Machining of Graphite/Epoxy Composite Materials With Polycrystalline Diamond (PCD) Tools
Journal of Engineering Materials and Technology, 1991Machining of graphite/epoxy composite material is investigated by turning (cutoff) tests using different grades of polycrystalline diamond (PCD) inserts. The wear behavior of the PCD cutting edge is characterized by small cracks, rounded edges, and flank wear.

Recent Advances in Polycrystalline Diamond (PCD) Technology Open New Frontiers in Drilling
Proceedings of SPE Annual Technical Conference and Exhibition, 1987Abstract Recent developments in polycrystalline diamond (PCD) technology have led to breakthroughs in PCD bearing designs and PCD insert cutting structures. The authors suggest that the next major step in bit technology will be to combine these two innovations in a new generation roller cone bit, capable of sustained operation with a PDM

Research on manufacturing and application of polycrystalline diamond (PCD) tools
2017Titanium alloys have been wide applied in industry, but they are difficult to machine due to the severe cutting conditions including high temperature at tool/chip interface and highly abrasive interaction at tool/workpiece interface. Polycrystalline diamond (PCD) has been gradually used for machining titanium alloy because of its high hardness and ...

Polycrystalline Diamond (PCD) Tool Material: Emerging Applications, Problems, and Possible Solutions
2014This chapter first discusses the challenges with the tool material selection for machining of high-silicon aluminum-matrix composites. It is shown that the combination of a soft easy-to-adhere Al-matrix and highly abrasive particles limits the use of cemented carbide tools due to high rate of adhesion and abrasion wear. The issue becomes intolerable in

Journal of Materials Processing Technology, 2005
Abstract Wood-based composite materials are used extensively for interior and exterior construction applications. These materials are typically pressed into sheet form and then machined to the required size and profile using cutters such as circular saws, band saws and routers. These cutters are tipped with hard cutting tool segments that perform the

International Journal of Refractory Metals and Hard Materials, 2019
Abstract In the metal working industry, cutting tools for high precision application are usually made from non-conventional super hard materials, for example, diamond (D) and cubic boron nitride (CBN). These materials are composites of geometrically undefined grains embedded in metallic binder.
