The Straightening of Linear Guide and the Error Assessment of Straightness

After the sufficient research of straightening processing technology of precise linear straightness guide at home and abroad,in order to improve the processing precision of linear guide,a set of straightening system of precise linear guide was designed and manufactured. Brief structure diagram had been given. Based on the basic principle of straightening,LG series of precise linear guide was straightened. A series of precise measuring point data had been achieved,after the straightened linear guide was measured in CMM measurement device. By using the method of two end points and matlab software programming to deal with measured data points,the error value of linear guide straightness had been calculated easily and efficiently. The results show that the processing precision of linear guide was improved.
