摘要： A method of and apparatus for forming chamfers in an orifice of a workpiece. The orifice has an axis, which extends between a first surface and second surface of the workpiece, where the first and second surfaces are parallel to each other. The chamfers are disposed between the first surface and the second surface. The method includes forming an orifice in a workpiece with a source of non-collimated light directed at the workpiece at a predetermined first time interval, and forming a chamfer with a source of collimated light at a second time interval during the first time interval. The apparatus includes at least one source of collimated and non-collimated light, various spatial filters that can be used with the laser light source, a non-collimated light generating arrangement, and at least one shutter and at least one iris that direct collimated and non-collimated light at the workpiece to form the orifice. The apparatus is configured such that the orifice has a surface roughness of between approximately 0.05 micron and approximately 0.13 micron and a coefficient ratio of at least approximately 0.

摘要： A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased.

摘要翻译： 一种用于调整断路器跳闸机构的校准的方法，该断路器跳闸机构包括端子元件，与其连接的双金属元件和跳闸杆。 将激光能量施加到端子元件的拉伸或预弯曲表面以热引起其位移，从而改变双金属元件和跳闸杆之间的跳闸距离。 在激光束被引导落到终端元件的拉伸或预弯曲部分的中间腿部的情况下，双金属元件相对于跳闸杆在一个方向上移动。 相反，当激光束被引导落到端子元件的拉伸或预弯曲部分的侧向腿上时，双金属元件相对于跳闸杆沿相反方向移动。 因此，不管是否增加或减少跳闸时间，激光能量可以从同一方向或跳闸结构的同一侧施加。
