镗削加工的精度是镗孔的形状精度和尺寸精度,孔的平直度和平行度、孔的位置精度的综合精度,本文分析镗削加工中影响加工精度的几个主要问题。一、弹性对加工精度的影响对于机械加工来说一般必须在加工过程中保证加工精度。镗削加工,由于镗杆或者伸出过长的主轴刚性低,因而与其它切削加工相比,弹性的影响较大。下面根据F凯尼格斯伯杰、J·特勒斯蒂的研究来说明其关系。切削力一般可用下式计算:
The accuracy of boring is boring shape accuracy and dimensional accuracy, hole straightness and parallelism, the accuracy of the position of the hole accuracy, the paper analyzes the boring process affecting the machining accuracy of several major issues. First, the impact of flexibility on the machining accuracy For machining in general must ensure that the processing accuracy in the processing. Boring, due to the boring bar or extended long spindle rigid low, so compared with other cutting, the greater the impact of elasticity. The following is based on the study of F Kenneth Berger and J. Telisty to illustrate the relationship. Cutting force can generally be calculated using the following formula:
