Layer Manufacturing Using Optimum Feed Control to Manufacture Functionally Graded structure

Feed rate is a very important factor of layered manufacturing as it effects build time, support structure, dimensional accuracy, surface finish and cost of the object. The changing of feeding flow affects layer manufacturing greatly. We use servomotor to control the feeding powder rate of feeding powder machine and important parameter accurately. To determine the control of feeding change, we need to understand the mode of feeding powder machine and the delay time. Furthermore, we also need to understand the and transient state mode of the beginning and ending points and synchronization of feeding powder machine to achieve the effective control of feeding powder.
