A laser-transmitting machining tool is disclosed. The laser-transmitting machining tool has a plurality of faces including an entrance face, a rake face, a flank face connected to the rake face, a rake side face extending between the entrance face and the rake face, and a flank side face extending between the entrance face and the flank face. The connection of the rake face to the flank face defines a cutting edge. The rake face extends away from the rake side face to define a rake angle. The entrance face is configured to receive and refract a laser beam to the rake face, the flank face, and the cutting edge for causing the laser beam to refract into and heat the workpiece at a compression region extending proximate at least the rake face and a tensile region extending proximate the flank face. A system for machining a workpiece is disclosed. A method for machining a workpiece is also disclosed.

Every junction part for an airplane wing is manufactured with overmaterial. Each part is measured with a laser based interferometer or other scanning technique and the as built measurements are compared with a model to generate a new trajectory milling program to fill or prevent gaps between parts using a points cloud and B-Spline algorithm to generate a new surface to be milled. Once the program is generated (new trajectories) and post processed, it is sent to a milling machine to perform overmaterial milling on already milled parts with overmaterial. This technique can be used to eliminate gaps between junction parts and the corresponding need for shims.

A system for duplicating a master key includes a mechanism for receiving and positioning a master key. The master key defines a major key axis and an intermediate key axis along which a key blade variably extends, and a minor key axis along a key thickness. Optical path components direct a light beam along the minor key axis. The light beam impinges upon the key blade. A portion of the light beam traverses the key blade. A detector receives the portion of the light beam that traverses the key blade. An apparatus imparts relative motion along the major key axis between the light beam and the master key. The light beam scans along the major key axis of the master key. A processor receives a signal from the detector as the beam scans along the major key axis and generates information usable for defining the machining of a duplicate key.

A variable-step-distance micro-milling repair cutter path generating method for damage points on a surface of an optical crystal related to a field of optical material and optical element surface repair and includes steps of establishing a mathematical model of a repair profile; determining discrete contact points between a cutter and the repair profile to obtain a cutter contact control point set by a GPR path generating method to control a movement trend of a pseudo-random path; interpolating the cutter position control point set into a spatial curve by a NURBS modeling method; creating a UG curve in a UG software according to the mathematical model, and using the UG curve as the repair path to perform a machining process simulation. The method has good elimination effects on cutter marks with constant period and improves the ability of the KDP crystal to resist strong laser damage.
