Selecting the Shape of the Insert in a Lathe Cutter

Russian Engineering Research, 2019
Attention 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.

Rock Customized Shaped Cutters Improve Rock Cutting Efficiency

SPE/IADC International Drilling Conference and Exhibition, 2019
Abstract Failing the rock and removal of failed rock are the two primary actions that control drill bit efficiency. A proper design must address both primary actions while focusing on the major efficiency driver. This has been the basis for development of shaped cutter technology where the geometry of polycrystalline diamond compact (PDC)

Micromilling of NiTi Shape-Memory Alloys with Ball Nose Cutters

Materials and Manufacturing Processes, 2009
Micromilling of NiTi shape-memory alloys (SMA) places high demands on tools and machining processes. NiTi is classified as a difficult-to-cut material due to its special properties. A new approach to machine NiTi with higher process flexibility is the application of ball nose cutters in micromilling processes. The article presents the latest results of

Geometric modeling and grinder design for toroid-cone shaped cutters

The International Journal of Advanced Manufacturing Technology, 2005
This paper presents a set of mathematical models for the design and manufacture of the helical flute and cutting-edge curve of a toroid-cone shaped revolving cutter. The study not only considers the section profile and relative feeding velocities of the grinding wheel used in the NC machining of the cutter, but also addresses the deviation of the ...

THE ROUND SHAPED CUTTERS PROFILE CALCULATION FOR EXTERNAL PROCESSING

Science and Technology of Kazakhstan
In this article, an original method for the graph-analytical profiling of round-shaped form tools for external processing is proposed, distinguished by its ability to systematize and automate calculations. Unlike existing approaches, the new method allows for the calculation of the cutter profile with a frontal surface of circular shapes, using both ...
