Two things everyone knows about diamonds: they’re very hard and they’re very expensive. And so it is with polycrystalline diamond (PCD) as well as cubic boron nitride (CBN) cutting tools.

Machine shops use a variety of techniques to track the condition of their cutting tools, ranging from simple to sophisticated. No matter what monitoring method is used, it can be crucial in preventing catastrophic tool failure. At its best, monitoring also significantly boosts tool life and slashes tooling costs.

Automated feature recognition, knowledge-based machining, advanced toolpath simulation and digital twins are a few CAM technologies making programming more of a technical exercise than the tribal knowledge-inspired art form it has long been.

Manufacturing Engineering editor-in-chief Alan Rooks is retiring.

Properly balancing one's tools can pay big dividends.

Workholding needs to be super-sized when machining workpieces like truck transmission housings, wind turbine blades, rocket bodies, and more, for industries like aerospace and defense, agricultural, energy, marine, rail, and on- and off-road transportation.

Here’s how leading cutting tool manufacturers describe the pros and cons of standard vs. custom cutting tools.

Metal diffusion bonding is an essential joining method for achieving a high-purity interface when two similar metals require superior structural integrity. The process involves applying high temperature, and pressure to metals mated together in a hot press causes the atoms on solid metallic surfaces to intersperse and bond.

With the use of composites in demanding applications increasing, improving knowledge of their fire performance is becoming a safety-critical issue, particularly for building and transportation applications.

Reverse engineering is becoming multifaceted and complex. The key drivers: new metrology sensors and more capable software, enabled by ever more powerful and cheaper computing.
