Abstract:
CNC machine tools are increasingly often used in industry, and the development of the methods of their programming is also proceeding. Modern multipurpose multi-axial machine tools are programmed using special CAD/CAM software programs. Universal special programs for controlling CNC machine tools can, however, be generated in programs written in high-level languages. An example can be the machining of gears on universal CNC machine tools using versatile machining tools.

Abstract:
AbstractThis paper presents a convenient and an easy to use manufacturing method for parts with axisymmetric geometry on CNC milling machines. The desired form of the cavities is achieved by selecting as generatrix curve any plane curve, implicitly or parametrically defined, which fulfills specific imposed by the user criteria (functional, aesthetic or other). Each machining pass is modelled as a path composed of generatrix curve segments and semicircular arcs. The surface quality is controlled by keeping the distance between successive scallops within a programmed value. Tool motion along the desired paths is generated by G-code algorithms that exploit the parametric programming technique, a powerful CNC programming tool. The effectiveness of the proposed method is verified by simulation tests for three representative curves.

Abstract:
AbstractHole drilling is the most common machining operation performed on computer numerical control (CNC) machine tools or machining workshops. Drilling appears to be a relatively simple process however; when it involves drilling deep holes, it becomes one of the most complicated metal cutting processes. Although modern machine tool controllers are equipped with special drilling canned cycles, these cycles have significant constraints mainly due to their limited framework of application. The present work proposes a general G-code algorithm intended to accommodate effective deep hole drilling. The algorithm is characterized by flexibility in the pecking strategy and adaptability to the needs of each individual drilling case. The development of the proposed algorithm is based on parametric programming which is a powerful CNC programming technique.

Abstract:
Computer numerical control (CNC) machine has greater utility in the modern advanced industrial field. This paper deals with the parametric effects such as spindle speed (1500-2100 rpm) (N) (X1), depth of cut (DOC) (0.15-0.55 mm) (X2) and feed rate (f) (30-50 mm/min) (X3) on machining characteristics like tool wear rate (TWR) and surface roughness (Ra) during fabrication of IS-617 Aluminum miniature component by advanced CNC lathe using Tungsten-carbide tool. The article analyzes the second-order mathematical model development with co-relation of co-efficient of regression (COR) and analysis of variances (ANOVA) using desirability function analysis during the production of the miniature segment. The paper also consists of multi-criteria optimization for achieving the optimal parametric combination for minimum surface roughness and tool wear rate for this manufacturing operation. The paper also shows the fabricated micro-product of Aluminum at the optimal parametric conditions using CNC programming. It is found that spindle speed has a greater effect on the tool wear rate and depth of cut has dominating effects on surface roughness of job specimen. Desirability parametric combination for minimized surface roughness as well as tool wear rate has been found 1523 rpm/0.15mm/30mmmin-1.

Abstract:
The use of CAM system to create tool s trajectories in outline of simple geometry depends directly of knowledge and ability from user in how to maintain the information and make use of available riches from these systems. The parametric program requires a solid knowledge in CN programming and the results referring to CNC machine s performance are directly connect to the way of programming to obtain these results. The aim of this study was to develop a practice s analysis between parametric program and a CAM system in a specific CNC machine, based on acting time and speed of tool s progress to each programming method. The counting of time was accomplished through CNC controller, which shows the execution time of each program from its beginning until receiving or reading the stop command. The comparison between these programming methods created results that depend of the programming way, but who receive interference of controller s technologies recourses to put in action the CNC axis machine. With these testing, it was possible to demonstrate, by means of parametric programs, an increase of 65% in performance, when compared to other programming methods.<br>A utilização de sistemas CAM para a geração de trajetórias de ferramenta em contornos de geometria simples depende diretamente do conhecimento e da capacidade do usuário na alimentação das informações e na utilização dos recursos disponíveis desses sistemas. A programação paramétrica exige uma base sólida no conhecimento da programação CN e os resultados que se referem ao desempenho da máquina CNC estão diretamente ligados à forma de programação para a obtenção desses resultados. O objetivo deste estudo foi desenvolver uma análise de desempenho entre a programação paramétrica e um sistema CAM em uma máquina CNC específica, com base nos tempos de execução e velocidade de avanço da ferramenta para cada método de programação. A contagem de tempo foi realizada através do controlador CNC, que indica o tempo de execução de cada programa a partir do seu início até o recebimento ou leitura do comando de parada. A comparação entre esses métodos de programação gerou resultados que dependem diretamente da forma de programação, mas que recebem interferência dos recursos tecnológicos do controlador para o acionamento dos eixos da máquina CNC. Com essas experimentações, foi possível demonstrar, através de programas paramétricos, um aumento no desempenho em até 65% quando comparado a outros métodos de programação.

Abstract:
A reconfigurable gear machining numerical control system (NC/CNC) architecture is proposed in this paper. The CNC platform can be quickly applied to gear hobbing, shaping, milling and grinding machine, through simple reconfiguring or parameter setting. Parametric automatic programming technology, high speed and high precision electronic gearbox, process database technology are studied. Based on the analysis of the gear machining process, the mathematic model on automatic programming of gear machining is established. Based on the Windows CE operating system, the CNC gear machining automatic programming system is developed on the ARM+DSP hardware platform, including the design of human-machine interface, automatic programming algorithm and other modules. With the support of the automatic programming and process database modules, NC codes can be generated automatically just by inputting gear parameters, tool parameters and process parameters, then, the interpolation data structure can be generated by interpreter module. A new kind of software electronic gearbox (EGB) and its implementation methods are also researched in the embedded CNC. Data flow among the modules is analyzed. Finally, experiments are conducted, and the tracking error and contour error are analyzed. The results show that the proposed gear machining CNC architecture is effective.
