Abstract
Industrial programming is a tiresome and time-consuming task that requires technical skill. Thus, new and more intuitive ways for people to interact with CNC machines are required to make programming easier. The goal is to present two methods of programming that helps users to program a machine in an intuitive way, providing a high-level of abstraction from the machine language. Therefore, this paper presents a CAD-based system to program from a 3D CAD environment, allowing users with essential CAD skills to generate programs off-line in order to facilitate and accelerate these related tasks. This is feasible due to a relatively low cost and commercially available CAD packages that enable the user to generate machining programs. The method used to get data from CAD and techniques to manipulate, simulate and convert it into CNC machine commands are presented herein. Finally, the effectiveness of the two methods is showed when the time and wastes saved in 3D programming is compared to 2D programming to perform the same task. This presented method can also contribute to improve the quality of work, increase productivity, standardize work routines, and strive for excellence in adding value. A case study is showed to evidence the benefits reached.
Highlights
Industrial programming is a task for specialists
The competitive nature of a globalized aerospace industry off-line programming can drastically reduce the machines to requires aircraft manufacturers to remain current and push stop time to maintenance, with the use of object oriented the boundaries of aircraft design in all development phases. design patterns, it is possible to minimize the time spent in Continuous progress in affordable computing power is programming (Bottazzi et Fonseca, 2005)
To be used for programming machining process in order to the method is built on the CATIA V5 platform, which is establish the contact between engineering and production widely used in the aviation industry
Summary
The competitive nature of a globalized aerospace industry off-line programming can drastically reduce the machines to requires aircraft manufacturers to remain current and push stop time to maintenance, with the use of object oriented the boundaries of aircraft design in all development phases. design patterns, it is possible to minimize the time spent in Continuous progress in affordable computing power is programming (Bottazzi et Fonseca, 2005). Direct Numerical Control) made off-line programming a realistic proposition for groups of more complex machines Based on these trends and needs, a specific methodology indirectly communicating with each other through shop floor has been proposed to enable the programming in 3D computer systems (Chan et al, 1988). These are intended environment to processing in CNC machining centre. Results are presented to certify the advantages reached when 3D programming is applied to machining of composites parts on CNC processing centre This proposed methodology can contribute to the business’ competitiveness in terms of savings as it will be presented in the study case. Continuous process chain from modeling to offline programming using native V5 data;
