AISI Rolls Out New Online Bar Steel Machinability Estimator
Detroit, MI, April 9, 2008 – The
American Iron and Steel Institute (AISI) today introduced the new Bar
Steel Machinability Estimator, a tool for automotive engineers to
complete calculations on the machining productivity of carbon and alloy
steels in carbide tooling applications. The machining
productivities of different steel grades can be compared and used in
designing parts to lower overall manufacturing costs.
The new Machinability Estimator is an online tool developed from 10
years of automotive steel data using the most up-to-date machining
methodology, steels and technology. Design, materials and manufacturing
engineers can estimate the machining productivity of carbon and alloy
steels prior to production for the maximum manufacturing impact.
“Machining costs are 20 to 70 percent of the overall value of
automotive parts,” said David Anderson, director, Long Products
Market Development Group. “The Bar Steel Machinability Estimator
offers OEMs and suppliers the ability to select optimal process
parameters which can assist in designing cost-effective parts."
Users can input a steel composition and receive a relative
machinability number or an estimated cutting speed for 30 minutes of
tool life in surface feet per minute. To access the Machinability
Estimator, click here.
The Machinability Estimator builds on the Bar Steel Machinability
Database which is a detailed record of automotive bar steel
machinability under single point carbide turning conditions. It
was developed from several years of controlled testing at eight
different steel and automotive companies. Machinability tests were
conducted on more than 30 significant industrial carbon, alloy,
resulfurized and microalloyed steel grades using carbide tolls in a
standardized single point turning test. To access the
Machinability Database, click here.
”The Machinability Estimator is the most progressive online
resource available for machining productivity,” said Roger Joseph,
project manager, Machinability Estimator and Machinability Database.
“This online resource moves technology and information forward for
today’s automotive industry. Tests are currently underway
using coated carbide tools, and those test results will be incorporated
into the Machinability Estimator upon completion.”
Through the support of the American Iron and Steel Institute, the
Long Products Market Development Group is growing the market for
value-added steel bar and rod products. With seven member companies and
two task forces--Automotive/Heavy Equipment and
Construction/Infrastructure--the group is committed to developing
innovative solutions to the challenges facing their clients and the
steel industry.
