Bending machine is the most widely used bending apparatus. With the development of machinery industry and the improvement of product quality, a visualization automatic programming system of bending machine based on machine vision was developed in order to meet the need of high-speed, automated, simplified and personalized production. Based on a CNC sheet metal bending machine with three degrees of freedom, the structure of the system takes industrial computer, image acquisition card and motion control card method, and the control software is developed by Visual Studio 2010, which has advantages of fast processing speed, high accuracy and low price. The system is based on the modular design method and is mainly composed by the machine vision measurement module, bending simulation module, motion control module, human-computer interaction module, etc. In this paper, the bending machine system will be introduced and finally some simulation test of the modules will be presented.

In view of the current situation of line contact efficiency of NC machining without automatic programing system, the automatic programming system for NC machining based on line contact processing is developed. According to the characteristics of line contact processing, the key technologies in the automatic programming system of this paper is studied. After surface modeling, the data of DXF files generated by CAD systems can be read. And the surface processing information is obtained by these data sorted. Through the design of machining process and the sorting of tool path, the tool path of line contact processing is got. Then the research of soft cut of ruled surface is completed, and the graphical automatic programming is realized.

The motion relationship model of all axes involved in CNC hobbing machines is established. A single pitch adjustment method based on motion coupling relationship in gear hobbing is proposed. With position adjustment of only 0 to 1 pitch, the same motion coupling relationship during the whole machining process can be guaranteed. Though automatic programming system based on SINUMERIK 840D, the coupled motion control and adjustment in CNC hobbing process is realized. And practical application in CNC hobbing machines shows that this method can reduced adjustment time effectively during process, improving processing efficiency.

This paper provides the details of continuous cutting technology to architectural model made by EPS. To solve the interference problem between outline surface and hot cutting-wire in the cutting process, STL model projection profile method is used. Slicing algorithm based on grouping matrix is proposed to cutting the outline model continuously. Local topological relations in each group are established to improve the efficiency of slicing cutting. In order to apply this algorithm to the actual process better, automatic programming system with Visual C + + 6.0 based on STL model is developed, which used the 5-DOF CNC thermal device to cut the model. The experiment shows that this technology can cut the outline architectural model efficiently and accurately.

The grinding wheel-profile is mostly formed by adjusting the angle of cylindrical profile model when regrinding gear hob with the large helix flute. Repeat trial cutting is needed with this method, which results in low efficiency. In order to improve the efficiency of processing, a mathematical model of grinding wheel profile was establish in according to forming principle of the rake face of gear hob and accurately calculate grinding wheel-profile. A automatic programming system of calculating grinding wheel-profile and automatically generate NC code is developed with the developing tool of VC++.

AN automatic programming system SPACE WITH HIGHLY VISUALIZED AND ABSTRACT PROGRAM SPECIFICATION

IEICE TRANSACTIONS ON INFORMATION AND systemS 1995年第4期E78D卷 403-419页

In this paper, it is stated that visualization and abstraction of program specifications can be highly integrated on the basis of decision tables and condition expressions. In order to demonstrate this idea, we developed an automatic programming system called SPACE: SPecification Acquisition and Compiling Engine. SPACE is designed to ease the production of business data processing program. SPACE has functions both to support the creation of visual program specifications and to generate COBOL programs according to the input program specifications. To visualize program specification, SPACE design windows are comprised of two diagrams and four tables in a formal similar to the conventional detailed design sheets. To represent module functions, in particular, a visualized computation model called a decision table is used. All the possible execution states of a module are represented by combining the state function called condition expressions. The condition expressions represent the typical file processing patterns in very familiar form to actual business application designer. They do not simply give function values;each of them carries out implicit attached procedures according to the characteristic I/O control logic for business data processing. Hence users can describe program specifications concisely by designating merely the condition expression instead of the detailed I/O control logic. This paper uses sample descriptions of stock control problems to explain how visualization of computation and abstraction of algorithm can be integrated and formalized on a basis of a decision table and a condition expression. Also the paper describes how to generate programs from visual specifications.

A dual-arm robotic simulation system is described. It can simulate dual-arm kinematics and dynamics, multi-manipulator cooperative control systems, trajectory planning, and typical tasks of robots. The package provides a dual-arm robotic language and a 3-D graphic display. To study the multi-manipulator cooperative control method more efficiently, it also provides a general user interface and an automatic programming system. The overall structure and a general simulation algorithm are outlined.

GRAPHICAL INTERACTIONS WITH AN automatic programming system

引用

IEEE TRANSACTIONS ON systemS MAN AND CYBERNETICS 1988年第4期18卷 575-591页

作者： SCHAFER, AL MITRE Corporation Bedford MA USA

ISFI, an automatic programming system, accepts a nonprocedural specification of the desired behavior of a computer program. This specification is augmented by ISFI until computations to accomplish this behavior can be derived, and then compilable code is generated. ISFI\'s graphical interface (IGI) permits input, modification, and exploration of the specification, including the part added by ISFI in the process of solving the programming problem. This interface supports the special requirements of an automatic programming system, the needs of programmers debugging any large complex computer system, the normal requirements of an interactive user interface, and the potential graphics to aid the visual thinking process of humans. The ways in which IGI addresses these issues are described and some enhancements are suggested.

The recent advanced CNC, with large built-in memory, has made possible the "memory operation" capable of tapeless operation, as in conventional DNCs. Work loading and unloading has been one bottleneck in labour saving. But an advanced low-cost robot and controlling it by a CNC have automated not only machining but also machine shops. This paper introduces CNCs, servo motors, robots, and recent technical developments in CNC machine tools, and hints at a future of automation in machine factory.
