Precision molds in the actual machining process found that when using a conventional fixed-axis milling, such as selecting the UG default circular interpolation mode {circular-perp to TA}, PTP output file size will be larger, especially if you choose 45 degrees finishing. On the pre-reading skills somewhat less machine, if you use a high feed rate, the surface will produce shades of eating knife phenomenon, so that the surface roughness dropped significantly. In repeated experiments, we find out a suitable solution, the choice of another circular interpolation mode UG provided [circular-perp / par TA}, after treated in this way greatly reduce file ptp small, so that pre-reading machine to reduce the load, it can easily maintain a very high quality surface finish and at higher feed rate.

We used fixed-contour the area-milling finishing half way when habits on part of which is particularly suitable. It can maintain a very consistent along the upper surface of the cutting line spacing, complete will all face when roughing brought marks do a complete removal, to ensure the stability of the finished load.
