Precision mold found in the actual process it

The basic requirements for precision mold processing is to obtain a high precision, smooth surface quality parts, easy fine processing area. In the semi-finishing tolerances may be appropriate to transfer large, save computing time. In our experience, the choice of finishing tool is preferably less than the tool used, or gouging advance to avoid a collision when the finishing tool at the corner. In a sure case, leaving less margin cutting, finishing tool to facilitate the extension of life.
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.
