摘要
针对工程陶瓷圆形零件难以成形加工的问题,提出了一种金刚石线锯成形加工工程陶瓷圆弧件的新方法,以圆弧面的径向跳动为衡量圆度指标,采用单因素实验法分析了线速度、转台转速和张紧力等工艺参数对圆弧件形状精度圆度、加工效率、线弓角度、表面粗糙度、表面形貌的影响规律.试验结果得出:在本试验参数范围内,线速度越大圆弧面的圆度越好、加工效率越高、线弓角度越小、表面粗糙度越好、表面质量越好;转台转速越小圆弧面的圆度越好、加工效率越高、线弓角度越小、表面粗糙度越好、表面质量越好;张紧力越大圆弧面的圆度越好、加工效率越高、线弓角度越小、表面粗糙度越好、表面质量越好.
Abstract
Aiming at the problem that it is difficult to shape the round parts of engineering ceramics,this paper presents a new method of diamond wire saw shaping and machining engineering ceramic arc parts.Taking the radial runout of circular arc sur-face as the index of roundness,the single factor experimental method is used to analyze the influence of process parameters such as linear speed,rotary table speed and tension on the shape accuracy,roundness,machining efficiency,pantograph angle,sur-face roughness,etc The influence of surface morphology.The test results show that:in the range of the test parameters,the greater the linear speed,the better the roundness of the arc surface,the higher the processing efficiency,the smaller the angle of the pan-tograph,the better the surface roughness and surface quality;the smaller the rotating speed of the turntable,the better the round-ness and machining efficiency of the arc surface,the smaller the angle of the pantograph,the better the surface roughness and the better the surface quality;the greater the tension force,the more roundness of the arc surface is The higher the machining efficien-cy,the smaller the pantograph angle,the better the surface roughness and the better the surface quality.
