在數值工具機切削加工的時候,精度不佳的的主要原因是由於力誤差、溫度誤差、幾何誤差及控制誤差所影響,本論文旨在設計出可以取代動力計計算測量切削力功能之智慧刀把,而智慧刀把可以透過感測器實時監控切削力及監測刀具的磨耗,進而減少加工時產生的誤差。因動力計價格高昂,無法大量使用於機台上,因此本論文研究計畫是要設計價格低廉但功能同於動力計,且不用更改CNC車床零件的智慧刀把。本研究使用壓阻式壓力感測器來當作是智慧刀把的感測元件,利用壓阻式壓電感測器進行資料的擷取與收集,同時利用電腦進行數據統合,再利用分析軟體繪製出切削力曲線,分析出車刀於切削時承受的切削力與車刀的磨耗,使得安裝此車刀之廠商可以減少車刀磨耗所造成的精度誤差,提高產品的競爭力。本研究結果可以得知,在切削紅黃銅C2300時,可以發現fc的誤差為5%以內,但f_(f )及f_p誤差都差超過10%;但是切削中碳鋼S45C,三軸切削力均小於5%,證實本研究之智慧刀把可以在實際加工做使用。且在實驗中可以發現,切削紅黃銅時車刀容易發生積屑的情況,進而產生誤差過大的情形,故本研究之車刀刀把適合切削材質較硬之金屬。
During numerical tool machine cutting, the main reasons for poor longitude are force errors, temperature errors, geometric errors and control errors. This paper aims to design a smart toolholder that can replace the function of a dynamometer to calculate and measure cutting forces. , and the smart toolholder can monitor cutting force and tool wear in real time through sensors, thereby reducing errors during processing. Due to the high price of dynamometers, they cannot be widely used on machines. Therefore, the research plan of this paper is to design a smart tool holder that is cheap but has the same functions as dynamometers and does not require changing the parts of the CNC lathe. This study uses piezoresistive elements as the sensing elements of smart tool handles. Piezoresistive sensors are used to capture and collect data. At the same time, computers are used for data integration, and analysis software is used to draw cutting force curves and analyze The cutting force and the wear of the turning tool endured by the turning tool during cutting allow manufacturers who install the turning tool to reduce precision errors caused by the wear of the turning tool and improve the competitiveness of their products. It can be seen from the results of this study that when cutting red buckwheat C2300, it can be found that the workpiece coordinates of f_(c ) are within 5%, but the f_(f ) and f_pworkpiece differences exceed 10%; but when cutting medium carbon steel S45C, three-axis cutting The average force is less than 5%, which proves that the smart knife studied can be used in actual processing. The turning tool holder studied is suitable for cutting harder metals.
