The authors have investigated the structure of cutting seams obtained after steel 09G2S with a new narrow-jet plasma torch PMVR-5.3 type which has number design features in gas dynamic stabilization system (GDS) arc. To increase efficiency GDS torch, symmetrical input plasma-forming (PFG) into flow division and gas-dynamic stabilizer using two (forming stabilizing) swirlers variable swirl chann...
the implementation of different silvicultural systems can be effective on different characteristics of forest stands, such as stand structure and diameter distribution of trees. this study was carried out in shafaroud forests of gilan province of northern iran. the objectives of this research were 1) to evaluate the suitability of different probability distribution functions, including weibull,...
This paper presents the results obtained by INMA Bucharest, following a research project, in which technology for harvesting and storing industrial hemp was developed. The equipment green stalks intended this tested an experimental plot grown with Dacia - Secuieni hemp. Operating indices (actual torque at power take-off, traction force drawbar, total effective to operate equipment, working spee...
The cutting path problem for CNC sheet metal equipment is considered in this article. method of multi-contour application described solving Cutting Path Problem (CPP). to be combine contours «blocks» (groups) and several performed by using special techniques (common cut, «chained» cutting) order reduce values tool length number piercings compared with standard technique (where only idle minimiz...
Introduction: Flammable dust particles when dispersed in air under certain conditions there is a risk of explosion. The aim of this study is determine the concentration of explosive dust, and the explosion risk assessment, in some a high risk industries of shahroud. Methods: To determine the level of dust in factories investigated, sampling and determine the concentration based on the method...
Now a days the general manufacturing problem can be described as the achievement of a predefined product quality with given equipment, cost and time constraints. There is a rapid development in the quality of advanced aero space materials like aluminum and its alloys with improved properties. The difficulties in machining of these materials economically and effectively are limiting their applic...
-One critical area in automation for commercial deboning systems for meat processing, is the inability of existing equipment to adapt to varying sizes and shapes of products. This usually results in less than desirable outcomes when measured in terms of yield of the operations. In poultry processing for example, the initial cut of wing-shoulder joints is the most critical step in the deboning p...
The main objective of this work is to develop a mathematical model to evaluate optimum sanding conditions of Europen black pine (Pinus nigra). Samples were sanded using different of grit size, feed rate, cutting speed and depth of cut. Average surface roughness (Ra) values of each type of specimens were measured employing a stylus type of equipment. Interaction between sanding parameters and su...
