Abstract: A system and a method for measuring the profile of a part. The measurement system includes a sensor with a probe having at least one degree of freedom, and a first reference element fastened to the probe. The sensor is arranged so that the probe is able to follow the internal or external contour of the part while the first reference element is outside the part. An imaging device is adapted to capture an image representing at least a portion of the outside of the part and the first reference element. Thus, the first reference element serves as a reference element for the position of the probe relative to the reference system that is the part.

The first structure defines a planar reference face divided up between at least a first portion whose surface is reflective according to a diffuse reflection, and a second portion whose surface is reflective according to a specular reflection, the second portion being divided up according to a series of localized zones positioned in the first portion. The second structure has an inclined face relative to the planar reference face. Applicable to three-dimensional optical measurement of the relative position between a first object and a second object.

Abstract: System for machining workpieces including a setting-up module and a machining module for the production of components. The setting-up module includes at least one first tool holder fixing device for fixing at least one tool holder removably, and at least one first workpiece support fixing device for fixing a workpiece support removably. The machining module includes at least one second tool holder fixing device for fixing at least one tool holder removably and at least one second workpiece support fixing device for fixing a workpiece support removably, such that the tool holder and the workpiece support can both be transferred from the setting-up module to the machining module after setting up.

Abstract: A lathe including a moving headstock designed to rotate and move forward a workpiece to be turned in relation to an axis of translation and rotation. A guide bush is designed to be attached to a frame of the lathe and includes a bush spindle and a clamping mechanism. The guide bush is designed to operate either in bush mode or in grip mode and is designed to be moveable axially in relation to the frame along the axis of translation and rotation. The lathe is arranged to operate in a first mode in which the guide bush is driven axially by the moving headstock, and a second mode in which the axial position of the guide bush is static in relation to the frame.

Abstract: A machining unit including at least one machining module. The machining module includes a protective compartment that delimits an enclosure and has a front door, which can go from a closed position to an open position defining an opening. A machining assembly is provided with a tool-holder and a part-holder. A movable carriage receives the machining assembly and can slide on a guide device, between a first position in which the machining assembly is accommodated in the enclosure and a second position in which the carriage projects from the protective compartment via the opening and the machining assembly is situated outside the enclosure. In the first position, the front door can be closed for the purpose of carrying out machining of a part by the machining assembly. The second position permits access to the machining assembly from the exterior of the protective compartment.

Abstract: A method of creating an undercut sidewall profile within an opening formed in a positive resist layer disposed upon a transparent substrate includes the step of forming a positive resist layer on the upper surface of the substrate, and optically patterning the resist layer by selectively directing light at the resist layer from above the upper surface of the substrate. The lower surface of the substrate is flooded with light to partially expose the lowermost region of the resist layer, and the exposed resist is dissolved to form patterned openings therein. The resulting sidewalls of the patterned resist openings have an enlarged width adjacent the upper surface of the substrate. The sidewalls of the resist layer are then flooded with light from above the substrate, the upper region of the resist layer is cured by an electron beam, and the resist layer is developed a second time to dissolve exposed portions of the resist sidewalls, thereby forming an undercut resist sidewall profile.
