A method for assisting an operator in operating a machine. The method includes receiving, by a controller, a selection of a task of a plurality of tasks, each task associated with a corresponding movement pattern of the machine; sensing, by a sensor unit, at least one condition of at least one component of the machine associated with the selected task; and determining, by the controller, whether the condition is within a predetermined set of parameters associated with the selected task. In response to determining that the condition is not within the predetermined set of parameters, the method further includes generating, by the controller, an audible or a haptic signal associated with at least one of the condition or the at least one component.

Method for assisting or training operators to operate machines

An apparatus for the heat-treating of a heat-hardenable steel cruciform article having a weld seam includes a heating element to heat the weld seam to a point that an austenitic transformation occurs, and a quenching chamber to cool the weld seam, causing the formation of Martensite and an associated expansion. The quenching is rapid since slow quenching may allow a crystalline phase other than martensite to form. The apparatus may comprise rollers operable to convey the welded cruciform article through the apparatus at a speed such that the weld seam is subjected to heating for a predetermined heat time sufficient to cause a formation of martensite there within, and such that the heated portion reaches the quenching chamber and is quenched to create a substantial amount of martensite, e.g., an amount sufficient to cause expansion of the part.
