<DIV><FONT face=Courier>&nbsp;&nbsp; 如图1所示带孔圆盘工件，材料为45钢，分析其数控车削工艺。</FONT></DIV>
<DIV><FONT face=Courier><STRONG>1．零件图工艺分析</STRONG></FONT></DIV>
<DIV><FONT face=Courier>如图1所示工件，该零件属于典型的盘类零件，材料为45钢，可选用圆钢为毛坯，为保证在进行数控加工时工件能可靠的定位，可在数控加工前将左侧端面、Φ95㎜外圆加工，同时将Φ55㎜内孔钻Φ53㎜孔。</FONT></DIV>
<DIV><FONT face=Courier><STRONG>2．选择设备</STRONG> </FONT></DIV>
<DIV><FONT face=Courier>根据被加工零件的外形和材料等条件，选定Vturn-20型数控车床。</FONT></DIV>
<DIV><FONT face=Courier><STRONG>3．确定零件的定位基准和装夹方式</STRONG></FONT></DIV>
<DIV><FONT face=Courier>（1）定位基准&nbsp; 以已加工出的Φ95㎜外圆及左端面为工艺基准。</FONT></DIV>
<DIV><FONT face=Courier>（2）装夹方法&nbsp; 采用三爪自定心卡盘自定心夹紧。</FONT></DIV>
<DIV><FONT face=Courier><STRONG>4．制定加工方案</STRONG> </FONT></DIV>
<DIV><FONT face=Courier>根据图样要求、毛坯及前道工序加工情况，确定工艺方案及加工路线。</FONT></DIV>
