Description / Abstract:
GENERAL
This Standard establishes methodology for specifying and testing the
performance of CNC machining
centers. In addition to clarifying the performance evaluation, this
Standard facilitates
performance comparisons between machines by unifying terminology,
general machine classification,
and the treatment of environmental effects. It provides a series of
tests that should be used to
perform acceptance testing (runoff) of new and reconditioned machines
and could be used to verify
continued capability of production machines, already in operation,
through periodic testing. The
set of acceptance tests and the specification limits for machine
conformance shall be the subject
of contractual agreement between the Supplier and the User. This
Standard is rather comprehensive;
therefore, for smaller and less expensive machines the conformance to
specifications could be based
on a recommended subset of tests to evaluate machine performance.
PERFORMANCE FORMS
Any performance forms described, as complying with this Standard,
shall include at least those
items specified in Forms 1.1 through 1.6. Other forms shall be
included, depending on the
acceptance tests agreed between the Supplier and the User. The form
for machining test parts is
included in Chapter 8 as Form 8.1.
