Experience with geometric dimensioning and tolerancing is a must. 必须具备确定设备及部件的几何尺寸和公差的能力。
In the assembly process of the large workpiece, the high accuracy measurement of the geometric dimensioning and tolerancing is a key factor to guarantee the quality and performance of a complete set of the workpiece. 在大型轴孔类工件的装配过程中,工件的几何尺寸和配合公差的高精度测量,是保证整套工件质量和性能的关键因素。
