ABSTRACT:
An apparatus for controlling the application of feed motion to a working member in a machine such as a honing machine including a working member mounted on a support structure or mandrel and movable thereon into engagement with the work surface, mechanism movable to advance the working member under pressure into engagement with the work surface, and other mechanism to predeterminately control and limit the feed motion, independent of pressure, the other mechanism comprising a dash pot assembly having relatively movable portions one of which is pivotally attached to the machine and the other of which is axially movable relative thereto, a spring normally biasing the portions of the dash pot assembly together into a predetermined inoperative condition, cooperatively engageable cam and cam follower members including mounting structure therefor operatively engageable with the other portion of the dash pot assembly, a link member operatively connecting the cam follower member to the feed up mechanism on the machine that is used to movably advance the working member into engagement with the work surface, an operator actuatable member operatively connected to the cam and to the other portion of the dash pot assembly and movable when actuated to preset the cam and the dash pot assembly to predetermined positions at the beginning of each machine operation to control the feed of the working member against the work surface, and an adjustment mechanism operable to establish the distance over which the apparatus controls and restrains the application of feed to the working member, the dash pot assembly including an adjustment member operable to establish fluid flow between the relatively movable portions thereof.
