摘　　要：为了适应目前数控雕刻的发展,针对直线插补技术提出优化,提出变单步进给为多步进给,提高插补计算速度,进而提高产品的加工效率。同时,通过数学分析的方法,针对目前使用较多逐点比较法插补算法存在的不足,提出优化,根据分析采用逐点比较法进行插补时可能会产生较大的加工误差,最大误差能达到1个脉冲当量,而优化后的半步偏差法可以使其加工误差可以减小到0. 5个脉冲当量。In order to meet the development of CNC carving, optimization of linear interpolation technology is proposed, so single step feeding will be replaced by nmhi -step feeding, which will improve the interpolation speed ,thus to improve the processing efficiency of the products. At the same time, the optimization of short- comings of the interpolation algorithm which uses more point - by - point comparison method at present is put forward through mathematical analysis. But the interpolation using point -by -point comparison method may produce larger processing error, which of the maximum error can reach one pulse equivalent . But the machi- ning error can be reduced to 0.5 pulse equivalent through the optimized half - step deviation method.
