Temperature control during the cutting process with different parameters such as cutting velocity and applying water cooling is essential to decrease the cutting force, increase the life of the cutting tool and decrease the machined surface temperature of work-piece. In this research, the temperature of machined surface and the chip-tool interface in orthogonal cutting process of Ti-6Al-4V were...

Due to the size and material changes and the hard impurities of the cutting workpieces in the band sawing process, the load of the band saw blades changes greatly so as to easily break the blades. The load of the band saw blades in the cutting process is unbalanced so as to easily produce the deviation of the saw blade’s cutting path, even seriously affect the accuracy of the sawing. On the occ...

Abstract China is a large grain storage country, and at this stage, the effective capacity of country has exceeded 900 million tonnes. Grain subject to localized high temperatures, pests, other abnormalities during storage. Therefore, regular quality checks need be carried out on grain, cuttings are first step in carrying checks. The current domestic cutting equipment suffers from low efficienc...

to assessment alfalfa cultivars research project this research has been fulfilled in 2011 at khouzestan agricultural and natural resource research center in southwest of ahwaz in khouzestan province (iran) by position 31º20′ n, 48º40′ e. at first section for evaluation wet forage yield cultivars such as “baghdadi”, “mesasersa”, “yazdi”, “bami”, “nikshahri”, “synthetic” (main factor) and two cut...

An instantaneous rigid force model for prediction of cutting forces in ball-end milling of  sculptured surfaces is presented in this paper. A commercially available geometric engine is used to represent the cutting edge, cutter and updated part geometries. The cutter used in this work is an insert type ball-end mill. Intersecting an inclined plane with the cutter ball nose generates the cutting...

“I have heard about a young boy (4 or 5 years old) in hungary with a serious spinal cord injury eight months ago: as of my information, his spinal cord has broken between his skull and C1 totally (he is ventilator-dependent). What kind of therapies do you think, are suitable a person like him? Can we hope in some research that will help him to improve his condition? Are there any special proble...

Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, th...

Modern harvesters are equipped with measurement and bucking optimization systems able not only to continuously measure the length and diameter of the stem but also to predict the profile of the unknown part of a stem and to calculate the optimal cross-cutting points for the whole stem. So far, tree-bucking optimization in the Nordic countries has been efficiently applied only with spruce becaus...

Given the current economic climate in healthcare, cost containment has become the newest buzzword in the literature and on the lecture circuit. Cost cutting simply must be done. One of the easiest ways to show reduction in costs is to decrease the dollar amount spent on pharmaceutical supplies by the anesthesia department. Those methods of cost cutting which look at the bottom line expenditures...

With the development of power-to-gas (P2G) technology and demand-response (DR) technology, new ideas have been proposed for research into scheduling strategy integrated energy systems (IER). Focusing on wind power consumption, this paper proposes a day-ahead IER with P2G equipment, taking consideration DR. On consumption side, demand elasticity matrix is introduced to describe user’s participat...
