This Small Business Technology Transfer Research (STTR) Phase I project will establish the feasibility of commercialization of CHT (Computer-aided Heat Treatment) technology developed at the Worcester Polytechnic Institute (WPI). The proposed research will: (1) develop knowledge discovery based data mining tools to uncover hidden furnace model parameters and rules; (2) develop a calibration technique to enable furnace profiling for each individual furnace which will improve model accuracy; (3) develop a web-based service model to enable broad customer beta use of the tools; and (4) convert the current CHT systems into web-based systems to facilitate the service oriented business model. Heat treatment process is a manufacturing process which determines the materials properties contributing to the product quality. Under WPI Center for Heat Treating Excellence (CHTE) sponsorship, a loaded furnace modeling technique has been developed for simulating the complex thermal process and microstructure evolution for predicting material properties. The models have been validated with production data. This approach can be further used to optimize heat-treating processes, improving energy efficiency, reducing process times and production costs, and achieving zero distortion and uniformity in heat-treated parts.

这项小型企业技术转移研究（STTR）第一阶段项目将确定伍斯特理工学院（WPI）开发的CHT（计算机辅助热处理）技术商业化的可行性。研究方向为：(1)开发基于知识发现的数据挖掘工具，发现隐藏炉模型参数和规则；(2)开发一种校准技术，以便对每个单独的炉进行炉形分析，这将提高模型的准确性；(3)开发基于web的服务模型，使广泛的客户试用这些工具；(4)将现有的CHT系统转换为基于web的系统，以促进以服务为导向的业务模式。热处理工艺是决定产品质量的材料性能的制造工艺。在WPI热处理卓越中心（CHTE）的赞助下，开发了一种加载炉建模技术，用于模拟复杂的热过程和微观结构演变，以预测材料性能。这些模型已经用生产数据进行了验证。该方法可进一步用于优化热处理工艺，提高能源效率，减少工艺时间和生产成本，实现热处理零件的零变形和均匀性。
