在這科技日益精進的競爭下,積極推動電腦輔助研發工程的技術,結合電腦軟體技術於產品設計、分析與製程的趨勢,將產品走向高品質、低成本與短開發時間構面的要求。市面上小型雕刻機的結構皆為焊接而成,對於只能輕切削牙雕機在機構上是有足夠強度的,因切削陶瓷材料上結構須具有較高的穩定性與焊接的吸振能力具有一定差異,且製造上成本亦是考慮的因素。 牙雕機五大部件結構主要搭配模組化傳動元件作設計,以板肋幾何排列方式、尺寸厚度及箱體設計理念,建立出整機結構,並探討結構件包括傳動元件與結構機身組立後,機台整體的自然頻率及剛性。在結構力流的傳遞上,亦須考慮結構應力集中部分,則以更改肋的尺寸以克服牙雕機在進行脆硬陶瓷切削時應力集中的影響。 本文藉由開發牙齒雕刻機,修改結構設計以提高結構件的自然頻率,使之不易被激振而產生變形,影響精度。設計中藉由有限元素分析軟體進行模態、靜態及剛性分析,了解結構振型,來判斷結構中較脆弱需補強的部位,作修改補強設計。 雕刻機結構模型經由翻沙鑄造及加工後進行組立作業,將鑄件、傳動元件與控制器作機電整合,三軸向經雷射干涉儀檢測,軸向精度控制在5μm內,並以實際切削陶瓷及碳鋼作測試,實現牙雕機精密切削。
Summary he technology is increasingly sophisticated competition, actively promoting the technology of computer-assisted research and development projects, combined with computer software technology in product design, analysis and process trend toward the requirements of high-quality, low-cost and short development time dimensions. Small engraving machine of the market structure are welded for only light cutting tooth engraving machine institutional sufficient strength, with some differences due to the cutting ceramic materials require high stability and welding vibration absorption capacity and manufacturing cost is also a factor to be considered. The tooth engraving machine five parts structure with modular drive components for the design, geometric arrangement Rib, size, thickness and cabinet design philosophy, the establishment of the whole structure, and to explore the structural components including transmission components and structure of the fuselage assembly. The natural frequency and the rigidity of the machine overall. Structural force flow to pass on, to be taken into account when the structure stress concentration part by changing the size of the ribs to overcome the effects of stress concentration tooth engraving machine during hard brittle ceramic cutting. This article by developing teeth engraving machine, modifying the structure designed to increase the natural frequency of the structural member, so that excitation and easily be deformed, affecting accuracy. Design by finite element analysis software modal, static and rigid analysis to understand the structure of shapes to determine the structure more vulnerable and need reinforcement parts modified reinforcement design. Structural model via engraving machine assembly operations over sand casting and machining, castings, transmission components and controller for the mechanical and electrical integration, three-axis laser interferometer detection axial precision control within 5μm, and the actual cutting ceramic and carbon steel for the test, the tooth engraving machine precision cutting.
