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约有30％是金属去除（加工），除了少数例外，从地球上提取并在加拿大经济各个领域中加工成制成品的所有物品都需要直接或间接加工。在可预见的未来，加工是并且将继续成为制造业中最重要的基石之一。 By nature, machining research is highly 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和穿着现象。解决这些苛刻的条件需要表征和理解材料和工具之间发生的相互作用。******在MMRI的金属切割研究领域，由于工具的磨损非常困难，因此过去的大部分工作都是在工具上完成的，因此对加工过程的现场表征极为困难。利用该领域的20多年的经验，MMRI一直在研究实验设置，该设置使现场表征成为可能。实验设置已得到证明，现在使用高速视频收集了重要的数据，以以前从未做过的方式来表征毫米大小的“切割区”。****据我们所知，MMRI是世界上第一个以这种方式表征金属切割的研究小组，但是我们目前缺乏一种强大的在Situtus In-Situ中的强大方法。为了成为世界上第一个以这个方向发布新颖的结果，我们迫切需要一个热成像系统，这是衡量应用中温度的唯一可行方法。这些工具的磨损和性能由切割区的温度和压力控制，导致化学和物理磨损。工程工具可以更快地切割和持续很长时间，需要对化学和物理磨损机制有详细的理解，这些机制高度复杂，由于直接观察这些机制的极端困难而无法完全理解。热成像系统将使MMRI的50多名研究人员能够在研究实验中的能力来测量温度并更好地了解物理和化学磨损的基本驱动因素。
