“…In the last two decades, in order to reduce the wear of broach and increase its lifespan, improve the surface precision of the workpiece [ 6 ], researchers have put much effort into optimizing the parameters of broaching tools, such as the modification of geometric model for the broaching tools [ 7 , 8 ], optimization parameters of rake angle, clearance angle and rise per tooth (RPT) [ 3 , 9 , 10 ]. Klocke et al [ 11 ] used carbon free cutting material MC 90 to replace the speed steel for broach tool, which processed a higher hot hardness and increased thermal conductivity.…”

In order to improve the keyway broaching process and verify the feasibility of vibration-assisted broaching process, an experimental study on a novel hydraulic vibration assisted broaching (HVAB) system with double-valve electro-hydraulic exciter (DVEHE) is proposed in this paper. The performances of HVAB at different excitation frequencies were compared from three aspects: (a) the cutting force under the different vibration frequencies, (b) the surface roughness of the workpiece, and (c) the flank face wear of the tool. For precision on-line measurement of larger broaching forces, four piezoelectric sensors were fixed on the broaching machine. The experimental results show that HVAB can effectively improve the performance of the broaching process, approximately reduce the broaching force by as much as 9.7% compared to conventional broaching (CB) and improve the surface quality of workpiece. Some explanations are offered to support the observations.

“…The deformation is determined from the following formula for ring attachment at the internal surface in a three-jaw clamp by the method in [5][6][7][8] where R is the mean ring radius, m; E is the elastic modulus, GPa; J xy is the moment of inertia, cm 4 ; α is the angle (deg) between cross section 1-1 (Fig. 5) and the cross section for which the error is determined.…”

Static Error in the Depth of Internal Screw Channels Produced by Composite Mandrels

2021

View full text Add to dashboard Cite

The existing profiles of internal screw channels are reviewed. Formulas are proposed for the static error in the channel depth due to elastic deformation of the walls of the cylindrical shell in cutting. (Shells of steel 45 and BrAZh9-4 bronze are considered.) An approach is outlined to determining the static error in machining helical channels by a mandrel with one and three cutting teeth. The error in the cutting depth is plotted as a function of the cutting speed with different wall thickness of the cylindrical shell.
