Forming cylinder transmission system is the key factor in the accuracy of sprea ding powder of selective laser sintering equipment.According to spreading powder process
the overall plan of forming cylinder transmission system is determined
and the model of the transmission system is established.According to the parameters of spreading powder
the calculation of transmission system dynamic parameters and selection of stepping motor are introduced.In order to meet the accuracy requirements
finally
the analysis of the static positioning error of the drive system is carried out.
