线切割机床的误差是指线切割结束的时候切割完成拿到的工件与期望值的差距。这个差距可能来自机床精度,可能来自材料的变形,可能来自计算的失误,也可能来自机床计算控制的错误,其中包括:<br /> <div style="text-align:center;"> <img style="max-width:100%;" src="/uploads/image/20191225/20191225093654_1699.jpg" alt="" width="450" height="480" title="" align="" /> </div>  1、计算失误:这是人的原因,是可以验算,可以证明的,也是可以早期发现的。中间计算过早的四舍五入,多次重复使用一个位数不够的无理数(如多齿形时),十进角度制与度分秒制混淆等?br /> 2、机床控制错误:发生的频次是极少的,因为现今的机床控制系统是久经考验,技术成熟的。人为制造的错误它会拒绝接受,它接受下来也可以在加工前校验或回零检查。因多次旋转平移所累计的误差回零检查也可以发现?br /> 3、材料变形:只要有良好的操作习惯,计算完了要预演,输入完了要校验,开工之前要校零,手轮刻度要核对。自己没算错,机床也没走错都应有充足把握,所剩就是变形了,只是变形的原因和克服的办法要仔细琢磨了?br /> 4、线切割机床的精度:这通常是指机械精度,是实际值与理论值的那个差值。产生这个差值的最直接原因是回差和直线度、垂直度。这个差值的范围应该?.005~0.02mm以内,这个数值是可以测量的,可以调整的,就现今机床结构来说,要使这个误差值控制在0.02以下是很容易的,而要?.005以下又是很困难的?br /></div> <div class="newArtiNext"><div>上一?<a
