When specified (see 6.2), one complete shaper shall be subjected to first article inspection (see 6.4) in accordance with 4.4. 3.2 Design. The shaper shall be new (not a prototype) and one of the manufac
21、turers current production models capable of operations in accordance with the requirements herein. The shaper shall include all components, parts, and features necessary to meet the performance requirements specified herein. All parts subject to wear, breakage, or distortion shall be readily accessi
22、ble for adjustment, replacement, or repair. 3.2.1 Measurinq and indicatinq device calibrations. Measuring and indicating devices shall be graduated in inch-pound (see 6.5.1), metric (see 6.5.2), or dual (inch-pound and metric) units as specified by the procuring activity (see 6.2). Regardless of the
23、 measurement system used, all measuring and indicating devices on the shapers shall be graduated in the same system. 3.2.1.1 Dials. All dials used to indicate machine axes position or tool movement shall be graduated in increments not larger than 0.001 inch. Dial and handwheel circumferences shall b
24、e permanently and legibly engraved or etched on a nonglare background with graduations that can be read from the operators normal position. All feed dials shall have independent zero adjustments and shall be calibrated in such a manner that the last dial graduation progresses into and is continuous
25、with the first dial graduation as the dial is rotated through the zero position. 3.2.2 Reclaimed materials. The machine may contain reclaimed materials to the maximum extent possible provided such materials will not jeopardize the intended use, performance, or design life of the machine. Reclaimed m
26、aterials shall have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of the above shall be interpreted to mean that the use of used, rebuilt, or remanufactured end products are allowed under this specification.
27、 3.2.3 Enerqy efficiency. The shapers and their components that directly consume energy in normal operation shall be designed and constructed for 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-T MIL-S-3788G 32 m 9999906 0469080 b m MIL-S-3788G ene

30、 specified (see 6.2). Covers, guards, or other safety devices normally furnished as standard on the manufacturers commercial shapers suppl ied to the commercial market shall be provided for the point of operation and all other parts of the shapers that present safety hazards. If point-of-operation g
31、uarding is influenced by workpiece size and configuration, the procuring activity shall provide part design data to the supplier of the machine (see 6.2). The supplier of the machine shall provide the special guarding which shall meet OSHA 29 CFR 1910. 3.2.6 Mercurv restriction. The shapers shall no
32、t contain mercury or mercury compounds nor be exposed to free mercury during manufacture. 3.2.7 Asbestos restriction. Asbestos and materials containing asbestos shall not be used on or in the shapers. 3.2.8 Environmental Drotecti on. During the manufacture, operati on , service, transportation, or s

The shapers shall be constructed of parts which are new, without defects, and free of repairs. The structure shall withstand all forces encountered during
38、operation of the shqper to its maximum rating and capacity without permanent distortion or failure. 3.3.1 Castinss and forsinss. All castings and forgings shall be free of defects, scale, and mismatching. No processes such as welding, peening, plugging, or filling with solder or paste shall be used
39、for reclaiming any defective part. Such processes may be used only for enhancing surface finish and appearance. 3.3.2 Fasteninq devices. All screws, pins, bolts, and similar parts shall be installed in such a manner as to prevent unintentional change of tightness. Those subject to removal or adjust
40、shall not be swaged, peened, welded, staked, or otherwise permanently deformed. 3.3.3 Surfaces. All surfaces shall be clean and free of harmful or extraneous materials.
