The single factor experiment was processed for the study on the effect of the cutting parameters on the TC17 titanium alloy surface roughness using the carbide tool on the condition of the high speed. The purpose is to provide the experimental references for the high speed cutting optimizing for machining of the titanium alloy blade or blisk. The sensitivity analysis for the cutting parameters show that the surface roughness is most sensitive to the feed per tooth, and less sensitive to the cutting speed and cutting depth.
The MoCN, MoSiN, MoAlN, and MoWN coatings are synthesized on the substrates of stainless steel or silicon (100) with reactive magnetron sputtering method by using Mo, C, Si, Al and W composite target. The microstructure of these fi lms were analyzed by XRD XPS SEMand HRTEM, and the hardness and oxidation resistance of these fi lms are characterized by nano-indentation and TGA. The results illustrate that the hardness and oxidation resistance of the MoN-based fi lms can be greatly enhanced through the nano-composite method and solid solution strengthening. Therefore, MoN-based hard coatings possess good comprehensive performance and would be applied widely in the aviation industry.
In order to achieve product plan for the composite digital production line and make it more operational, Based on the difference of material used to main process of production line, the composite production plan is departed in two stages: Partition plan and Machine plan. By analyzing project of aircraft composites workshop production plan, the methods are given to make partition plan and machine plan for composite components, and this system is taken into practices for composite workshop in digital production line. Practice shows that this type of approach can be effective during making practical production planning, and improve the ystem’s development, maintenance, and good scalability.
According to the problems such as incomplete information collection, feedback delay, lowlevel share of information during production process monitoring of manufacturing industry workshop, the workflow technology is introduced into process modeling and business drive, which can realize the automatic circulation of business process, the automatic collection and feedback of the information. The convenience of terminal application is enhanced by landing touch screen with reading card, and the monitoring results are displayed by using methods such as Gantt chart and so on. The production process monitoring system is developed based on the Primeton EOS middleware platform, which is applied in practical production.
