A laser projection method including the steps of: irradiating, from a laser projection unit, a workpiece that is a measurement object, with a laser while controlling a plurality of mirror angles; imaging the workpiece with a stereo camera, extracting a contour of the workpiece, and calculating a three-dimensional coordinate; calculating a positional relationship between the laser projection unit and the workpiece by comparing the calculated three-dimensional coordinate of the workpiece contour with the minor angle; and performing coordinate transformation of CAD data information and drawing CAD data from the laser projection unit to the workpiece, based on the positional relationship between the laser projection unit and the workpiece. The machining method including the steps of: selecting a component of a tool; assembling the component; imaging the tool assembled; and determining whether or not a desired tool has been assembled.

Method and apparatus for laser projection, and machining method

In order to easily verify an operation of the machine tool, a machining support apparatus includes a machining monitoring unit, a simulation processing unit, and a display unit. The machining monitoring unit, upon receiving a notification indicating detection of a simulation start code programmed in a machining program from a machine tool controller controlling a machine tool via a communication device, renders the machine tool controller to stop the machine tool. The simulation processing unitsimulates instructions from the simulation start code to a simulation end code in the machining program, while the machine tool is stopped. And the display unitdisplays a simulation performed in the simulation processing unit.

Machining support apparatus and machining support system

A method for detecting shapes that are undesirable for efficient processing and which occur from tolerance conversion by comparing a geometric relationship of shape elements obtained from shape data before tolerance conversion with a geometric relationship of the shape elements obtained from shape data after tolerance conversion. An inappropriate shape is identified when the compared geometric relationships are not the same.
