Introduction

The modern stage of development of CAD-systems (Computer-Aided Design) is characterized by a significant expansion of the scope of their use. Now it is quite simple to obtain a 3D model of a part from a 2D drawing (and, vice versa), while it became possible to quickly and accurately determine a number of parameters, such as the weight of the part, its surface area, coordinates of the center of gravity and moments of inertia relative to the X, Y, Z axes. An interesting direction for improving CAD-systems is their integration with CAM-systems (Computer-Aided Manufacturing). One of the main tasks solved by CAM systems is the development of control programs for CNC machines.

Many software developers for automation of design and technological preparation of production have already equipped their systems with appropriate modules.

Firm "Ascon" has integrated into the system of three-dimensional modeling KOMPAS-3D module CNC, which allows you to receive control programs for various types of processing.

Firm "Top-Systems" has supplemented the T-FLEX CAD computer-aided design system with the T-FLEX CNC option.

1. Purpose of the study

These circumstances pose an urgent task for higher educational institutions to introduce the study of integrated CAD/CAM systems into the educational process of training design engineers. In this case, the emphasis should be placed on the practical mastery of the skills of developing control programs using a 3D-model of the manufactured part.

At the stage of choosing an automated system for obtaining control programs for further use in the educational process of the Sukhoi State Technical University of Gomel, the technique described in [9] was used.

2. The sequence of the research

Preparation for implementation in the educational process of designing using CAD/CAM systems consisted of the following stages:

1. Purchase of licensed software for 20 users, namely, T-FLEX CAD 3D and T-FLEX CNC 3D systems.

2. Installation and adaptation of the specified software to the conditions of use in the educational process of the Sukhoi State Technical University of Gomel.

3. Preparation of educational and methodological literature containing guidance on the use of a CAD / CAM system in course and diploma design. The features of this stage are described in [10].

The study of the possibility of using a CAD / CAM system in the training of design engineers was carried out by students of the specialty 1-53 01 01 "Automation of technological processes and production (by directions)" when performing a course project in the discipline "Automated systems for technological preparation of production" and when completing a diploma project.

The development of the control program was carried out in the T-Flex CAD computer-aided design system using the T-FLEX: CNC option.

To obtain the control program, the following steps were performed:

1. Using the "Tool Editor" command, a cutting tool with the required parameters was created and saved in a file with the ".too" extension (Fig. 1);

2. On the toolbar, the command "Drilling 5D" was selected, and in it the name of the operation, the tool, the surface relative to which the machining is performed and the drilling parameters (depth, speed, feed, etc.). The results of this processing are shown in Fig. 2-4;

Conclusion

The introduction of an integrated design system into the educational process has shown not only the possibility of obtaining a control program for a CNC machine tool, but also the practical implementation of this possibility by students on the basis of licensed software. The results, in the form of control programs obtained in the course of diploma design using integrated CAD/CAM systems, were highly appreciated by the members of the State Examination Commission

ВНЕДРЕНИЕ ИНТЕГРИРОВАННЫХ СИСТЕМ ПРОЕКТИРОВАНИЯ

В УЧЕБНЫЙ ПРОЦЕСС

Учреждение образования «Гомельский государственный технический университет имени П. О. Сухого»,

г. Гомель, Республика Беларусь

Современный этап развития CAD-систем (Computer-Aided Design) характеризуется значительным расширением сфер их использования. Интересным направлением совершенствования CAD-систем является их интеграция с CAM-системами (Computer-Aided Manufacturing). Одной и главных задач, решаемых CAM-системами, является разработка управляющих программ для станков с ЧПУ.

Многие разработчики программного обеспечения для автоматизации конструкторско-технологической подготовки производства уже оснастили свои системы соответствующими модулями.

Указанные обстоятельства ставят перед высшими учебными заведениями актуальную задачу ввести изучение интегрированных CAD/CAM-систем в учебный процесс подготовки инженеров-проектировщиков. Упор при этом нужно сделать на практическое овладение навыками разработки управляющих программ с использованием 3D-модели изготавливаемой детали.

Описаны этапы подготовки к внедрению системы, начиная с анализа рынка необходимых программных продуктов и заканчивая адаптацией лицензированной системы к условиям использования в учебном процессе университета. Дается ссылка на описание методики, используемой при оценке автоматизированных систем на стадии, предшествующей проведению тендера на их закупку. Подчеркнуто, что исследование возможности использования CAD/ CAM-системы при подготовке инженеров-проектировщиков было проведено студентами при выполнении курсового и диплоного проектов по дисциплине «Автоматизированные системы технологической подготовки производства». Приводится методика проектирования управляющих программ, используемая студентами, и дается оценка полученных результатов.

Ключевые слова: подготовка инженеров-проектировщиков, управляющая программа, CAD/CAM-система, программно-управляемое оборудование.
