摘要
分析了SLS直接熔融低熔点性粉末材料成型时的控温机理,将整个逐层加工过程的控温工艺分为一般层控温和关键层控温。提出了一种基于线段求差的实体截面求差的关键层判断方法,以此来判断关键层能够快速、准确、稳定的判断出关键层。实现了SLS系统的自动控温,提高了SLS系统的自动化程度。
With the analysis of temperature control mechanism in the process of Sintering low melting point powders to product parts directly,the temperature control process of SLS system has been classified as temperature control of general layers and key layers.A subtraction method of two sections based on line subtraction method has been brought forward to decide the key layers quickly, accurately and steadily hence realization of the automatic temperature control of the system and higher level of automated SLS system.
