Abstract
An apparatus for automatically controlling the operations of a machine tool such as a honing machine or the like, which apparatus sets in motion apparatus which controls and maintains the operating cycle of the machine automatically and without requiring further operator attention once the machine cycle is started and until the operation has been completed whereupon the machine operation is automatically terminated. The subject apparatus includes control features which relieve the operator from maintaining pressure on a foot pedal or other machine operator member, it relieves the operator from making a decision as to when a machining or honing operation has been completed, it enables an operator to make more uniformly consistent parts, it minimizes the operator attention required to repetitively hone or otherwise produce similar parts, and the subject control apparatus may include features by which the rate at which the work engaging members are brought into operative engagement with the work is predeterminately controlled depending upon the condition of the work including the smoothness of the work surface and the characteristics of the work members. The present control apparatus is especially adaptable for use with automatic shut-off apparatus such as that disclosed in Sunnen U.S. Pat. No. 3,868,007, issued Feb. 25, 1975.
