Description

technical field [0001] The invention relates to a numerically controlled thermal cutting processing system, in particular to a numerically controlled thermally cutting processing system installed on a three-dimensional motion control machine tool, and the processing material is a building prototype of foam plastic. Background technique [0002] In architectural design and planning schemes, it is necessary to use architectural models of corresponding proportions to show ideas. In the initial stage of mold release, the initial architectural molds made of polymer foam plastics are widely used. In many cases, the initial architectural forms are done by hand or made with simple linear cutting equipment. Therefore, the quality of the model is greatly affected by human factors, the production efficiency is low, the production cost is high, and the production accuracy of the model cannot be guaranteed, which is reflected in the rough surface of the first architectural model produce...

AI Technical Summary

Problems solved by technology

The thermal cutting machine currently used mainly increases the cutting efficiency by heating the metal blade. However, the heating area of ​​the metal blade is large and the heat is lost quickly, and the temperature is difficult to control. Therefore, the energy consumption is large and the difference between each cutting is large. resulting in poor precision

There are also a few cutting machines that use heating wires to cut, but they are only controlled by a single-chip microcomputer, and the heating wires can only move up and down or in a plane, and cannot realize three-dimensional processing, so their adaptability is poor.
