Lead Angle: Don’t be scared to take five

Although I imagine that some workaholics find taking short breaks frightening, the above headline refers to 5-axis machining, which is one of this issue’s focuses.

In addition to Christopher Tate’s article on page 72 about how investing in a 5-axis machine can pay significant dividends, the Machine Technology column on page 30 is about measuring 5-axis centerlines. The latter is authored by guest columnist Michael Cope, product technical specialist for Indianapolis-based Hurco Cos. Inc.

Coincidentally, Cope just published a book about 5-axis machining titled The Power of Five: The Definitive Guide to 5-Axis Machining, which is available from Lulu Press Inc. (tinyurl.com/y9ganrn3). When considering whether to integrate 5-axis machining, keep in mind that it isn’t only for producing complex parts, such as blisks and impellers for the aerospace industry, via simultaneous 5-axis movements.

In his book, Cope states that the vast majority of work that is driving parts manufacturers to buy 5-axis machines is for five-sided, or 3+2, machining. This positional 5-axis machining enables shops to cut relatively simple geometries on multiple sides of the same part, which can provide a significant competitive advantage by improving part accuracy and throughput. Conversely, a 3-axis approach requires individual, time-consuming setups for each side of the part.

Along with clearly and concisely presented information, Cope’s book is packed with photos and illustrations that complement the copy. The photos do show some of Hurco’s 5-axis machines, but, as was his intention, the information is neutral and nonpromotional.

Another big proponent of 5-axis machining is Titan Gilroy, CEO of the machine shop Titan America MFG, Rocklin, Calif., and executive producer/star of the “Titans of CNC” cable TV show.
