An application of multi-sensor data fusion in SLS Rapid Prototype Manufacturing

摘要：

　　There are some inevitable errors we cant avoid in the process of powder laser sintering Rapid Prototype Manufacturing Cooling System.If we dont take some measutes to eliminate the errors,they would influence the systems operation directly,but if we adopt the traditional method,testing precision cant meet the increasingly high requirement,while upgrading the hardware system will greatly enhance system cost,which cant suit the empoldering and using of most systems.In this articles,when the number of sensors is less than 10 (N<10),a new method of data processing was introduced(including cooling waters temperature,work jar temperature etc.); use the distributing chart to eliminate inevitable errors,then adopt the method of arithmetic equilibrating and batch estimating to fuse the testing data,in order to estimate the true number.
