Approximately 30% of all metal product manufacturing activity in Canada is metal removal (machining) and, with few exceptions, everything extracted from the earth and processed into manufactured products across every sector of Canada's economy requires machining, either directly or indirectly. Machining is and will continue to be one of the most important cornerstones of manufacturing for the foreseeable future.******Our team at the McMaster Manufacturing Research Institute (MMRI), led by Dr. Stephen Veldhuis, have an extensive history in advanced manufacturing research with a specific focus in machining. By nature, machining research is highly applications based and has led to very strong partnerships between the MMRI and industry, ensuring MMRI research thrusts are working towards developing knowledge, techniques and technologies that lead to valuable solutions for industry.******In difficult to machine materials like titanium and Inconel, the millimetre sized “cutting zone” is subjected to local pressures exceeding 2 GPa and temperatures exceeding 1000ºC, resulting in severe chemical and physical wear phenomena. Addressing these demanding conditions requires the ability to characterize and understand the interactions occurring between the material and tool.******In the MMRI's field of metal cutting research, the majority of past work has been done on tools after they are worn out due to the extreme difficulty of in-situ characterization of machining processes. Drawing on over 20 years of experience in this field, the MMRI has been working on an experimental setup which makes in-situ characterization possible. The experimental setup has been proven and important data is now being collected using high-speed video to characterize the millimetre sized “cutting zone” on cutting tools in a way never done before.******To the best of our knowledge, the MMRI is the first research group in the world to characterize metal cutting in-situ in this way but we currently lack a robust method to measure temperatures in-situ. To be the first in the world to publish novel results in this direction, we are in critical need of a thermal imaging system which is the only feasible way to measure temperatures in our application.******In industry, the productivity, quality and cost of machining processes is greatly impacted by the performance of metal cutting tools. Wear and performance of these tools is governed by the temperatures and pressures in the cutting zone, leading to chemical and physical wear. Engineering tools to cut faster and last long requires a detailed understanding of the chemical and physical wear mechanisms, which are highly complex and still not fully understood due to the extreme difficulty of observing these mechanisms directly. A thermal imaging system will allow the MMRI's over 50 research personnel to greatly improve our ability in research experiments to measure temperature and better understand the fundamental drivers of physical and chemical wear.

加拿大所有金属产品制造活动中大约 30% 是金属去除（机械加工），除少数例外，加拿大经济各个部门从地球中提取并加工成制成品的所有物品都需要直接或间接机械加工。在可预见的未来，将继续成为制造业最重要的基石之一。 *****我们麦克马斯特制造研究所 (MMRI) 的团队由 Stephen Veldhuis 博士领导，在先进技术方面拥有丰富的历史本质上，加工研究是高度基于应用的，并导致 MMRI 和行业之间建立了非常牢固的合作伙伴关系，确保 MMRI 研究重点致力于开发知识、技术和技术，从而为客户提供有价值的解决方案。 ******在钛、铬镍铁合金等难加工材料中，毫米级的“切削区”承受着超过2 GPa的局部压力和超过1000℃的温度，导致严重的化学和物理磨损现象。解决这些苛刻的条件需要能够表征和理解材料和刀具之间发生的相互作用。******在 MMRI 的金属切削研究领域，过去的大部分工作都是在磨损后的刀具上完成的由于加工过程的原位表征极其困难，MMRI 凭借在该领域 20 多年的经验，一直在研究使原位表征成为可能的实验装置。该实验装置已被证明是重要的。现在正在使用高速收集数据视频以前所未有的方式表征切削刀具上毫米大小的“切削区域”。******据我们所知，MMRI 是世界上第一个表征金属原位切削的研究小组通过这种方式，但我们目前缺乏一种可靠的方法来测量原位温度。为了成为世界上第一个在这个方向上发表新颖结果的人，我们迫切需要热成像系统，这是唯一可行的测量方法。我们应用中的温度。*****在工业中，生产力、质量加工过程的成本很大程度上受到金属切削刀具性能的影响，而这些刀具的性能受切削区域的温度和压力的影响，导致工程刀具需要更快地切削和更持久的切削。详细了解化学和物理磨损机制，这些机制非常复杂，而且由于直接观察这些机制极其困难，目前尚未完全了解，热成像系统将使 MMRI 的 50 多名研究人员大大提高我们的研究能力。测量温度并更好地了解基本原理的实验物理和化学磨损的驱动因素。
