Nothing seems so obvious in subtractive machining than that milling and turning processes really are very different: single point vs. multipoint tools; rotating workpiece vs. rotating tool; static tool vs. rotating tool, etc.

In an automobile engine, seven types of screws out of approximately 70 are considered critical to achieving the engine’s specified design performance, despite high vibration and heat. The seven include bolts for the cylinder head, crankshaft, con rod, flywheel, and main bearing cap, as well as for the camshaft cap, camshaft sprocket and VCT.

A new breed of turbochargers constructed of super tough alloys operates at higher temperatures and rotational speeds than ever before, resulting in greatly increased output in a smaller package for gas and diesel engines alike.

On Thursday, November 3, 2016, Greenleaf Corporation officially launched the revolutionary ceramic insert grade XSYTIN-1 with a press event at their global headquarters in Saegertown, PA.

YG-1, Vernon Hills, Illinois, has added SV-Point spade drill inserts to its product line. The inserts provide longer tool life at higher spindle speeds and feeds than conventional spade drills, according to the company.

Carbon fiber reinforced polymer (CFRP) composite materials deliver the important performance advantages of high strength-to-weight ratio, durability, and extreme corrosion resistance in lightweight structures, valued especially for demanding aerospace and oil and gas industry applications.

Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.

Tool life, geometry, and stability largely depend on proper edge preparation. Tool Flo, located in Houston, Texas, is a manufacturer of carbide cutting tools such as inserts for threading, turning, and milling. The company uses Alicona’s optical 3D measurement systems in the quality assurance of inserts.

In conventional metal (material) removal processes like milling, turning, drilling, boring, and grinding, the challenge is always to hold the tool securely and rigidly against a fixtured workpiece without interfering with the process.
