Summary: In producing treatment course, the stress of the spare parts is accompanied in all sorts of treatment, in the internal composition of consist in workpiece. Below special situation, some prestressing force are beneficial, but fall in most circumstance, the stress of workpiece interior is harmful. The existence of workpiece internal stress is light person make workpiece is out of shape, serious when the fatigue life that can lower workpiece causes an accident, but the application that adopts technique of oscillatory effectiveness for a given period of time, very good settlement the stress problem of workpiece interior, make workpiece interior stress is eliminated permanent be out of shape no longer. Keyword: Internal stress of oscillatory effectiveness for a given period of time is out of shape 1, a kind of rod that my factory produces preface kind in canister body spare parts, slot of a semicircle opened on the axis, the workpiece after opening slot is out of shape via examining to have 100 percent, by blueprint the requirement does not have an eligible product. Because the internal stress of the workpiece after treatment is caused evenly afresh,this is, and axis kind canister body spare parts cannot undertake again corrective, so this is the long-standing problem that my factory produces. Pressing craft to machine this to be able to have two kinds of methods, 1, open slot first, the circle outside be being machined and inside Kong Dingcun. Machine what can eliminate work to be out of shape so problem, but because opened groove to had obtained central line,be in, aperture of place less than is machined special difficulty, make sure blueprint asks very hard. Treatment of the circle outside Kong He is decided inside inch, next reopen chamfer. Such inside round treatment can make sure blueprint asks outside Kong He, but hind of workpiece opening slot be out of shape insoluble. Join the real case that my factory produces, a kind of method after we were used. 2, make treatment program first selection the problem of stress of interior of the workpiece after we should solve treatment, if workpiece interior does not have stress, workpiece won't be out of shape, must eliminate the internal stress after workpiece is machined so. If use hot effectiveness for a given period of time, because workpiece has been machined,decide inch, workpiece surface cannot have oxidation, and workpiece of hot effectiveness for a given period of time still has be out of shape, so we use oscillatory effectiveness for a given period of time. One, vibration also removes ground of blame Chang Che without oxidation surface, stress, 2, the workpiece vibration effectiveness for a given period of time after finish machining also was not out of shape. So we use the method of advanced and oscillatory effectiveness for a given period of time. On workpiece we also take a few necessary step, the semicircle chamfer that attends work first debuts not completely, a muscle that does not add stayed in round central part, as first rough machining is same, have oscillatory effectiveness for a given period of time next. 3, we used device of effectiveness for a given period of time of vibration of oscillatory effectiveness for a given period of time Beijing circle in the air the navigate that finite liability company manufactures rich science and technology person " vibration eliminates stress expert system " , this equipment is in every time when workpiece is handled, intelligence chooses oscillatory parameter, the system is optimized automatically choose frequency of 5 above vibration, multidimensional eliminate leftover stress; And this equipment noise is very low, it is the product of green environmental protection that can remove workpiece remains stress completely. We work all tigidity is approached on platform, OK and oscillatory many. 4, after conclusion vibration effectiveness for a given period of time, we are machined in that muscle that attends work. Via examining, workpiece brace up before and brace up the precision after agrees completely. That is to say, workpiece brace up before and brace up after was out of shape do not have, we made similar test to 3 workpiece again later, effect just the same, we perfected technology finally, all work that process by this craft 100 ％ are eligible, solved the problem of the long-standing that factory perennial produces. This is technology of oscillatory effectiveness for a given period of time in me the clever application in factory production. CNC Milling CNC Machining
