Three-axis processing of laser inner engraving machine control system can carry on multi-axis linkage control. Furthermore, it ensures multi-axis of high feeding speed and trajectory control of high precision. This article introduces the design of laser inner engraving machine movement control system. The core is a digital integrator of linear interpolation algorithm to generate the desired trajectory and control XYZ axis linkage. Wide speed range of servo motor and position detector resolution is adequate to constitute a half-closed loop drive. With integral separation algorithm being introduced in the controller, the speed of numerical control system, track speed and positioning accuracy are guaranteed in order to achieve optimal specification for dynamic and static characteristics of the whole system.

This paper will give a solution of measurement and control system based on FPGA embedded system for the Plastic Material Dynamic High-speed Tensile Machine (PMDHTM) with 1-100s-1strain rate range. Using sub-modules design of Nios II soft-wore and SOPC to build measurement and control system. The state machine algorithm and servo drive device are applied to accomplish precise state control of the linear shaft motor. Collecting the stress data online and non-contacting strain measurement is adopted. The test result can well meet the linear motor control response demand below the 5Hz frequency. Compared with other control based on SCM, DSP and so on, it supplies an innovation way for the PMDHTM control.

In order to satisfy the magnetic rheological polishing process, we established a measurement and control system based on SIEMENS 840D numerical control system. The structure of the system are introduced in detail, i.e. the four component modules, the seven component units establishing the hardware platform, and the three component parts establishing the electric control system design. The measurement and control system presented in this paper provides guidance for the relevant products.

According to the all-pervading theory, the best strategy for multiaxis compliant control system is the famous hybrid movement/force control. Until now, the typical way to get it inclines to integrate force control with movement control into one numerical control (NC) interpolator. The more axes being taken for the interpolator, the lower calculating and computerizing speed and the greater errors are. Furthermore, the errors of movement control, including the position errors and pose errors, would inevitably disturb the processing of force control for their coupling relationship. In this paper, the orthogonal movement/force servo strategy is brought forward based on the orthogonality relation of force control and movement control. Combining with the processing of aspheric surfaces polishing, the paper develops a new three-axis computer numerical control (CNC) compliant polishing method and system by the hybrid orthogonal movement/force servomechanism, in which the force controlling and movement controlling are taken in its orthogonal complement space, respectively. Experiments show that this new polishing system is of great robustness for the change of slope and curvature of the aspheric surfaces and it can polish aspheric surfaces to get ultrasmooth surfaces at nanoscale.

3-axes motion is broadly used in industry numerical control machine. Many motion controller we use are usually limited by the number of interface it consist. But the kind of motion controller based on CAN (Controller Area Network ) can solve this problem properly. We can add a controller of one axe conveniently. I use a Advantech CAN motion controller to build the motion control system.

The digital integrator algorithm was used to design a fine interpolation open-loop numerical control system with the FPGA as a microprocessor to achieve a three-axis linkage. On the basis of analyzing the digital integrator interpolation principle, this paper is prepared to provide an overall program design, with the simulation being completed by VHDL language programming. As evidenced by the simulation results, the FPGA-based interpolator on digital integration can easily achieve the more complex movement, providing an effective way for the machining interpolation.

The remanufacturing for the traditional idle relief grinding machine is introduced in this paper to overcome its shortcomings, such as low precision, low automation degree and poor flexibility. The drive system of the traditional relief grinding machine was renovated with ball-screws and servo-drive system Sinamics S120, the original control system was replaced by numerical control system Sinumerik 828D. After remanufacturing, the mechanical structure of the traditional relief grinding machine is simplified and the machining accuracy meets the requirements. The automation degree and the flexibility of the machine are enhanced, and the labor intensity of the workers is reduced.
