An object is to increase precision in straightness on a journal thrust surface relative to the outer peripheral surface of the journal in a crankshaft, and in the control system for controlling the movement of a cutter in axial directions by running a control program transferred from an automatic programming apparatus, the automatic programming apparatus is provided with a machining data correcting means for correcting machining data on the basis of the data for correcting the straightness gained through comparison between the results of measurement of the machining dimensions of the journal thrust surface in the workpiece on which a cutting process has been carried out in advance and the target machining dimensions for the journal thrust surface; and a program preparing means for preparing a control program on the basis of the corrected machining data after correction of the machining data using this machining data correcting means.
A method for machining a crankshaft wherein a cutting process is carried out on a workpiece using a rotary cutter on the basis of preset machining data, and thus, a thrust surface of a journal which makes a right angle with an outer peripheral surface of the journal of the workpiece is formed, comprising the steps of:
An apparatus for machining a crankshaft wherein a cutting process is carried out on a workpiece using a rotary cutter on the basis of preset machining data, and thus, a thrust surface of a journal which makes a right angle with an outer peripheral surface of the journal of the workpiece is formed, comprising:
A control apparatus for controlling an apparatus for machining a crankshaft wherein a cutting process is carried out on a workpiece using a rotary cutter on the basis of preset machining data, and thus, a thrust surface of a journal which makes a right angle with an outer peripheral surface of the journal of the workpiece is formed, characterized in that:
A program which is run in a computer apparatus for preparing a control program for controlling an apparatus for machining a crankshaft wherein a cutting process is carried out on a workpiece using a rotary cutter on the basis of preset machining data, and thus, a thrust surface of a journal which makes a right angle with an outer peripheral surface of the journal of the workpiece is formed, characterized in that the program allows said computer apparatus to carry out:
