| At present, for the softness abrasive flow machining method to study the work, mainly focus on the theoretical analysis and the simulation research. In order to fully understand the softness abrasive flow of the actual operation and material removal of the way, and to further explore the flow of softness abrasive flow machining method, in order to adapt to the different processing conditions and processing environment needs. This article mainly as follows:1. Summarize the solid-liquid two-phase soft ground grain flow of polishing influencing the four aspects: polishing mold, polishes, polishing conditions and polishing environment; Application of the empirical formula of grinding the Princeton equation of wear concentration on the influence of the polish. Preliminary design for the softness abrasive flow machining embedded real-time measurement and control provide measured variables and provide the basis for the control variables.2. To the flow of softness abrasive flow small, cannot be in port internal use contact type sensor, the softness abrasive flow acceleration vibration signal of digital signal processing, analysis and its characteristics, through the wavelet packet acceleration vibration signal analysis on proposed based on wavelet packets characteristic signal energy for the controlled variables measurement and control method.3. From the object-oriented technology, the design of the three stages: architecture design, mechanism design, detailed design of the design for softness abrasive flow embedded real-time flow of software light framework, and, in doing so, on the basis of frame of soft ground grain flow of the design of the embedded real-time measurement and control system4. For the solid-liquid two-phase softness abrasive flow embedded real-time control system by using DSP + ARM of the implementation of the set of the high-speed DSP real-time digital signal processing power and based on ARM embedded Linux outstanding network service and its rich software functions for the solid-liquid two-phase flow of soft grits embedded real-time measurement and control system. The operation of the system software used in DSP used RMA scheduling algorithm when to actually schedulability analysis. |
