The aim of this research is to measure the energy consumption and compare cutting performance three types battery-powered chainsaws (Stihl MSA 200, Stihl 220, 300). Tested were powered by two different battery packs AP 300 S 500 S) with capacity output current when wooden beams, European beech (Fagus sylvatica L.) black locust (Robinia pseudoacacia densities moisture content. Energy was measure...

The objective of the present study is to analyze and compare the cutting performance of segmented diamond blades when dry-cutting concrete. A cutting criteria is proposed to characterize the wear of the blades by measuring the variation of the external diameter and the weight loss of the blade. The results exhibit the cutting blade SB-A, which has twice the density of diamonds and large contact...

INTRODUCTION Recently, a milling for die using a small end mill of diameter less than 1 mm is increased, because sizes of plastic mold parts such as connectors for an IT and an electronics becomes micro extremely. In general, a tool life is long and a good cut surface is obtained as a cutting speed is high. A speed-increasing spindle, which is attached to a shank may be used to increase the cut...

This work presents a hybrid approach based on the use of genetic algorithms to solve efficiently the problem of cutting structural beams arising in a local metalwork company. The problem belongs to the class of onedimensional multiple stock sizes cutting stock problem, namely 1dimensional multiple stock sizes cutting stock problem. The proposed approach handles overproduction and underproductio...

This paper studies micro structure fabrication by means of a textured tool cutting edge, which is manufactured by applying the wire cut electrical discharge machining (WEDM). Machining performance of the square structure fabrication on the tool cutting edge is investigated in the WEDM process, and the machining accuracy is explored in experimental analyses. In this proposed method, undesired ov...

We propose an efficient algorithm for compressing cutting plane of three dimensional Computational Fluid Dynamics (CFD) data set. Observing the cutting planes of large 3D CFD data set is an important method for examination of simulation result, and efficient compression algorithm of these cutting planes is important for good performance of visualization when the simulation is running in a remot...
