straightness motion error
相关语句
  直线运动误差
     Some scanning probe methods which include two points method, three points method and the mixed method which employs two scanning probes and one angle probe, and the errors separation methods which can separate workpiece straightness from straightness motion error of the scanning stage are used in precision machining widely. Some methods are needed to be adopted to separate the yaw error of scanning stage when it can't be ignored.
     在超精密加工中,常用来测量直线度的扫描测头法有两点法、三点法以及扫描测头加角度检测仪的混合检测方法,并且需要采用误差分离的方法将工件直线度与溜板直线运动误差分离出来,当溜板的偏摆误差不可忽略时,还需采取一定的措施将其分离出来。

A new system is proposed to measure the straightness profiles of workpiece or/and the straightness motion error of the scanning stage. The system consists of two probes and one autocollimation which can avoid zero-adjustment error for each scanning. The used error separation technology is "natural extension" which allows for reconstruction of the straightness profiles whose information is contained in the given difference measurement. This frequency domain method is adapted to measurement...

A new system is proposed to measure the straightness profiles of workpiece or/and the straightness motion error of the scanning stage. The system consists of two probes and one autocollimation which can avoid zero-adjustment error for each scanning. The used error separation technology is "natural extension" which allows for reconstruction of the straightness profiles whose information is contained in the given difference measurement. This frequency domain method is adapted to measurement of smooth or rough profiles and the large distant of probes can be used. High precision measurement of straightness is possibly by using this system and error separation technology. The high precision of reconstruction is shown by the simulation and the straightness of our ultra-precision machine tool is measured by this method.

In ultraprecision machining, multi probe methods are widely used for measuring the straightness error of the workpiece to separate the straightness motion error of the carriage. Certain algorithm is applied to reconstruct the straightness error. Various current algorithms are introduced and two kinds of novel exact algorithm for reconstructing the workpiece straightness error are proposed. These two kinds of algorithm are applicable for measuring long and short workpieces by using two point and three point methods. They are applicable for various types of surfaces including smooth, non smooth, periodic and non periodic ones and allow using large probe spacing. The results of computer simulation show the distinguishing feature of the algorithm. The proposed methods have been used to measure the straightness error on an ultraprecise granite grinding machine developed by authors.
