If it is necessary, the new location features must be machined as a result of location from the former location features. 除非有必要采用另外定位要素的其它考虑，精度可通过尽可能早地加工合适的定位要素并采用它们进行所有定位来 保证。如果必要的话，新的定位要素必须作为先前的定位要素的定位结果来加工。 2) The clamping of the workpiece. The clamping system must be such that the workpiece is held against the cutting forces, and the clamping forces must not be so great as to cause the workpiece to become distorted or damaged. 2) 工件的装夹：装夹系统必须使工件对着切削力夹持，而且装夹力又不能大得引起工件变形或损坏。 The workpiece must be supported beneath the point of clamping, to ensure that the forces are taken by the main frame of the jig or fixture, and on to the machine table and bed. When jigs and fixtures are designed, the clamping system is designed to ensure that the correct clamping force is applied, and that the clamps can be operated quickly but with safety. 工件必须在装夹点下被支撑，以保证这些力由钻模或夹具的主框架来承受并传递给机器台和床身。在设计钻模和夹 具时，要同时设计装夹系统来保证提供恰当的装夹力，并使装夹操作快速而安全
