In this paper an objective fuzzy approach for fast and accurate porosity vision based inspection is presented. An automated methodology of detection of pores, which are formed in aluminum alloys during production of water-pumps for car engines with the die casting method, is described. The proposed method is based on the correlation of the core of pore candidates with twelve developed matrices resulted...
The ability of a pneumatic gantry robot to grind the edges of steel blanks was evaluated experimentally. It was found that surface quality improved after edge grinding with the applied force regulated to 30 N. Three different pneumatic circuit and force control system configurations were examined. A variance of plusmn5 N was obtained with a PLC-based open loop controller that used on/off directional...
This paper addresses an application that involves the grinding of the edges of steel blanks with a pneumatic gantry robot. It presents a PID tuning method that uses an adaptive neuro-fuzzy inference system (ANFIS) to model the relationship between the controller gains and the target output response, with the response specification set by desired percent overshoot and settling time. The ANFIS based...
