Abstract

Provided are a method and device for automatically setting a relative position relation between a tool post of a numerical control (NC) machine tool and an edge of a tool mounted on the tool post and fully automating work of setting a tool offset value of a machine tool in which multiple tools are used. Tools mounted on tool posts are measured by cameras or laser length measuring devices. A temporary tool offset value is set using shape data of the tool and data indicating a direction of an edge of the tool designated to a machining program and / or tool data registered with a controller. The edge of the tool is automatically brought into contact with a tool setter using the temporary tool offset value. Thereby, the accurate tool offset value is acquired and set for an NC device. It is possible to simulate a machining operation using the temporary tool offset value or to check interference using the shape data of the tool which is acquired by the camera or the laser length measuring devices.

Description

technical field

[0001] The present invention relates to a method and an apparatus for automatically setting a relative positional relationship between a tool post of an NC (numerically controlled) machine tool and a head of a tool mounted on the tool post. The present invention relates to the above-mentioned method and device suitable for a CNC (numerical control) lathe equipped with a plurality of turret tool holders and an automatic tool changer. Background technique

[0002] The CNC machine tool processes the workpiece by controlling the position of the tool holder according to the instructions of the processing program. However, since the cutter head of the tool mounted on the tool holder actually processes the workpiece, if the relative positional relationship between the position of the tool holder and the cutter head is not known, the workpiece cannot be processed into a correct shape.

[0003] Therefore, after the tool is mounted on the tool post, for each tool moun...
