The article discusses the design, implementation, and testing of the accuracy of a measuring device used to measure the thickness of aircraft engine blades subjected to a robotic grinding process. The assumptions that the measuring device should meet were presented. The manufactured device was subjected to accuracy and repeatability tests using a standard workpiece. The analysis of research results proved that the measuring device exhibits an accuracy of one order of magnitude better than the accuracy required for blades. For control of the grinding process, the results should be perceived as appropriate. Then, the device was subjected to verification consisting in using it to measure the thickness of aircraft engine blades. The constructed device can be used, not only for inspection of final products, but also for control of the robotic grinding process because thanks to the output interface it can be used in the robotic station’s feedback loop.

Grinding Speed

There are lower grinding force and temperature in quick-point grinding process because of the higher grinding speed and the less depth of cut, especially the point contact between the grinding wheel and the workpiece due to the point grinding angles. Thus it can achieve better surface finishing process in grinding cylindrical surface. Since the point grinding model is different from the conventional cylindrical grinding in theory, the surface roughness is in relation to the point-grinding angles greatly besides the grain granularity, depth of cut, grinding speed and axial feeding rate like the conventional cylindrical grinding process. Based on the theoretical studies on the surface roughness in the process, the surface finishing experiments and measures at the various grinding parameters were performed. The experimental results show that the process parameters, such as point-grinding angles, depth of cut, grinding speed and axial feeding rate, must be controlled reasonably for the higher surface finishing demand in quick-point grinding process.

In non-circular contour grinding process, a theoretical model of constant linear velocity grinding has been established based on the X-C Axis linkage motion principle of grinding machine. Based on this theoretical model, a numerical calculation model, which can be used for practical grinding process and can optimize and regulate the grinding speed, has be built by way of cubic spline fitting interpolation method. The calculated numerical result of this model can switch into NC code of some NC system. According to the motion principle of grinding machine, the geometry information of specific non-circle contour part and the real parameter of the grinding processing plan, the corresponding NC Programming function also has been modularized. An experiment has been done on the NC high speed camshaft grinding machine type of CNC8312A, and obtained the ideal processing effect.At the same time ,it also shows that the proposed method has strong practical feasibility and great practical value.
