數位微型加工機人機操作介面的改善研究

目前台灣自製生產的家用微型工具機，或許是基於成本考量，機台的操控裝置大多是購入公用型的既有模組，同一組操控器可同時適用於不同形式的加工機台，例如木工雕刻機、雷射切割機…等。本研究選用一款國產的數位微型加工機(AXIOM Auto Route basic1)，針對其操作介面進行使用性分析，列出問題點並作改善提案，希望藉此改良操作介面，達到容易學習與操作的效果，讓台灣的微型加工機較能普及和推廣，產業也能更易於發揚光大。本研究是運用使用性研究手法中的實驗類績效評估法，讓受測者在觀察實驗室中進行特定典型工作項目的操作，觀察實驗室內架設有6台攝影機，以各種不同角度紀錄受測者的操作行為與指定工作項目的操作時間，並於受測結束後訪談受測者，針對機台操作的瓶頸與問題進行回溯記錄。結果發現由於手持操作器使用公用模組，在操控的文數字與圖像介面上多採混用型設計，同一按鍵必須肩負多種功能的操控，致使按鍵圖像標示不良、加工指令的辨識度不足、不易引導操作；此外，複合鍵操作程序複雜，也看不出相關性，不易記憶學習，大大降低操作者的學習效率與興致。本研究根據這些問題探討改善對策，改善其操作流程並建置APP介面操作的方式，來進行數位微型加工機的操作介面設計。本研究另外透過POP（Prototyping On Paper）軟體建構APP操作模擬情境來改善現行操作介面不易記憶與學習的缺點，再進行使用性評估比較其差異性，最後,我們以統計的方法進行T檢定，發現以APP改善的操作介面比現狀手操作器的操作模式在幾項典型工作項目之操作時間的縮短，獲得了很大的成效。另外APP介面操作的方式也比現狀手操作器的操作方式容易學習。未來透過本研究所得到的結論,可進一步設計將手機或平板電腦的APP程式利用藍牙或WIFI等無線傳輸方式,將控制碼傳送到加工機主機,實際可操控機器運轉,讓數位微型加工機更容易學習與操作,預期將會創造更廣大的市場。

At present, the domestic miniature machine tools produced in Taiwan may be based on cost considerations. Most of the control devices of the machine are purchased from the common type of existing modules. The same set of manipulators can be applied to different types of processing machines at the same time, such as woodworking carving. Machine, laser cutting machine...etc. In this study, a domestic digital micro-machining machine (AXIOM Auto Route basic1) was selected to analyze the operation interface of the user interface, list the problem points and make improvement proposals. It is hoped that the operation interface can be improved to achieve easy learning and operation. In order to make Taiwan's micro-machining machines more popular and popular, the industry can be more easily promoted. In this study, the experimental performance evaluation method in the use research method is used to allow the subject to perform the operation of a specific typical work item in the observation laboratory. The observation laboratory has six cameras and records the test at various angles. The operation behavior of the person and the operation time of the specified work item, and interviewed the test subject after the end of the test, and backtracking the bottleneck and problem of the machine operation. It is found that because the handheld operator uses the common module, the mixed design of the manipulated digital and image interface, the same button must be manipulated by multiple functions, resulting in poor button image marking and insufficient recognition of processing instructions. It is not easy to guide the operation; in addition, the compound key operation procedure is complicated, and the correlation is not seen, and it is difficult to memorize learning, which greatly reduces the operator's learning efficiency and interest. Based on these problems, this study explores the improvement measures, improves the operation process and builds the APP interface operation to design the operation interface of the digital micro-machine. In addition, the POP (Prototyping On Paper) software constructs the APP operation simulation situation to improve the shortcomings of the current operation interface, which is difficult to memorize and learn. Then, the usability evaluation is used to compare the differences. Finally, we use the statistical method to conduct T verification and find out the improved operation interface of APP has achieved great results in shortening the operation time of several typical work items compared with the current operation mode of the hand-operator. In addition, the way the APP interface operates. It is also easier to learn than the current operation of the hand manipulator. In the future, through the conclusions obtained by this research, we can further design the application program of mobile phone or tablet computer to transmit the control code to the processing machine host by using wireless transmission methods such as Bluetooth or WIFI. It can control the operation of the machine, making the digital micro-machines easier to learn and operate, and is expected to create a wider market.
