MD380T37GMD380T45GMD380T55G加工误差数控加工误差△数加是由编程误差△编、机床误差△机、***误差△定、对刀误差△刀等误差综合形成。即：△数加=f（△编+△机+△定+△刀）其中：1、编程误差△编由逼近误差δ、圆整误差组成。逼近误差δ是在用直线段或圆弧段去逼近非圆曲线的过程中产生，如图1.43所示。圆整误差是在数据处理时，将坐标值四舍五入圆整成整数脉冲当量值而产生的误差。脉冲当量是指每个单位脉冲对应坐标轴的位移量。普通精度级的数控机床，一般脉冲当量值为0.01mm；较精密数控机床的脉冲当量值为0.005mm或0.001mm等。2、机床误差△机由数控系统误差、进给系统误差等原因产生。3、***误差△定是当工件在夹具上***、夹具在机床上***时产生的。4、对刀误差△刀是在确定刀具与工件的相对位置时产生。下列（包括但不限于）型号均为本公司在售产品，有需要的也可咨询！CACR-SR30BB1AFCACR-SR10BB1AFCACR-SR10BB1AMCACR-SR10BB1ASCACR-SR10BBCACR-SR03SZ1SS?-Y41CACR-SR03AD1KRY110CACR-SR05AA2CACR-SR15BB1BSCACR-SR15BB1CSCACR-SR15SB1ASCACR-SR15SB1BSCACR-SR30BB1AFCACR-SR30BB1AMCACR-SR30BB1ASCACR-SR30BB1BM?-Y8CACR-SR20SB1AF?-Y100CACR-SR20SB1AF?-Y118CACR-SR20SB1AF?-Y45CACR-SR20SB1BF?-Y100CACR-SR20SB1BF?-Y118CACR-SR20SB1BF?-Y45CACR-SR20SB1ASCACR-SR10SB1AF?-Y100CACR-SR10SB1AF?-Y378CACR-SR10SB1ASCACR-SR10SB1BFCACR-SR30SB1BS?-Y124CACR-SR30SB1BS?-Y19CACR-SR20BB1BMCACR-SR20BB1BSCACR-SR20SB1BF?-Y78CACR-SR20SB1BSCACR-SR44SB1AF?-Y307CACR-SR44SB1ASCACR-SR44SB1BFCACR-SR44SB1BSCACR-SR44BB1AFCACR-SR44BB1AMCACR-SR44BB1ASCACR-SR44BC1BF?-Y279CACR-SR10BB1BSCACR-SR10BB1CS?-Y37CACR-SR10BZ1SS?-Y367CACR-SR10BC1AFREPAIRCACR-SR60BE12G?-ECACR-SR60BE12M?-ECACR-SR30TZ6SS?-Y8CACR-SR44BB1BFCACR-SR44BB1BMCACR-SR44BB1BSCACR-SR44BC1CS?-Y414CACR-SR15BE12G?-ECACR-SR15BE12M?-Y8CACR-SR15BE13S?-Y44CACR-SR05AB1ERCACR-SR03AC2ER?Y95CACR-SR20SB1BFCACR-SR30BZ1SS?Y367CACR-SR15BC1KS?Y261CACRSR10BE12MCACR-SR10SZ1SF?Y221CACRSR03TZ9***Y01ACACRSR20BY1SF-CCACR-SR15SZ1SD?Y77CACR-SR15SB1AF?Y100CACRSR20BZ1SF-Y1853XYG1003CACR-SR44BB1AFCACR-SR10BB1BF?-HCACR-SR44TZ9SF?-Y03ACACR-SR44TZ9SF?Y03ACACRSR30BE12G-CCACRSR30BY1SDCACRSR15BC1KSCACRSR44BY1SF-CCACR-SR30BB1AFCACRSR05AD1KRCACR-SR20SB1AF?Y100CACR-SR20BB1AFCACR-SR03TZ6SS?-ECACR-SR05AA2AHY315CACR-SR01AA2AH-Y3)
