Abstract: An exemplary device, for the support and rotary transfer of one or more parts, is integral with an operating shaft whose movement is brought about by the relative displacement of a transverse finger connected to the shaft on a cam-forming path. The exemplary device includes a means for moving the operating shaft translationally, which is free in axial rotation and equipped with a finger extending radially, which moves along a stationary path so that the translational movement of the shaft also ensures its rotation via the passage of the finger inside of the path, the finger moving inside a shaped track provided in a stationary cylinder called a cam cylinder, inside of which the operating shaft moves.

Abstract: The invention concerns a measuring method applicable to a machine-tool (M) which consists in causing the tool (O) to contact a point selected as reference in the machining station by controlling said actuating means (200) which, through exceeding a force value defined as threshold, triggers the measurement so as to find out the value of the stroke performed and in repeating the operation to compare the values and to correct the values during the performance of the machining process. The invention also concerns the tool for implementing the method and the software product controlling same. The invention facilitates measurement on a machining station, integration of expansion phenomena, and measurement of the workpiece for the purpose of orientation.
