摘要：

针对当前电缆铺设工程中电缆接头表面加工粗糙度高和轮廓一致性低的问题，提出一种新型电缆接头轮廓测量切削方法。首先，建立安装参数误差模型，借助激光位移传感器扫描接头轮廓，利用最小二乘法拟合截面轮廓，轮廓拟合误差小于0.12%，能以较高精度重构出待加工接头区域的轮廓及轴线轨迹；其次，将轮廓测量结果转换坐标得到刀具切削轨迹，根据插补算法对切削过程中的离散进刀量进行平滑处理，能有效解决控制系统带宽与切削表面粗糙度要求间存在的矛盾。通过设计的新型切削设备对提出的高压电缆接头轮廓测量及切削方法进行验证，结果表明，该方法可靠有效，可满足高压电缆接头成型工艺技术要求。

Abstract: A new measuring and cutting method is proposed aiming at the problem of high surface roughness and low profile consistency in high-voltage cable processing. Firstly, the error model of installation parameters is established袁 the joint contour is scanned by laser displacement sensor, and the cross-section contour is fitted by least square method. The contour fitting error is less than 0.12% , making it possible to reconstruct the contour and axis trajectory of joints with high precision. Then the tool feeding is obtained and the discrete feeding is smoothed by using interpolation algorithm, which can effectively solve the contradiction between control system bandwidth and cutting surface roughness. By designing this new cutting machine, the contour measuring and cutting method of high-voltage cable joints is verified, proving that this method is reliable and effective and can meet the technical requirements of high-voltage cable joint forming.
