在金属结构件的制造中,很多零件是借氧气切割出来,因此气割出来的另件精度与余量,是在工艺过程经常碰到的问题。气割的精度也就是切割零件尺寸的精确度,它决定于很多因素,其中主要有:切割嘴移动的均匀程度、样板制造的精度、切割宽度的计算和实际的误差、切割板的位移、受切割加热的变形、切割后热处理的条件等。兹将0～3号钢以及15、30号碳素钢的氧气切割余量及公差,介绍如下:一、气割另件的余量气割余量系指图纸上切割零件增大尺寸的加
In the manufacture of metal structural parts, many parts are cut by oxygen, so gas cut out the other pieces of precision and margin, is often encountered in the process of the problem. Gas cutting accuracy is the cutting part size accuracy, which depends on many factors, including: the uniformity of the nozzle movement, the precision of the model manufacturing, the cutting width of the calculation and the actual error, the displacement of the cutting board, subject to cutting Heating deformation, heat treatment after cutting conditions. The 0 ~ 3 steel and 15,30 carbon steel oxygen cutting allowance and tolerances are described below: First, gas cutting another part of the margin Gas cutting margin refers to the drawings on the cutting part of the increase in size plus
