool simpler and higher durability.

Presented in this paper is a new approach to 5-axis CNC tool path generation for sculptured surface machining with a flat-end cutter. Rational Bézier and B-spline motions are used to plan cutter motions so that an exact representation of the effective cutting shape can be obtained. The exact representation leads to an accurate computation of the scallop curve generated by two adjacent tool path...

This paper proposes a novel method for generation of optimized tool path in 5-axis flank milling of ruled surfaces based on Particle Swarm Optimization (PSO). The 3D geometric problem, tool path generation, is transformed into a mathematical programming task with the machined surface error as the objective function in the optimization. This approach overcomes the limitation of greedy planning m...

In this paper, we present a method to produce analog records with vector graphics software and two different types of cutting machines: laser cutter, and paper cutter. The method enables us to engrave a variety of wave forms on a surface of diverse materials such as paper, wood, acrylic, and leather without or with prior acoustic information. The results could be played as analog records with s...
