摘要： Systems and methods for etching complex patterns on an interior surface of a hollow object are disclosed. A method generally includes positioning a laser system within the hollow object with a focal point of the laser focused on the interior surface, and operating the laser system to form the complex pattern on the interior surface. Motion of the laser system and the hollow object is controlled by a motion control system configured to provide rotation and/or translation about a longitudinal axis of one or both of the hollow object and the laser system based on the complex pattern, and change a positional relationship between a reflector and a focusing lens of the laser system to accommodate a change in distance between the reflector and the interior surface of the hollow object.

摘要： A wallet-sized comb is produced by a process of processing a metal substrate having a thickness similar to a credit card. The process includes receiving a comb design including a top portion and a teeth portion, the teeth portion including a plurality of spaced-apart teeth for combing hair and cutting the metal substrate based on the comb design, the cutting performed using a chemical etching technique, where the metal substrate has a thickness at or below 1.2 millimeter. The process further includes extracting a metal comb from the metal substrate generated from the chemical etching technique and de-burring the metal comb, as well as applying a powder coat finish to the metal comb to generate the wallet comb. The comb design may include a design and/or letters in the top portion, such top portion elements cut also using the chemical etching process.

摘要： Exposing nitinol to a shape setting temperature while the nitinol is in an unstrained or minimally strained condition. The nitinol is then substantially deformed in shape while at elevated temperature. After deformation, the nitinol remains at the elevated temperature for a time to shape set the material. The nitinol is then returned to approximately room temperature 20° C. by means of water quenching or air cooling for example.

摘要： A method for balancing a rotor, notably of a turbomachine, includes a step of determining an unbalancing mass, and a step of balancing by chemical machining of the rotor. The chemical machining includes arranging a bath containing a chemical machining agent so that the bath has a capacity of heterogeneous material removal as a function of the depth in the bath, an amount of material removal at a first depth in the bath is greater than an amount of material removal at a second depth in the bath; immersing the rotor in the bath; and orienting the rotor in the bath taking account of the capacity of heterogeneous material removal so that the quantity of material removed from the rotor in a zone of the unbalancing mass is sufficient to balance the rotor.
