Taiwan's machine tool industry, impacted by the depreciation of the Japanese Yen, faces price competition from both Japan and China. To overcome these challenges, domestic manufacturers must enhance the added functionality of their equipment and boost market competitiveness. The escalating issue of global climate change is driving countries to pursue Net-Zero Emissions by 2050, forcing companies to demand carbon reduction efforts across their supply chains. This makes energy-saving technology a critical competitive factor. Reducing energy consumption has become a key objective in the metal processing sector, requiring machine tool suppliers to integrate add-on software to help customers achieve carbon reduction goals. Consequently, the development of energy-saving technologies specifically tailored for machine tools is vital for future competitiveness.

According to Drone Industry Insights, the global drone market reached $30.6 billion in 2022 and is projected to grow to $55.8 billion by 2030, with a CAGR of about 7.8%. Additionally, the Drone Readiness Index ranks Taiwan second worldwide in regulatory preparedness, highlighting its strong competitiveness in both regulatory framework and industry environment.

台灣與日本同為地震頻繁之區域，地震對工具機與精密機械之水平精度監測則相形重要，本研究開發一套長時間水平量測與監測系統，如圖一所示。透過持續且高精度的數據蒐集與分析，評估地震活動是否造成機台水平偏移，進而影響加工與量測精度。並且了解與分析地震對精密機械穩定性的潛在影響，並為未來的地震補償技術與精密加工設備設計提供參考依據。本研究證實地震與CNC工具機之水平精度關係時，其影響程度甚是輕微，其水平精度皆於0.02mm/m，消除地震發生後對於機台可靠度下降之疑慮產生。

This article explores the positioning accuracy of Tsudakoma’s cradle-type tilting axis, measured using an angular swing inspection instrument. It compares the differences between enabling and disabling the angle encoder. Results show that when the encoder is enabled, positioning accuracy and repeatability are excellent, with compensated error reduced to 4.7 arc-seconds. When the encoder is disabled, non-linear errors occur within the ±10° range, reaching up to 155 arc-seconds. The study indicates that 1° incremental measurement can reveal structural characteristics, providing valuable reference for five-axis machine development.

This study investigates the accuracy of domestic five-axis machine tools, measuring linear axis six degrees of freedom, rotary axis positioning, circular interpolation, spatial diagonal accuracy, and tool-tip synchronous motion. Results indicate most machines meet ISO 10791 standards, with some achieving half the tolerance limits. Rotary axis errors are linked to geometric accuracy, rotary center alignment, and control parameters. Compensation and parameter adjustments are recommended to optimize precision and enhance machining quality.
