Multiple heat source-type preheating device for machining apparatus

Abstract

A multiple heat source-type preheating device for a machining apparatus is provided. The multiple heat source-type preheating device for a machining apparatus includes a first heat source provision module and a second heat source provision module. The first heat source provision module is installed to be moved along a portion of a material to be machined along with a spindle adapted to rotate a tool at high speed, and is configured to preheat the portion of the material to be machined by providing a heat source thereto. The second heat source provision module is installed to be moved along with the first heat source provision module, and is configured to preheat the portion of the material to be machined by providing a heat source thereto while preceding or following the first heat source provision module.

Description

BACKGROUND1. Technical Field[0001]The present invention relates generally to a preheating device, and more particularly to a novel multiple heat source-type preheating device for a machining apparatus, which is coupled to a spindle configured to rotate a tool at high speed and preheats a portion to be machined by the tool, and which can smoothly preheat the overall range of the portion to be machined by the tool while minimizing the output of a laser module used for the preheating.2. Description of the Related Art[0002]In general, methods using an external heat source for machining include two methods: ablation designed to directly use a heat source to cut a material; and thermally-assisted machining (TAM) designed to use a heat source for preheating intended to reduce the strength of a material.[0003]TAM of these methods uses a laser, and is applied to the cutting of a difficult-to-cut material. In connection with this, related technologies are disclosed in Korean Patent No. 10-147...

AI Technical Summary

Benefits of technology

The invention is a new device for a machining machine that has multiple heat sources. The goal is to prevent the temperature of the material being machined from quickly decreasing when the heat source supply is stopped, and to be able to smoothly preheat the material regardless of its properties, the range of the machining, and its depth.

Problems solved by technology

Meanwhile, a laser heat source used in the above-described conventional technologies is advantageous in that a material can be fast heated, but is problematic in that a heated material is rapidly cooled when the supply of the heat source is stopped.

Accordingly, during machining, phenomena occur in which a surface becomes rough and machining quality is degraded.

However, in this case, a new problem arises in that it becomes rather difficult to machine a material because the tool may be damaged or the physical properties and state of the material may be changed.
