Abstract.A new vibration device of process electrode has been provided in the paper, which achieves the aim of developing process state and improving process speed. Set out from improving system process efficiency and process quality, it analyses the characteristics of EDM and make sure appropriate parameter and control system configuration. Combined the characteristics of fuzzy controller and artificial nerve net, it designs portable EDM nerve fuzzy control system, which uses in adjusting the parameter of servo control system and revises some disadvantages of faulty rule to improve quick respond capacity of control system. Applying fuzzy theory and simulation means, it analyses the portable EDM servo control system and proves the stability of the EDM control system in theory. Through typical experiments, the process efficiency of device has been testified.

We compared the foundry PA6G samples in several dry and humid but different storage environments by processing them under the same cutting conditions such as progress rate (100, 120, 140, and 160 mm/min), cutting rate (90, 110, and 130 m/min), and cutting depth (1, 1.5, 2, 2.5, and 3 mm), in terms of formation of average surface roughness values. An improvement of 10.4% in average surface roughness was observed in the measurements performed after the milling process on the humid material and then the process was carried out under a dry condition. Degradation of about 14% in the average surface roughness was observed. The measurement was carried out after the samples were used in milling measurement which was performed on the dry PA6G material that was kept in a humid environment. An improvement of 6.4% in average surface roughness was observed. The measurements were performed after CNC machines process was applied on humid and dried PA6G material. This difference between milling and turning procedures is caused by the workpiece losing its humidity in the turning machine due to the turning effect. It was noted that the processes performed on the CNC turning stand were less affected by the humidity factor.

“…Por outro lado, a rugosidade é considerada predominantemente como a característica mais importante de superfícies de engenharia devido a sua influência no desempenho do componente usinado. Comparada com a usinagem convencional, porém, a qualidade de micropeças é muito mais difícil de ser controlada e a qualidade de microcomponentes tornou-se um aspecto pertinente de microusinagem (Wang et al, 2005;Zaman et al, 2006).…”

RESUMONa última década, diversas pesquisas demonstraram como o software de elementos finitos pode ser usado para prever a formação do cavaco, as forças de corte, a temperatura, o desgaste da ferramenta, as tensões residuais na peça e outros parâmetros importantes na usinagem. Este artigo apresenta simulação usando FEM (Finite Element Method) com validação experimental no microtorneamento ortogonal do aço AISI 4140. Simulações de usinagem utilizando o software de FEM AdvantEdge® foram aplicadas para prever as forças de corte e de avanço, tensões de von Mises, tensão máxima de corte, deformação plástica, taxa de deformação e a distribuição de temperatura de corte. O trabalho visa avaliar a evolução das variáveis citadas em função do avanço utilizando ferramentas de metal duro sem revestimento. O corte ortogonal foi validado comparando as forças de corte obtidas experimentalmente com os resultados simulados. Também foi realizada uma previsão da temperatura de corte, deformação plástica e taxa de deformação plástica durante a usinagem de aço AISI 4140. A combinação da técnica de elementos finitos com medições reais de teste de corte permite melhorar e aperfeiçoar as condições de usinagem. Os resultados experimentais e simulados mostraram valores próximos no que respeita a força de corte. Palavras-chave: Aço AISI 4140; FEM; Simulação de usinagem; Temperatura de corte; Microusinagem. ABSTRACTIn the last decade, various researches has shown how the finite element software can be used to predict the chip formation, cutting forces, temperature, tool wear, residual stresses in workpiece and other important parameters in machining. This article presents simulation using FEM (Finite Element Method) with experimental validation in orthogonal microturning of AISI 4140 steel. Machining simulation using FEM AdvantEdge® were applied to predict the cutting and thrust forces, von Mises stress, maximum cutting stress, plastic deformation, deformation rate and cutting temperature distribution. The work aims to evaluate the evolution of these variables as a function of feed rate using uncoated carbide tools. The orthogonal cutting was validated by comparing the cutting forces obtained experimentally with simulated results. Predictions of cutting temperature, plastic deformation and deformation rate during the machining of AISI 4140 steel were also obtained. The combination of finite element technique with actual measurements of cutting test allows to improve and to optimize the machining conditions. Experimental and simulated results showed close values as regards the cutting force.
