The invention discloses a
machining method for improving the precision of a
triangular prism surface, which comprises the following steps of: establishing a three-dimensional model, importing the three-dimensional model into UG
software, setting cutter parameters in an equal-height finish
machining mode, then respectively setting rough and finish milling parameters, and exporting a rough milling program and a finish milling program. And in the finish-milling procedure, the
smooth surface is milled at uniform acceleration, the speed is uniformly reduced when the cutter is fed to the
ridge surface, and the cutter passes through the
smooth surface at uniform acceleration after passing through the
ridge surface, and the steps are repeated in sequence until a circle of
triangular prism surface is machined. The precision and the surface quality of the
triangular prism surface are improved, the
machining efficiency is higher, and production is convenient.
