本文以机器人去除高压铜触头表面残留物为背景,采用响应面试验设计方法(RSM)对机器人去毛刺工作参数进行优化。采用BBD(Box-Behnken)方法设计了基于切削用量三要素的实验方案并进行三因素三水平实验,选取压强P,进给速度V,和侧吃刀量作为三个输入因素,切削切向力和棱边表面粗糙度分别作为响应值,经模型方差分析,响应面分析,以及切削切向力优化,获得最优工艺实验参数,并进行了最优工艺参数实验。结果表明,机器人去毛刺最优工作参数为转子压强为0.27Mpa,进给速度为30mm/s,侧吃刀量为0.06mm,在此最优条件下,可使得机器人在去毛刺时的表面粗糙度最小,切削力适中,可以满足优化目标。

Abstract
In this paper, the deburring parameters of the robot were optimized by response surface
design method (RSM) based on the background that the robot was used to remove residues on
the surface of high-voltage copper contacts.Using BBD (Box - Behnken) method to design the
experiment scheme based on the three elements of cutting dosage and three factors and three
levels experiment, the selection of the pressure P, feed speed V, and side turning as three input
factors, cutting tangential force and surface roughness of edge as response value, respectively,
by the analysis of variance model, response surface analysis, optimization and cutting
tangential force, to obtain the optimal process the experimental parameters, the optimal
process parameters is made and experiments has been done.The results show that the optimal
working parameters of the robot for deburring are rotor pressure of 0.27mpa, feeding speed of
30mm/s and side cutting amount of 0.06mm. Under this optimal condition, the surface
roughness of the robot during deburring can be minimized, and the cutting force is moderate,
which can meet the optimization objective.
