This paper focus on a motion control card based on DSP, designed an interface communication between DSP and industrial PC. After a contrast about several methods of communication, this interface take the Dual-port RAM as the final way. This communication method regard the DRAM as the sharing storage unit, use the semaphores of the DRAM chip to prevent visiting the same address at same time on boths port and achieve the high speed communication between DSP and PC104.

Cnc Grinding Machine

The parameters of joint parts must be included in the finite element model of a whole grinding machine. The subject investigated in this paper is B2-K3000 high-precision composite flexible grinding machine. Through finite element modeling, the joint part parameters are integrated into the whole grinding machine model to establish a dynamic model and then analyze its static and dynamic characteristics. The result shows that the whole grinding machine possesses good features, but it still needs to be improved. This paper gives suggestions for its structure development and application.

Abstract. PC-based open CNC system can fully take advantage of the computer's hardware and software resources, which can use a common high-level language: Visual C++ or Visual Basic to program. User can mix and use the standardized peripherals, application software flexibly, we use the self-developed five-axis CNC machine is experimental platform, which can develop open CNC system based on PC and motion control card. Using of five-axis machine motion control design based on "PC + motion control card" on Visual C++ platform.
