Thermal Error Modelling for Real-Time Error Compensation
A modelling strategy for the prediction of both the scalar and the position-dependent thermal error components is presented. Two types of empirical modelling method based on the multiple regression analysis (MRA) and the artificial neural network (ANN) have been proposed for the reaLtime prediction of thermal errors with multiple temperature measurements. Both approaches have a systematic and c...
متن کاملSensor-based Real-time Error Compensation
Machining accuracy can be greatly increased through the use of highresolution position sensors, calibration of machine tool or robot components, and other measures which serve to improve the machine’s positional response to part programs. Unfortunately, much of the inaccuracy in finished parts is due to dynamically varying quantities, such as tool wear, chatter, or thermal expansion; random err...
متن کاملThe real-time error compensation technique for CNC machining systems
One of the important trends in precision machining is the development of real-time error compensation technique. This paper presents the research work under the authors and their team in this area. The technique has been applied to more than 10 different kinds of machines including: turning centers and machining centers; small, medium and large machines; new products and retrofitted machines. T...
متن کاملReal-time Texture Error Detection
This paper advocates an improved solution for real-time error detection of texture errors that occurs in the production process in textile industry. The research is focused on the mono-color products with 3D texture model (Jaquard fabrics). This is a more difficult task than, for example, 2D multicolor textures.
متن کاملError Compensation for Radome Measurements
Geometries for measuring radome characteristics can usually be split into two categories. The first category always has the antenna inside the radome pointing along the range axis. The second category has the antenna maintaining a fixed relationship with respect to the radome during each scan of data. A facility can generally be designed to minimize measurement errors in one of the two geometri...
