    Notes: When using programmed machine tools many steps of a shaft are machined in oneoperation. Many shafts are not rigid enough and for the purpose of achieving high accuracy andproductivity it is necessary to use an automatic follow rest and dimension control. The problem iscomplicated by necessity of an automatic reset in an operation from one step of a shaft to the other.The new scheme of a device is proposed in the paper that enables simultaneously to support theshaft being machined and control its dimensions. The work principle of a device is that the shaft issupported in a radial direction by a movable slider. Diameter of the shaft neck is measured by twolevers turning round their axes driven by the movable slider with patterns. The main idea is that atmotion of the slider equal to change of the shaft neck diameter measuring surfaces of levers areconstantly tangent to diametrical surface of the workpiece while the slider is supporting theworkpiece in radial direction, opposite to the cutting force. Dimension of a shaft neck is evaluatedas a sum of motion value of a slider and deviation from tangent of lever measuring surfaces.Theoretical background of principle schemes and the work scheme of a device are presented in thepaper

    Analysis of Work Accuracy Dependencies on Design of a Device for Control of Workpiece Dimensions and Compliance at Machining (2006)

    Notes: Work accuracy dependencies of a new scheme device for automatic dimension controland follow rest at machining of multi step shaft are analyzed. The device can automatically resetfrom control and the support of one step of a shaft to the other and can be used on programmedcylindrical grinders or lathes. Errors connected with the kinematics scheme and showing in staticand uprising at working of a device are analyzed and ways of their decreasing are shown

    Robotic Grippers with Accuracy Centering Fingers (2006)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: A new design scheme of a robotic gripper for rotational family parts is presented andanalyzed in the paper. The third or first class lever type of coupled fingers located from contrarysides of common longitudinal axis of symmetry of the gripper are used so that no less than twofingers from each side of the symmetry axis create an artificial centering prism. Distance of acenterline of the prisms, so the centerline of the part being handled, from the basic surface of thegripper is kept constant at changing diameter of the parts. Fingers are driven by a motion of slidersassembled inside of carriageways inclined to some angle to the symmetry axis of a gripper hand. Itis shown that by keeping some rates of dimensions of mechanism elements straight lined fingersurfaces will be kept tangent to the cylindrical surface of handled parts. Mathematical equationsdefining these rates are derived
