Provided is a CNC machining device capable of more accurately measuring a shape of an object. The CNC machining deviceincludes a tool magazine, a spindle, an automatic tool replacing device, a CNC controller, a sensor headconfigured to generate measurement data corresponding to a distance from a surface of the object, and a personal computer. The sensor headgenerates measurement data (X, Z) at regular intervals. The CNC controllergenerates position coordinate data (x, y, z, xθ, yθ, zθ) at regular intervals. The sensor headtransmits the measurement data to the personal computerthrough first radio communication RC. The sensor headtransmits a synchronization signal for synchronizing the measurement data and the position coordinate data to the CNC controllerthrough second radio communication RC

CNC machining device

A method for calibrating a CNC processing apparatus is provided that can significantly reduce the amount of operation time required for sensor calibration. A method of the present invention for calibrating a non-contact sensor in a CNC processing apparatusincludes a first step, a second step and a third step. In the first step, the center coordinates of a reference instrument are measured with a contact probe and thereby the machine coordinates of the center of the reference instrument are determined. In the second step, after a non-contact sensoris mounted onto a spindle, the center coordinates of the reference instrument are measured only one time with the non-contact sensor, and thereby the non-contact sensor coordinates of the center of the reference instrument are determined. In the third step, calculations are made to determine the amount of displacement required to bring the non-contact sensor coordinates obtained in the second step into agreement with the machine coordinates obtained with the contact probe in the first step.

Method for calibrating CNC processing apparatus

Provided is a three-dimensional measurement device applicable to a machining machine. A sensor head contains a body and a collet chuck. A light emitting window and a light receiving window are provided on the front end of the body. A non-contact sensor is incorporated in the body. Laser light emitted by the non-contact sensor is radiated onto a workpiece through the light emitting window. Laser light reflected from the surface of the workpiece is received by the light receiving window. A collet chuck is attached to the rear end of the body. The collet chuck has the same shape as a collet chuck provided by each tool housed in a tool magazine of a machining center.

Three-dimensional measurement device

A non-contact laser triangulation scanning apparatus for generating a three-dimensional image of the surface of an object based on the 3D surface position and surface contrast information. The apparatus comprises a laser source, a first optical unit, a second optical unit, a photosensitive positional detector having a plurality of sensor elements, and an incident light measurement device. According to generated timing signals having a predetermined time interval, a reset timing of the sensor elements of the photosensitive positional detector is controlled. The incident light measurement device measures an amount of a certifying laser light after one timing signal. An amount of a measurement laser light is determined dependent on the measured amount of the certifying laser light. The three-dimensional image is generated by combining position data derived from signals of the positional detector with contrast data derived at least from signals of the incident light measurement device.

Apparatus for generating three-dimensional image of object

There is provided a construction for attaching an adjuster in which even if adjuster body attaching bolts are not sub-assembled, an adjuster body can be fixed temporarily to a pillar without the contact of a lock pin, which is provided at the tip end of an operating knob, with the pillar. The construction is such that a crank-shaped locking portion is provided at the intermediate portion of the adjuster body.
