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.

let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...

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...
