The disclosure relates to a method and apparatus for checking and monitoring the movement of a tool carriage in response to a numerical controlled program. The path of movement of the tool carriage is recorded independently of the program control during the initial run of the carriage, in a manner capable of being subsequently sensed. The recorded path is thereafter sensed during the subsequent runs of the carriage and a signal is produced when the carriage deviates from the recorded path. The recording device includes a stationary supporting member having a surface upon which a drawing or etching may be made. The drawing or etching member is mounted to the movable carriage so as to become jointly movable therewith. The sensing member is mounted in conjunction with the drawing instrument and is interchangeable therewith during the sensing portion of the procedure.
The method of checking and monitoring the path of movement of a movable member of a numerically controlled machine tool comprising the steps of providing a system in which a track may be selectively recorded on a surface, by an instrument conjointly movable with each movement of said movable member and a system in which said recorded track may be followed by a scanner conjointly movable with the subsequent movement of said movable member, operating said machine, according to said control program, recording as a series of tracks independent of said controlled program the entire path of movement of the initial run of the said movable member according to the control program, thereafter repeating the operation of said tool in response to the control program in successive runs and causing the scanner to conjointly follow the recorded path of said tracks in each succesive run, and to sense the recorded path of said tracks during each of the subsequent runs, and producing a signal responsive to the departure of said scanner from the recorded path of said tracks.
Apparatus for checking and monitoring the path of movement of a movable member of a numerically controlled machine tool in response to a controlled program comprising a recording surface stationarily supported with respect to said movable member and movable member for an instrument for recording thereon, said instrument being mechanically connected to said conjoint movement therewith, said instrument and said recording surface cooperating on movement of said movable member to record on said recording surface a series of tracks independent of said control program corresponding to the initial path of movement of said movable member under the controlled program and scanning means arranged above said recording surface said scanning means being mechanically connected to said movable member to conjointly move therewith to serially follow the path of said tracks during subsequent runs of said movable member and means for continuously sensing the path of said serially recorded tracks producing a signal responsive the the deviation of said scanning means from said tracks indicating the departure of said movable member from its recorded initial path of movement.
Apparatus for checking and monitoring the path of movement of a movable member of a numerically controlled machine tool in response to a controlled program comprising a planar recording surface and an instrument for recording thereon, one of which being arranged for conjoint movement with said movable member, the other of which being stationarily supported, said recording surface comprising means for receiving an engraved indicia and said recording instrument comprising means for engraving thereon, said instrument being adapted to record on said recording surface a series of tracks independent of said control program corresponding to the path of movement of said movable member under the controlled program and scanning means including tactile means for sensing said engraving arranged above said recording surface for sensing the recorded tracks, said recording surface and said scanning means being relatively movable to each other conjointly with said movable member to serially follow the path of said tracks during subsequent runs thereof and means for producing a signal responsive to the deviation of said scanning means from said tracks indicating the departure of said movable member from its recorded path of movement.
