Model-driven online correction welding robot automatic programming system

In the fields of aerospace and shipbuilding, there are a large number of small-batch, flexible components to manufacture by welding. The geometric models of these components and the actual components itself often have deviations, which makes the automatic programming system based on the traditional off-line programming difficult to apply. In view of this situation, this paper designs a model-driven online correction robot automatic programming system. Through the analysis of the digitized geometric model of the component to be processed, the processing plan is planned in advance and the robot program is automatically generated. The deviation between the geometric model and the actual component is measured by the sensor, and the robot program is corrected online. Results show that the system can eliminate the influence of the deviation between the real component and the geometric model, complete the corresponding welding task effectively, and provide the technical basis for the further automation of the robot processing.

The experimental results prove that the proposed method is effective and feasible. The outcomes of this work contribute to enhancing the use of arm robot for polish free-form workpiece surfaces.

ＣＮＣ旋盤による加工での切削抵抗データに基づく加工精度向上

In a conventional automatic programming system developed for turning with a CNC lathe, NC data such as tool path, feed and rotational speed of spindle are automatically generated, when the desired shape of products, and tool and workpiece materials are specified. However, for turning of a workpiece having large length and small diameter, variation in the finished diameter along the rotational axis yields due to workpiece deflection caused by the cutting force. In the case of a shaft that requires machining using multiple tool paths, the magnitude of machining error also varies in accordance with the sequence of the turning process. To reduce the machining error in the diameter, elastic deformation of the workpiece due to cutting force, whose components are obtained through a cutting model and energy method proposed by Usui et al., is considered in the generating process of the tool path. In the analysis for chuck-center work, a finite element model of a rolling center, in which experimental results of bending test are applied, is used. From the comparison of the machining error obtained with turning test for compensated and uncompensated tool paths, it is confirmed that the proposed method is effective in reduction of machining error.
