由浙江大学电机系工业电子技术教研组研制成功的SKW型正负法精密数控绘图机于去年十二月通过鉴定。 SKW型正负法精密数控绘图机是一台中型的绘图设备,绘图机的关键设备控制柜是由以浙大应用数学教研室的科研成果——“正负法绘图”产生基本曲线的方案为数学模型,并加上硬件化了的专用电子计算机而构成。该机能根据给定的数学方程式直接产生直线(包括斜线)、各种二次曲线(圆、椭圆、抛物线、双曲线)、三次多项式曲线
By the Department of Electrical Engineering, Zhejiang University, Department of Industrial Electronics Technology Research Institute successfully developed SKW positive and negative precision CNC plotter passed in December last year identified. SKW positive and negative precision CNC plotter is a medium-sized drawing equipment, plotter key equipment control cabinet is by the Zhejiang University Department of Applied Mathematics research achievements - “positive and negative method of drawing” to generate the basic curve of the program for the mathematical model , And with the hardware of a dedicated electronic computer and composition. The machine can directly generate a straight line (including slash), various quadratic curves (circles, ellipses, parabolas, hyperbolic curves), cubic polynomial curves according to a given mathematical equation
