For a good finish reduce the cutting depth to around 0.05 mm, use plenty of lubricant and make sure that the tool is realy sharp. I would run at a lower speed than 200 rpm (around 50-100 rpm). Finally, in order to reduce the medium frequency error of "knife-like grain", the control parameters of the aerostatic spindle are reasonably optimized based on the analysis of the mechanical and electrical coupling control performance of the spindle, so that the RMS values in the medium frequency band of the workpiece are greatly improved after machining. The tool should be ground like a right hand lathe cutting tool with a slight radius at the tip. Then, the variation rule of the cutting amount caused by the fluctuation of spindle speed is explored theoretically and experimentally, and the formation mechanism of medium frequency error in flycutting is revealed. Fly-cutting is a process in which the diamond tool tip is on an air bearing spindle and is rotating very fast. Secondly, through the frequency domain waterfall diagram of vibration signal and the analysis of spindle speed signal, it is proved that the surface shape characteristic is caused by the fluctuation of spindle speed during the cutting process. Besides, the error traceability is realized and the results show that the periodic low-frequency fluctuation of 0.3 Hz between the tool tip and the workpiece is the cause of the medium frequency error of "knife-like grain". In this paper, firstly, the characteristic phenomenon of "knife-like grain" in the medium frequency surface of the square and circular optical crystal machined by ultraprecision fly-cutting is revealed. NET Framework Version:9 ASP.NET Version.The medium-frequency error on the surface of ultraprecision flycutting has an important effect on the performance of the optical crystal. Checking my last spoilboard surfacing file (using a similar bit) our 5-HP spindle used: - depth of cut 0. Common edge cutting reduces the length of the cut and significantly improves the efficiency of the process. Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) +13992992 As always, such things depend on the robustness of your machine frame and spindle. If the contours of adjacent parts have straight edges and the same angle, they can be combined into a single straight line and cut only once.
