Numerical Controlled Process of Tube Sheet on Phthalic Anhydride Switch Condenser

摘要：

　　Phthalic anhydride switch condenser was imported,failure occurred many times after put in use.There are ellipsoidal winged tubes in them and the holes on tube sheet are ellipsoidal too,which is very difficult to manufacture.Established mathematics model,analyzed the mathematic relation,compiled NC program,realized the numerical controlled process of ellipsoidal hole on MITSUBISHI MCV-1700 machining center,and realized domestic manufacture of phthalic anhydride switch condenser.Analyzed the error of process and selected proper cutter too.Machining center was imported in 1990s,which CPU is only on 80386 levels,when the NC program is complex,the velocity of calculate will lower than the feed of end mill.The program is compiled with EIA code,which is difficult for most of engineers,took a common PC as program editor to compile program with Quick BASIC,then more technicians can compile program.This improved the procession of process and enlarged the range of machining center.
