    摘要: A touch pad machine control system uses a touch pad having an overlay to define control strip surface areas which perform different functions. The contact of an operator's finger along one of the defined control strips selects a desired function and produces the desired machine motion from the rate, distance or duration of finger contact according to the desired function. The result is equivalent control motion without the need for moving parts.

    摘要: A dimension comparator for machine tools is disclosed wherein a first comparator compares a theoretical numerical dimension with an actual dimension as determined by a position measurer. After it is determined that the actual dimension is greater or less than the theoretical dimension, a second comparator compares the actual dimension to a numerical value representing the theoretical dimension plus or minus the numerical value of an aiming interval. This representative numerical value is determined by an adder controlled by the output of the first comparator. In an alternative embodiment, means are provided for controlling the adder to add predetermined increments to the theoretical dimension for comparison in the second comparator.

    摘要: In order to permit manual operation under a condition where the axial direction of a tool and the direction of a hole to be machined in a workpiece are held in agreement, the tool of a radius .gamma. is rotated by .theta. in the vertical rotational direction and by .rho. in the horizontal rotational direction in a orthogonal coordinate system and in a spherical coordinate system the origins of which coincide with the center of rotation of the tool. Upon doing so, in the orthogonal coordinates, the position of the front end of the tool becomes X.sub.0 =.gamma. sin .theta..multidot.cos .rho., Y.sub.0 =.gamma. sin .theta..multidot.sin .rho. and Z.sub.0 =.gamma. cos .theta.. Therefore, a train of pulses (Hp) from a manual pulse generator are distributed as X-, Y- and Z-axial components in the proportion to the above values by a manual pulse distribution circuit, and motors for the respective axes are driven through servo circuits by the pulses.

    摘要: A shelf height selector system for a lift truck provides signals to an operator as he raises or lowers a load carriage relative to a storage shelf level selected by a keyboard in order to perform a store or retrieve operation, and automatically stops carriage movement with load forks at the proper elevation. Pulses from an incremental shaft encoder operated by carriage movement are counted to provide an instantaneous elevation signal upon which indications to the operator and control functions depend. A switch on the truck mast is operated by carriage movement to repeatedly recalibrate a register containing the instantaneous elevation signal, obviating any errors should noise affect tallying of encoder counts. An optical sensor carried on the load carriage to sense reflective markers adjacent some shelves also recalibrates the register, obviating positioning errors due to mast deflection and tire wear. Provision of a simple programming arrangement allows storage of shelf heights in a non-volatile random-access memory, affording the advantages of a field-programmable system.
