The invention relates to a laser processing device that can change the diameter of a beam spot on an object to be processed, without using a mechanism for changing a distance between a condensing lens and the object. A beam emitted from a laser beam source is condensed by the condensing lens, and is made incident to an optical fiber. The beam emitted from the optical fiber is condensed by a condensing optical system onto an object to be processed. The object is welded using the condensed beam. The laser processing device comprises an adjusting unit that can change the angle of divergence of the beam on the emission surface of the optical fiber. The adjusting unit changes the angle of divergence of the beam, thereby to change the diameter of the beam spot formed on the surface of the object.

Laser processing device

Contact electrodes having a predetermined shape are formed by irradiating a laser beam onto the contact electrodes that are formed of a conductive material. The laser beam can be irradiated, after joining an end of each contact electrode opposite to a contact end to a contact board, so as to deform the contact electrode so that the contact end is located at a predetermined position. The laser beam may be irradiated while heating or cooling a portion of the contact electrode opposite to a portion onto which the laser beam is irradiated.

An injection mold design method for correcting a profile of a product to be fabricated into a releasable profile from a mold to design an injection mold based on a corrected product shape, utilizing a storage device for storing information of the product shape and mold profile, a display device for displaying the product shape or the mold profile on a screen based on the information read from the storage device, an input device for inputting designation information necessary for correction of the product shape or the mold profile, and a controlling device for unloading information of lines or planes being obstructive to correction of the product shape and the mold profile in the storage device in response to the designation information input by the input device. The method comprises removing lines or planes from the screen, and replotting the lines or the planes on the screen in terms of the information of lines or planes unloaded into the storage device after the correction operation of the product shape of the mold profile is completed.

Determining the intersection line of a plane Z=Z1 perpendicular to the axial direction of an end mill and a design surface, determining equal pitch offset-curves as path elements inside a material and outside the intersection line, determining intersection points crossing a material boundary from outside to inside as cutting start and end points and reverse respectively when going along the path, determining a tangent to the path element at the cutting start point and determining the intersection point of the tangent and a material boundary offset line outside the materials as the end mill approach start point. Determining a point at a minimum height on a design surface and determining such a ball end mill that a mill model does not interfere with the design surface when aligning the tip of the mill model with the point. When performing offset milling by a thickness .delta., making a mill model by reducing the outline of a rotating end mill by the thickness .delta., placing the model on the design surface to determine a path and actually cutting with the end mill along the path. Displaying a tree-type hierarchical menu and selecting one item of the lowest layer in the menu, resulting in selecting all related items in the hierarchical layers above it automatically.
