In this work, genetic algorithm (GA) technique was applied to investigate cutting process parameters influence on workpiece price formation using the concepts of contribution margin. The is one most important processes among many others available in manufacturing scenarios. Nevertheless, it common find some manufactured item, or at least part it, that made, by process. Because its importance, studies related optimization were performed, and last years, task has been explored different...

Machining hardened steel has been a recurring issue in the literature when tools with defined geometry cutting edges are used. It is well known use of cemented carbides to produce tools. also that this occurs before applying sintering process, facilitate production special or specific kind parts, which will be sintered later. What not very parts used high hardness, compression resistance, surface quality and tight tolerances demanded. To meet such requirements necessary machine pieces after...

The high percentage of the refrigeration costs (17%) in operational production costs, ecological subjects, lawlegal demands related to preservation environment and human health justify recent researches about restriction towards use abundant cutting fluid machining processes. However, it is important point out that a minimal mist lubrication (mixture air oil) has been possible processes for machining, due technological development tool materials also machine-tools. objective this work test...

Value Stream Mapping (VSM) is a tool that has been used in lean manufacturing to redesign production systems several industrial sectors. As part of principles, the VSM pictorial technique identify kinds wastes existing floor and enables an easy way visualize possible alternatives eliminate them. The company considered for research traditional manufacturer gearboxes auto parts, who using locate family products. This paper proposes utilization ProModel <sup...

In the search for competitiveness machining companies are applying concepts of lean manufacturing, like fast setup, elimination losses in process. However, most users CNC machines still face a significant barrier this field: presetting tools is usually performed manually, and requires high times preparation machines. paper production caused by manual operations detached, showing results terms delays generated setup machines, also reductions utilization rates

This work accomplishes a comparative study between two distinct image compression techniques, namely the Lifting technique and Principal Components Analysis (PCA), in order to determine what of these approaches is more appropriate for cutting tool wear images analysis. were applied original producing low resolution version, while keeping important details image. The low-loss quality provided by techniques was expressed terms factor (ρ), Mean Square Error (MSE) Peak Signal-to-Noise Rate...

The relationship between suppliers and buyers has had significant changes in recent years. Among those are small medium size enterprises (SMEs) providing machining services as demanded by their clients. Usually this type of company faces difficulties to adequately manage the selling price be rendered. Larger companies on other hand have ability quickly more accurately costs related prices due utilization expensive software which often not viable for SMEs. This paper proposes a procedure...

In this work a factorial planning had been used to evaluate the CBN tool life during cut-ting SAE 8620 steel. Part U2222 of TPGW 160408 insert TX-LS TB650 and 2NU-SHMA6942 S7182BN300 classes from two manufacturers were in experiment. A 23 design was cutting process behavior reason exchange part on influences chamfer (in S T+S), advancing speeds (0.09, 0.10 0.11 mm/rpm) at speed 91.2 m/min. Model have fit by variance analysis (ANOVA) processing optimization done response surface methodology...

This paper explores the effect of grain size on machining strength in an Fe-Cr-Ni alloy (AISI 316L). Ideal growth law [1], was used to obtain activation energy level for this steel, which 185 kJ.mol -1 [2]. The initial measured (12 μm) and considering these values, both temperature time values needed achieve a final ten times larger than one, could be calculated, were 1200°C 2 hours. Ternary phase diagram analysis showed that austenite stable at temperature. Following, samples 200 mm length...

This work proposes a new methodology to optimize flexible manufacturing cells applying Simulated Annealing and Contribution Margin concepts. helps determine the number of extra products that could be sold manufactured while taking advantage this idleness. The price formation sell was based on contribution margin main concept is use cell idleness increase profits costs are already paid. Equipment workers have their fixed paid regardless whether they active or not. When not active, all...

The objective of this work is to use computer vision techniques, adopting the expe-rimental research as a methodological approach measure cutting process parameters. This will present measurement time and passive times during turning process. proposal can be easily justified because optimization com-plex task. measured results minimize costs maximize production. All measurements happen in shop floor online with evolution. involved essential allow parameters optimization.

Manufacturing cost minimization and productivity maximization are essential for the machining industries sector to survive in market. The production shop floor is a source of achieving strategic data, providing information assist cutting processes optimization better help use equipment resources efficiently. In this sense, objective work present development New Cutting Process Operational Decision Support System which following most modern computational architecture (this system being known...
