A new approach for controlling of curved cutting edges of toroid-shaped end-milling cutter

Defense + Commercial Sensing, 2021
Toroidal end mills have great industrial applications and have good prospects for increasing the volume of products produced with them. It complicates the process of measuring the cutting edges by changing the position of the cutting edges along the axis,

Study on rock-breaking mechanism of axe-shaped PDC cutter

Journal of Petroleum Science and Engineering, 2021
Abstract Polycrystalline diamond compact (PDC) cutter is the key component of a drill bit. Recently the shaped PDC cutters, especially the axe-shaped cutter (ASC), have been warmly welcomed by the drilling engineers. However, the rock-breaking mechanism of ASC is rarely studied.

CNC Cutter Path Generation in Shape Deposition Manufacturing

Concurrent Product and Process Engineering, 1995
Abstract Shape Deposition Manufacturing is a layered manufacturing process which attempts to build functional parts by incremental material deposition and fusion of three-dimensional layers. Five-axis CNC machining is employed in Shape Deposition Manufacturing to machine the layers to the net shape.

Enhancing Casing Drill Out Consistency and Unconventional Interbedded Drilling Efficiency with in-Bit Data Capture and Shaped Cutter Technology

International Petroleum Technology Conference
Drilling out casing equipment with a Polycrystalline Diamond Compact (PDC) bit is a challenge, as it can result in prematurely Pulling Out of Hole (POOH) while drilling formation due to bit damage.
