It is very important to measure linear cycle plane positioning accuracy of NC lathe as it affects all other parts of machines machined by them in industries. If the plane positioning accuracy of NC lathe is bad, the dimension accuracy and the change-ability of works will be bad in the assembly of machine parts. In this paper, computer software systems are organized to measure linear cycle plane positioning displacements of ATC(Automatic tool changer) on zx plane of NC lathe using two linear scales and the time pulses comming out from computer in order to get data at constant time intervals from the linear scales. And each sets of error data obtained from the test is discripted to plots and the results of linear cycle plane positioning errors are expressed as numerics by computer treatment.
