Abstract
This invention relates to a process for manufacturing, shaping, and machining of a part made of a shape memory alloy, comprising a single step in which the said part is fabricated, shaped and machined simultaneously in a single operation by a cutting machining process such as turning. The invention is also related to the part prepared by this process, which is particularly a helical spring with adjacent turns. In particular, this part may be used in actuator or actuator/sensor type devices.
Claims15
Process for manufacturing, shaping and machining a part made from a shape memory alloy, comprising a single step during which the fabrication, shaping and machining of the said part are done simultaneously in a single operation by a cutting machining process, in which one or several operational parameters of the cutting machining process is varied in order to make a uniform and continuous part in the form of a chip from a metallic blank of shape memory alloy, said chip having desired mechanical and/or functional properties.
