Effect of Cutter Shape on the Resistance of PDC Cutters Against Tip Impacts
SPE Journal, 2022Summary Under harsh downhole conditions, the quasibrittle characteristics of polycrystalline diamond compact (PDC) cutters are a serious drawback, which readily causes the cutters’ premature failure under impact loads. Innovating 3D cutter shapes is an effective solution for optimizing the cutter’s interaction with the rock and improving

Selecting the Shape of the Insert in a Lathe Cutter
Russian Engineering Research, 2019Attention focuses on the selection of a removable polyhedral insert with recommended geometry of the cutting element, when the tool material meets the requirements of intermittent cutting. Shaping of the cutter’s front surface to intensify machining is also considered.

On the shape of backed-offmilling cutters
Flow, Turbulence and Combustion, 1949Some general considerations are given about the shape of backed-off milling cutters. When the back-off curve is given, one of the three shapes of profile, wanted profile and shaving surface can be found, provided the other two are known. A formula is derived for the case where two of the three above mentioned figures are either straight or plane and ...

INTRODUCING NEW VITREOUS CUTTER BLADE SHAPES
Retina, 2014To assess the efficacy of novel vitreous cutter blades compared with the regular guillotine by means of particle image velocimetry. Tested blades included a regular blade (RB) and newer designs where a circular (hole blade [HB]) or a slit aperture (slit blade [SB]) had been opened proximal to the cutting edge.Twenty-three-gauge probes were immersed in ...

TURNING MODEL FOR SHAPED SURFACES WITH OPPOSITE CUTTERS
Fundamental and Applied Problems of Engineering and Technology, 2021The analysis of the technological scheme of double–cutter shaped turning with opposed placement of cutters is carried out. An unstable form of oscillations of the cutter – workpiece system during turning is considered. Dependences are presented that allow estimating the magnitude of oscillations during processing and a number of experimental studies ...

Development and Verification of Triple-Ridge-Shaped Cutter for PDC Bits
SPE Journal, 2022Summary Polycrystalline diamond compact (PDC) cutter is the key component of PDC bits, whose rock-breaking characteristics are particularly crucial for the bit performance. Based on the understanding on rock-breaking characteristics of various shaped cutters, the multiridge-shaped cutter has been developed to improve the cutting ...
