E-MAIL: Artistine R. Lethcoe-Reid, A.LETHCOE-REID@larc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA LaRC intends to purchase one each of a Rotating cutting force Dynamometer with the following minimum specifications: I. General Description Rotating cutting force dynamometer to measure cutting forces during milling. The dynamometer will be capable of simultaneously measuring forces in four axes: the X (longitudinal), Y (transverse) and Z (vertical) axes, as well as moments (torques) about the Z axis. The dynamometer will include provisions for mounting to a milling machine and holding end mills, a signal conditioner, all applicable interface cables and signal pickups, and manuals. The system shall be completely integrated. II. Features A. The dynamometer will be based on piezoelectric technology in order to minimize deflection of the unit. B. The dynamometer shall mount to a milling machine using a standard taper and provide two tool holders for end mills (see item C under specifications). C. The dynamometer shall be capable of providing force measurements over the full range of travel of the milling machine, 55 inches longitudinally and 17 inches transversely. D. The signal conditioner shall accept low level signals from the dynamometer and shall provide high level outputs (110 V DC) to interface with a data acquisition system. The signal conditioner will accept remote commands from a computer via an RS-232C interface. The signal conditioner shall have two output ranges; range 1 shall be the full scale output (FSO) of the dynamometer, range 2 shall be 10% of FSO. III. Individual Component Specifications A. Transducer (1) Rotation speed of 0 -- 5000 rpm; (2) Expected forces on X and Y axes 14,000 lbs; (3) Expected forces on Z axis 16,500 lbs; (4) Moment about Z axis 11,100 ft-lbs; (5) Permissible overload 20 %; B. Signal conditioner (1)Number of channels 5; (2)Number of ranges per channel 2; (3)Ratio of Range 1/Range 2 10; (4)Cut-off frequency per channel 1 kHz; (5) Sampling rate per channel 7.8 kHz; (6) Resolution 12 bit; (7) Tolerance 10.025%; (8) Output signal range 110 V; (9) Analog signal output connector BNC for each channel; (10)Power 110V AC/60 Hz; (11)Remote control interface RS-232C; C. Machine-Tool Interface (1) Dynamometer shall mount on milling machine using a number 50 Cat V taper spindle adapter. (2) Dynamometer shall provide Weldon type side lock holder mounts for securing 5/8 inch shank diameter and 1 inch shank diameter end mills. The provisions and clauses in the RFQ are those in effect through FAC 97-19. This procurement is a total small business set-aside. See Note 1. The SIC code and the small business size standard for this procurement are 3827 and 500, respectively. The quoter shall state in their quotation their size status for this procurement. Delivery to LaRC is required within 60 days ARO. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9. Quotations for the items(s) described above are due by COB 08/21/00 and may be mailed Mrs. Artistine Lethcoe Reid, NASA, LaRC MS/126, Hampton, VA 23681 or faxed to (757)864-6131 and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative. Quoters are encouraged to use the Standard Form 1449, Solicitation/Contract/Order for Commercial Items form found at URL: http://procure.arc.nasa.gov/Acq/Forms/Index.html to submit a quotation. Quoters shall provide the information required by FAR 52.212-1. If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled "Buy American Act -- Supplies," the quoter shall so state and shall list the country of origin. The Representations and Certifications required by FAR 52.2l2-3 may be obtained via the internet at URL: http://ec.msfc.nasa.gov/msfc/pub/reps_certs/sats/ FAR 52.212-4 is applicable. Addenda to FAR 52.212-4 are as follows:52.211-17, 52.219-6 and 1852.215-84. FAR 52.212-5 is applicable and the following identified clauses are incorporated by reference. 52.222-3, 52.225-13, 52.233-3, 52.222-21, 52.222-26, 52.222-35, 52.222-36, 52.222-37, 52.225-3, Alternate II and 52.232-34. The FAR may be obtained via the Internet at URL: http://www.arnet.gov/far/ The NFS may be obtained via the Internet at URL: http://www.hq.nasa.gov/office/procurement/regs/nfstoc.htm Award will be based upon overall best value to the Government, with consideration given to the factors of proposed technical merits, price and past performance; other critical requirements (i.e., delivery) if so stated in the RFQ will also be considered. Unless otherwise stated in the solicitation, for selection purposes, technical, price and past performance are essentially equal in importance. It is critical that offerors provide adequate detail to allow evaluation of their offer (see FAR 52.212-1(b).
