66 -- ROTATING TOOL DYNAMOMETER SOL Q660052 POC Diane Loeb (301) 975-6399, Sharon Farinholt (301) 975-6339 The National Institute of Standards & Technology (NIST) intends to procure a state-of-the-art piezo-electric dynamometer system under Simplified Acquisition Procedures, for the Automated Production Technology Division's, Manufacturing Engineering Laboratory. The rotating force dynamometer shall be used in measuring cutting forces in moderate to high speed milling applications. The dynamometer shall be capable of measuring three orthogonal cutting force components and cutting torque about the axis of rotation of the cutting tool. The device shall be able to measure these quantities at cutter rotation rates of up to 10,000 revolutions per minute. The maximum amplitude of the cutting force measurements shall be 20-30 kN and the maximum amplitude of the torque measurements shall be at least 1500 N-m. The bandwidth of the measurements shall be greater than or equal to 1000 Hz with at least 12 bit resolution. The dynamometer shall be able to interface with a data acquisition board on a personal computer. The mechanical characteristics of the dynamometer shall be sufficient to limit vibrations occuring during cutting. Delivery is FOB Gaithersburg, MD within 10 weeks after award. Offerors shall provide technical literature of the offered rotating dynamometer; references of past performance. To obtain a quotation package by facsimile, call Diane Loeb at (301) 975-6399 or submit request by facsimile (301) 963-7732. Quotations are due no later than 3:00 p.m. local time on May 23, 1996. The Government anticipates award of a firm-fixed price purchase order to the lowest priced technically acceptable offer conforming to the specifications. THIS IS A SMALL BUSINESS SET ASIDE under SIC Code 3829. See Numbered Notes 1 and 12. All responsible sources may submit a quotation which shall be considered by the agency. FAX Number (301) 963-7732.
