【摘要】 研究车床对刀高度误差对车削加工精度的影响问题。提出车床对刀高度误差引起的车削加工尺寸误差模型———在分析车削加工尺寸误差形成过程的基础上,建立车削加工误差的矢量表达式;分析了存在对刀高度误差的情况下,对刀高度误差、对刀直径、车削进给量等因素引起的车削加工尺寸误差变化规律,并进一步分析对刀高度误差对切削加工形状的影响。分析表明:对刀高度误差会产生车削加工尺寸误差和形状误差,且直径尺寸误差随对刀高度误差增大而增大,且受对刀直径及进给量等因素的影响。更多还原

【Abstract】 The effect of the tool setting height error on turning processing precision is studied.A model of turning processing error caused by the tool setting height error is proposed.The vector expression of turning processing error is derived based on the analysis of the establishing process of turning dimension error.The variation law of turning processing error caused by the tool setting height deviation,the cutter diameter or the turning feed rate is analyzed.And the tool setting error on the part shape error influence is analyzed further.Analysis show s that the tool setting error w ill produce the shape error and size error, and error increases w ith the diameter size of tool setting error increases,and the cutter diameter and amount of feed and other factors.更多还原
