【Abstract】 The testing and the discrimination of geometry error about three-axis numerical controlled machine tools have been introduced,discussed and investigated.Geometry error of numerical controlled machine conveniently and quickly by use of double-ball-bar can be measured,and builds up the figure model of such errors based on the instruments mentioned above.Using amend NC data,made several error compensation experients.The results indicated that the several errors in production with the machine tools will be greatly reduce.更多还原
