The present disclosure includes calculating coordinates of a midpoint of one of a plurality of first tool teaching points and the subsequent first tool teaching point, and calculating coordinates of a midpoint of one of a plurality of second tool teaching points that corresponds to the one first tool teaching point and the subsequent second tool teaching point, calculating an inter-midpoint distance between the midpoint of the first tool teaching points and the midpoint of the corresponding second tool teaching points, determining whether the inter-midpoint distance is within a given tolerance range, and reporting, when the inter-midpoint distance is out of the given tolerance range, the corresponding first tool teaching points and second tool teaching points as poor.

A method for optimizing forming processes for forming workpieces, in which information characterizing a relative position of a workpiece inserted in a forming device in relation to at least one reference point of the forming device is detected by means of an optical detection device, wherein at least one parameter for adjusting the respective forming process for forming the respective workpiece is determined during a respective forming process, depending on the information detected during the respective forming process and depending on the information detected during the previous forming processes performed prior to the respective forming process and stored in an electronic computing device.

A method and equipment for controlling a manufacturing process of a component of a tyre for vehicle wheels, wherein at least one continuous elongated element fed by a supplying member is placed on a forming support by means of at least one pressing member active on the at least continuous elongated element along an application direction. During the manufacturing of the component of the tyre, at successive sampling times T.sub.i, the value P.sub.i of a quantity indicative of the position of the pressing member is acquired along the application direction, where i is an integer greater than or equal to 1, T.sub.i=i*1/f, and f is the sampling frequency.

An incremental sheet forming system and method are configured to form a structure through an incremental sheet forming process. The incremental sheet forming system and method include a forming control unit that compensates for spring back of a structure to be formed through the incremental sheet forming process.

A wrinkle generation determination method for a press formed part includes acquiring, for each load ratio in in-plane biaxial directions, a relationship between an in-plane biaxial strain generated in a process of inducing out-of-plane buckling in a measurement part and a load, acquiring an in-plane biaxial strain at a point where a primary differential coefficient of an in-plane uniaxial strain on which a compressive load acts becomes local maximum as a stable behavior limit strain, and acquiring a stable behavior limit line that will be an index for wrinkle generation under a biaxial stress condition by plotting, on two-dimensional coordinates, the stable behavior limit strain acquired for each load ratio in a biaxial stress test in which a load in the in-plane biaxial directions is applied to a cruciform test piece for biaxial test so as to induce out-of-plane buckling in the measurement part.
