Since the advent of the robots, they are widely applied in many areas of industry all over the world. With the advancement of the robot, many new research theories and technologies are developed on it. The single one impacted much more quickly and significantly is the application of computer offline simulation technology nowadays. Based on some relevant theories of robot, this paper suggests a new approach toward the offline research for the industrial robot. This method combines three advanced softwares with each playing an important role and making the best of their advantages respectively. It built a 3-D model for a 6-DOF welding robot in SolidWorks, worked out the simulation results of expected processing trajectory planning for the six links in MATLAB, then verified the trajectory simulation results and simulated the motion further in ADAMS. The kinematics simulation produced the processing motion course and relevant kinematics curves. The results indicate that the manipulator could implement the welding process according to the expected trajectory successfully and the total welding motion process and the poses of the robot just in time could be observed intuitively and dynamically. Also, this simulation lays a foundation for other virtual offline kinematics researches on robot by using relevant computer softwares without the actual robot.
Virtual Manufacturing is the use of a desktop virtual reality system for the computer-aided design of components and processes for manufacture. Virtual reality is a computer technology that enables users to view or 'immerse' themselves in an alternate world. Immersion and man-machine interaction is the core of VR technology. VR technology has obvious applications in education and training where potentially dangerous tasks such as flying or surgery are carried out and also has been used for many different applications in a variety of industries. This work provided some insight into reconstructing of virtual machining center by using Virtools platform and realized the machining center navigation and man-machine interactive operation. In this virtual environment, users can operate the machining center and complete a product machining process. Through this virtual platform, users can obtain knowledge about structure of machining center and get familiar with the complex operation of machining center before they have opportunity of manipulating the real machining tool, which is desirable for practical operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
