Two-level Predictive Based Axis Control for Virtual Machine Tool
Dealing with activation of trajectory constraints within machine-tools CNC is usually performed directly by the axis controllers, leading to a compromise with axis performance. This paper presents an original strategy, including classical predictive feedback axis controllers, with an upper level real time trajectory planning module. This module realized without any structural changes in the mai...
متن کاملEfficient Web-Learning Collision Detection Tool on Five-Axis Machine
As networking has become popular, Web-learning tends to be a trend while designing a tool. Moreover, five-axis machining has been widely used in industry recently; however, it has potential axial table colliding problems. Thus this paper aims at proposing an efficient web-learning collision detection tool on five-axis machining. However, collision detection consumes heavy resource that few devi...
متن کاملMachine models and tool motions for simulating five-axis machining
This paper presents a method of determining the tool motion of a five-axis machine. The method is motivated by the imprint point method, where points on the machined surface are computed based on the tool position and tool motion. While simple linear motion can be used as a coarse approximation to this motion, this paper looks at more accurate models of tool motion based on machine kinematics t...
متن کاملDesign of a generic five-axis postprocessor based on generalized kinematics model of machine tool
This paper presents a generic five-axis postprocessor system for various five-axis machine tools. The generalized kinematics model of common five-axis machines is constructed by combining two rotational degrees of freedom on the fixture table and two rotational degrees of freedom on the spindle. The complete analytical equations for NC data are obtained through homogeneous coordinate transforma...
متن کاملKinematic Modelling of Hybrid Parallel- Serial Five-Axis Machine Tool
Compared with serial structured machine tools and robots, parallel kinematic machine tools and robots have many advantages. Many different topologies of parallel mechanisms with 3-6 DOF have been used. Considering that some limitations are indeed due to the use of parallel mechanisms, it is appealing to investigate architectures based on hybrid arrangements where serial and parallel concepts ar...
