A cutting tool for cutting a hard brittle material is formed from a light-transmittable material through which laser light can pass and is provided with a rake angle, the laser light is propagated through the cutting tool, the cutting tool and the hard brittle material are brought into contact with each other, the laser light is incident to at least a contact part where the cutting tool and the hard brittle material are in contact with each other and a part with the rake angle, the laser light except for Fresnel reflection light on an end surface of the cutting tool is incident to the hard brittle material through the contact part and the rake angle part to soften the hard brittle material, and the softened hard brittle material is cut.

On at least one surface of a structural part, on all or part of a hollow section between outer and inner peripheral borders, is associated at least one cover sheet made of rigid metallic material. The at least one cover sheet is mechanically fixed with the edge of the peripheral borders of the structural part, and covers all or part of inner cavities formed on open sides of the part. The at least one cover sheet has a triple function: to increase the rigidity of the structural part, to absorb shock by deforming in a plane while remaining integral with the part, and to allow reduction of the mass of the structural part and optimization of the mass/performance ratio.

Techniques and devices are disclosed for fabrication layout device. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces are positioned on the pattern so that they can be assembled to one another.

Laser-assisted micromachining methods and systems capable of providing flexible beam positioning and low incident angles. Such laser-assisted micromachining systems preferably include a laser beam source, a cutting tool, means for engaging a workpiece with the cutting tool, optical elements arranged to define a path of a laser beam emitted by the laser beam source wherein the optical elements include at least a first mirror mounted in fixed relation to the laser beam source, and means for adjustably mounting a second mirror to project the laser beam onto the workpiece in proximity to the cutting tool and at an incidence angle relative to a surface of the workpiece.

A plate-shaped workpiece forming method of post-machining a pocket (3) on a curved inner surface of a plate-shaped workpiece (2) in a state where the plate-shaped workpiece (2) curved by a curving machine (10) is spread flat. The method includes a curving step (A) of setting a net curve radius (R.sub.0) obtained by adding a curve radius contraction amount (R.sub.1) due to spring-in to a finished curve radius (R) of a plate-shaped workpiece (2), taking into account an amount of contraction of the curve radius of the plate-shaped workpiece (2) between before and after machining of a pocket (3) due to spring-in, and curving the plate-shaped workpiece (2) so as to achieve the net curve radius (R.sub.0); and a pocket machining step of post-machining the pocket (3) by flatly spreading the curved plate-shaped workpiece (2).

A laser assisted micromachining system, includes a working sliding, a tool module, a laser module, and a temperature control module for the processing of a workpiece. The laser module is disposed in the working slide and moves with the working slide in three-dimensional space. The temperature control module includes a temperature sensor, a cooler, a controller and a coolant, which detects the real-time temperature value of the cooler. The cooler is located in the working slide and supports the tool module. The controller controls the working state of the cooler according to the temperature feedback. Control signal induced by the temperature indicator, and the working state of the cooler are controlled by the controller. The coolant is used to control the temperature distribution of the cooler in the setting range. At the same time, the invention also provides a temperature control method for the laser assisted micro machining system.
