4. To include service, parts and labor.

5. Incidental Services

5. Installation of the Dual Axis Fast-Wire Contour Cutter, including labor and necessary accessories and optional equipment, shall be included and scheduled in advance with the Government point of contact (POC). The primary POC is Phil Peterson, 402 CMMXSG/MXDQBE, 478-222-4075. The alternate POC is Don Bell, 402 CMMXSG/MXDQBE, 478-222-4066. Installation shall be performed during normal laboratory business hours (0700-1545, Monday thru Friday excluding federal holidays) unless approved by the Government POC or his/her designated representative and the Administrative Contracting Officer (ACO).

5. Training shall be included in the purchase price and consist of five days of on-site familiarity training after installation and completion of demonstration.

5. The contractor shall provide a demonstration of performance capabilities. Upon completion of installation, indicating and recording instruments shall be verified by impressing various predetermined voltages. The instruments shall be verified through their operating range. The fast-wire cutter and its components shall be prepared for operation according to the manufacturer’s operating instruction manual. The part numbers for white foam parts to be used in the demonstration are: 68A321352-2015, 68A321352-2019, and 68A321352-2126. The part numbers for black foam parts are: 8936651-01 slab 15, 8936651-01 slab 21, and 8936651-01 slab 22. A total of 3 white and 3 black foam parts shall be made (1 per part number) during the demonstration. The part’s dimensions will be entered into the computer via the CAD software. The machine shall be run to produce the parts. Each part can then be inspected for compliance with specifications. Accuracy of cut can be verified to be within ± 0.030”. The ability of the CAD software to read dxf or dwg can be verified and the digitizer/scanner operation shall be verified. All demonstrations shall be conducted at an ambient temperature of 77 °F (±15 °F) with a relative humidity of 55% (±10%). The instruments and sensing elements used to perform the demonstrations specified for the fast-wire cutter and instruments shall have been calibrated with standard instrumentation.
