Analysis of cutting forces during grinding of titanium alloy and corrosion-resistant steel by diamond, electrocorundum and cubic borine nitrid wheels

The object of research is the process circular and surface grinding titanium alloy corrosion-resistant steel, namely, cutting forces arising from mechanical processing. One most problematic areas in work selection required modes, material wheel grain size. In course experiment, we used samples VT8 12Х18N9T on which was studied with wheels made various materials (electrocorundum, cubic boron nitride (CBN), diamond). values Py Pz were obtained latitude permissible are often flat grinding, can reach maximum values, respectively, Py=27 N, Pz=15.5 N. data at a low speed electrocorundum, about 15 m/s size 8. By reducing wheel, get effect increasing energy consumption process, due to increase forces. If compare different wheels, then following be noted. Compared electrocorundum when using CBN reduced by 20–25 %, diamond (despite high wear wheel), 25–30 %. This fact that conditions favorable for grains, makes it possible use more intense conditions. results study allow predicting performance production, also adjusting processing mode part obtain necessary quality indicators layer geometric dimensions part.
