FrictiofusilisEst frictio inter duo metallis diversis compositionem et possessiones (Alloys), inter mollis metallum (workpiece) et durum metallum (mori). In casu de nulla lubricatae, est contactus frictio duarum generis metallum superficiem cadmiae, Under the lubrication condition, the contact friction between the oxide film on the two metal surfaces and the lubricating medium respectively, and the friction between the surface of the inner layer of the workpiece, which has not yet been oxidized and has a great adsorption force, Et frictio inter Lubricating medium et superficies mori et ipsam friction (contactus) area augendae.

Ob friction characteres inter blank et mori contactus superficies inprocessus, In his eventus erit;
(I) Force crescit per X% ex attritu et industria consummatio augetur secundum hoc;
(II) friction leads inaequale deformatio, ut et internum frumenti structuram et perficientur non uniformis, et superficiem qualis decrescit;
(III) friction ducit ad reductionem de geometrica figura et dimensional accurate de remittings, quae ducit ad exiguo remittings, cum Dolonos qui gravissime vacua;
(IV) friction leads ad aggravatur lapsum de mori et breviora ejus vita;
(V) augendae loci frictio resistentia cavitatis potest facere cavum quod est difficile ad satiata satiata metallum aequaliter et redigendum rejicere rate.
Potest videri quod frictio est a duplex ancipe gladio inForging productio, Quod habet et commoda et incommoda. Ergo frictio in colaging processus esse stricte imperium ad curare normalis colaphos processus.
