Research On Accounting And Application Of Environmental Costs

Intense current electron beam on the gear components and mold surface processing, high-quality parts available surface. But how to control movement to achieve the table-the entire surface of the processing is an important subject. Based on the research on the subject, mainly in the following research results.Design of the electron beam material surface finish processing the table and realized the table in a vacuum indoor two-dimensional movement. SCM adopted a pulse, through the stepper motor drives the distribution of current, the stepper motor in accordance with the speed of rotation set. PC-control software through serial communication interface with the microcontroller communication, set the number of pulses and pulse cycle. Table by the open-loop control control, table motion error may exist in the pros and cons to the space agency, the stepper motor step angle error, and so on. Through the electron beam processing path optimization, the development of the use of the control of the mobile workstation visualization software so that the table can be set according to the processing tracking movement. Precision workstations launched a campaign of testing and compensation for the error, the error has controlled automatic compensation to the accuracy of processing the request of the table successfully applied electron beam processing system has laid an important foundation.
