<p>The machine is particularly for machining crankshafts, having a tool slide moving in two coordinates in any angular position in relation to the eccentric crankpin of the shaft, which is centrally secured in a chuck. For complete machining of all crankpins, the shaft is stopped in any desired position, the movements calculated by computer in straight lines and on curves are initiated to machine pins and webs, and movement along the shaft can then be numerically controlled. E electronic devices are provided in the control system, by means of which, during the grooving operation, the desired value for control of the axis, which is changed over on entering the rotary circuit, is shortened by a set amount. They also shorten by a set amount the desired value for control of the axis which is changed over on the next change of quadrants. This does not affect the calculated value for interpolation.</p> |
