五軸工具機在多軸同動時會產生額外的誤差,造成較大的輪廓誤差,為了滿足高精度的要求,工具機必須經過調機補償以提升機台精度。五軸工具機再加入旋轉軸後,伺服匹配的問題會更加複雜,當旋轉軸有微小誤差時就會降低其加工精度,為了提升多軸工具機的精度,針對多軸同動誤差的研究變得相當重要。
本文量測系統利用雷射二極體與位置感測器當作主要量測元件,以雷射二極體視為刀尖點,而PSD視為工作台端,由MCU、ADC單晶片模組與藍芽晶片模組進行無線傳輸至PC端,透過程式分析資料。本系統優點在於可量測二維任意路徑與量測線性軸與旋轉軸同動誤差、成本低廉、架設簡便。
本論文研究目的是改良實驗室開發之量測設備應用於五軸工具機,此系統特色可以進行二維任意輪廓動態量測,和進行五軸工具機同動誤差量測,不需將量測儀器重新改變架設方式即可完成量測,減少重新架設所花費的時間。此儀器性能檢測:其原始訊號雜訊幅度約1μm之間跳動,此外其解析度可達1μm。雙軸動態循圓於不同進給速率下,100mm/min、500mm/min、1000mm/min、1500mm/min進給速率下,以半徑為1mm循圓測試,本量測系統在進給率100mm/min時,圓偏差值為0.0109mm,KGM量測圓偏差值為0.0085mm,在線性軸與旋轉軸同動量測下,於進給速率1000deg/min調整????????值後RMSE由原本3.0μm下降為2.5μm;真圓度由14.5μm下降為12.4μm。在任意路徑量測中,進給速率5000deg/min時誤差為6.0μm,進給速率10000deg/min時誤差為8.4μm,在移動路徑過程中可觀察出有靜點切削現象發生。
由各項量測結果中可知,本系統具有重複性且解析度可達1μm,可用於量測五軸工具機線性軸與旋轉軸同動誤差,量測加入旋轉軸之任意路徑為本儀器最大優勢,提供業界一簡易設備用於檢測機台動態精度。市售之量測儀器價格昂貴、架設與校正繁雜,且尚未有加入旋轉軸同動後任意輪廓的量測儀器。
The Five-axis machine tool in the multi-axis synchronous with each other will produce additional error, resulting in a larger contour error, In order to meet the high precision requirements, the machine tool must be adjusted to improve the accuracy of the machine, Five-axis machine tool and then add the rotation axis, the servo matching problem will be more complex, When the small error of the rotating axis will reduce its machining accuracy, in order to improve the accuracy of multi-axis machine tool, multi-axis synchronous error research has become very important.
In this thesis, the measuring system contains a laser diode and a position sensor, the laser point is represent as the tool center point, and the position sensor is represent as the rotary table. By the MCU, ADC single chip module and Bluetooth chip module for wireless transmission to the PC side, through the program analysis of information. The system has the advantages of measuring two-dimensional arbitrary path and measuring linear axis and the rotation axis with the error, low cost, easy to set up.
The purpose of this thesis is to improve the laboratory development of the measurement equipment used in five-axis machine tool, this system can be two-dimensional arbitrary contour dynamic measurement, and the five-axis machine with the machine error measurement, The instrument can be changed to set the way to complete the measurement, to reduce the time spent re-erection. This instrument performance test: the original signal noise amplitude between about 1μm beating, in addition to its resolution up to 1μm. In dynamic circle path test was measured at a feed rate of 100 mm / min, 500 mm / min, 1000 mm / min, 1500 mm / min feed rate at a feed rate of 100 mm / min, With a radius of 1mm circle path test, this measurement system in the feed rate of 100mm / min, the circular deviation of 0.0109mm, KGM measured circular deviation of 0.0085mm, The RMSE decreases from the original 3.0μm to 2.5μm at the feed rate of 1000 deg / min after adjusting the value of the linear axis and the rotating axis. The true roundness decreased from 14.5 μm to 12.4 μm, in any path measurement, the error rate is 6.0μm when the feed rate is 5000 deg/ min, the error is 8.4μm at the feed rate of 10000deg / min, and the static cutting phenomenon can be observed during the moving path.
From the results of the measurement, we can see that the system is repeatable and the resolution of up to 1μm, can be used to measure the five-axis machine tool linear axis and the rotation axis with the error, the measurement of the rotation axis of any path-based instrument Advantage, to provide a simple equipment for the industry to detect the dynamic accuracy of the machine. The commercially available measuring instruments are expensive, erected and calibrated, and have not yet been added to the contours of the rotating shaft.
