A 5-axis and a part manufactured with it.Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by away excess material, by. This type of machining was originally performed mechanically on large complex machines. These machines operated on 4, 5, 6, and even 12 axes which were controlled individually via levers that rested on cam plates. The cam plates offered the ability to control the tooling device, the table in which the part is secured, as well as rotating the tooling or part within the machine. Due to the machines size and complexity it took extensive amounts of time to set them up for production. Once machining was introduced it provided a faster, more efficient method for machining complex parts.Not commonly known, the developer of the first CNC 4-axis mill and first CNC 5-axis mill was Kenny Weld in the late 1980's.
Kenny was a Hall of Fame dirt Sprint Car racer (having won over 200 races) from Missouri. A part of the famous Weld Racing family, Kenny's brother, Greg Weld, owned Weld Racing Wheels which machined light weight racing wheels with traditional CNC controlled 3-axis mills & lathes.
Kenny was arrested on drug charges in 1983 and served 52 months in prison. Having felt he embarrassed his family and the racing community, after his release, Kenny worked in his garage to develop the first 4-axis CNC milling machine. His primary focus was to port automotive racing cylinder heads consistently. Kenny had two primary goals for CNC multi-axis machining. The first was to reward the talented cylinder head porters by replicating their superior port designs in an ongoing basis and be paid royalties. The second goal was to take the human inconsistency out of ported cylinder heads in the racing industry.Kenny's belief (later proven to be accurate) was race engine builders could focus on other areas of engine power development, knowing all of their cylinder heads flowed equally and to the best of their ability. Kenny Weld sold the first CNC 4-axis milling machine (his prototype) to Robert Yates of Robert Yates Racing, a NASCAR race team and engine builder.

This provided Robert Yates Engines and his race teams a significant performance advantage for a number of years, as his engines made more power consistently.The 4-axis machine would only work on automotive cylinder heads where the ports curved up or down, but not left or right. Kenny Weld used the funds from the sale of the 4-axis machine to develop the 5-axis CNC machine, which allows CNC machining into ports that turn any direction. Once finished, Kenny intentionally chose not to patent the 5-axis machine technology. He wanted it to be open source, so the machines could be built and sold inexpensively. Today, 5-axis CNC machining is the standard in many industry manufacturing processes, including automotive OEMs and racing.
Kenny was diagnosed in 1995 with non-Hodgkin's lymphoma and passed away the following year.Typical CNC tools support in 3 axis; multiaxis machines also support rotation around one or multiple axis. 5-axis machines are commonly used in industry in which the workpiece is translated linearly along three axes (typically x, y, and z) and the tooling spindle is capable of rotation about an addition 2 axes.There are now many CAM software systems available to support multiaxis machining including software that can automatically convert 3-axis toolpaths into 5-axis toolpaths. Prior to the advancement of Computer Aided Manufacturing, transferring information from design to production often required extensive manual labor, generating errors and resulting in wasted time and material.There are three main components to multiaxis machines:. The machines physical capabilities i.e.
Torque, spindle speed, axis orientation/operation. The CNC drive system, the components that move the machine.
