Recordkeeping
and traceability are vital to companies operating in the oil and gas
equipment manufacturing sector. As part of a company-wide quality
protocol, FMC Technologies in Dunfermline, Scotland continually invests
in a preventive maintenance program that uses Renishaw machine tool
probes and calibration products to check and verify the dimensional
accuracy of its CNC machine tools. The resulting data are stored for
quick retrieval and easy access using Renishaw’s CNC Reporter software.
FMC
Technologies is a Houston, Texas-based developer and manufacturer of
oil and gas Production Control Systems (PCS), which consist of topside
controls, power equipment, a subsea control module, various sensors, and
subsea electrical and hydraulic distribution equipment. The entire
system is configurable according to conditions and requirements, and
provides engineers aboard oil or gas production platforms with precise
control of the well.
FMC Technologies has
operations around the world near the major oil and gas industry
epicenters. The company's UK manufacturing operation is in Dunfermline,
Scotland, near Edinburgh, where Craig Simpson and Mike West are FMC
Technologies maintenance technicians with responsibility for the service
and support of 20 CNC machine tools of various types, makes and ages.
Also in their charge is one of the company's more recent investments: a
$4 million, purpose-designed and built, SCM machining cell consisting of
two Okuma Space Center MA-600HB CNC horizontal boring machines, loaded
and managed by a Fastems automation system.
To
help speed machine checking and calibration in the SCM cell, FMC
Technologies has designed and built a custom calibration block, which it
mounts on the Okuma machines during scheduled maintenance or when the
machine is being checked.
"We're currently
introducing a new pallet size in the SCM cell and some of the
re-programming is being done manually, rather than off-line, using the
Siemens NX CAE system. And, there’s increased potential for minor
collisions,"said Simpson. "For example, we recently had a small knock,
so first we ran the ballbar to confirm the three axes were square. We
also checked the Y-axis using a test bar and compared the results to the
data in CNC Reporter. We found that the zero position had been
affected, so we re-taught the machine new zero positions using the test
block."
