    1、 for Machine Tools Safety Requirements for Gear and Spline Cutting Machines American National Standards Institute www.ansi.orgANSI B11.11 2001(R07) AMERICAN NATIONAL STANDARDS By approving this American National Standard, the ANSI Board of Standards Review confirms that the requirements for due proc

    2、ess, consensus, balance and openness have been met by AMT The Association For Manufacturing Technology (the ANSI-accredited standards developing organization). American National Standards are developed through a consensus process. Consensus is established when substantial agreement has been reached

    3、by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward resolution. This process brings together volunteers a

While AMT administers the process and establishes procedures to promote fairness in the development of consensus, it does not write the document and it does not independently test, evaluate or verify

    5、the accuracy or completeness of any information or the soundness of any judgments contained in its standards or guidelines. American National Standards are promulgated through ANSI for voluntary use; their existence does not in any respect preclude anyone, whether they have approved the standards or

    6、 not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. However, users, distributors, regulatory bodies, certification agencies and others concerned may apply American National Standards as mandatory requirements in commerce and i

    7、ndustry. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of an American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the Ame

AMT makes no warranty, either expressed or implied as to the fitness of merchantability or accuracy of the information contained within this standard, and disclaims and makes no warranty th

    28、 is to eliminate or control hazards to personnel associated with gear and spline cutting machines by establishing requirements for the construction, operation and maintenance of these machines. To accomplish this objective, responsibilities have been assigned to the supplier (e.g., manufacturer, reb

    29、uilder, modifier, installer, integrator), the user, and personnel in the working environment. The words “safe“ and “safety“ are not absolutes. Safety begins with good design. While the goal of this standard is to eliminate injuries, it is recognized that risk factors cannot be practically reduced to

    30、 zero in any human activity. This standard is not intended to replace good judgment and personal responsibility. Operator skill, attitude, training, job monotony, fatigue and experience are safety factors that must be considered by the user. Manual turning machines and associated equipment technolog

    31、ies are continuously evolving. This standard is reflective of the most commonly used and time-tested state of the art at the time of its approval. The inclusion or omission of language relative to any evolving technology, either in the requirements or explanatory areas of this standard, in no way in

    32、fers acceptance or rejection of such technologies. Inquiries with respect to the application or the substantive requirements of this standard, and suggestions for its improvement, are welcomed and should be sent to the AMT The Association For Manufacturing Technology, 7901 Westpark Drive, McLean, Vi

The term “SHOULD” denotes a recommendation, a practice or condition among several alternatives, or a preferred method or course of action. Similarly,

    38、 the term “CAN” denotes a possibility, ability or capability, whether physical or causal, and the term “MAY” denotes a permissible course of action within the limits of the standard. By convention, the B11 standards do not use the term “and/or” but instead, the term “OR” is used as an inclusive disj

    40、he primary purpose of every machine tool is to process parts. This is accomplished by the machine imparting process energy onto the workpiece. Inadvertent interference with, or accidental misdirection of the released energy during production, maintenance, commissioning and de-commissioning may resul

    41、t in injury. The primary purpose of the ANSI B11 series of machine tool safety standards is to devise and propose ways to minimize risks of the potential hazards. This can be accomplished by an appropriate machine design, by restricting personnel and other individuals access to hazard areas, and by

    42、devising work procedures to minimize personnel exposure to hazardous situations. This is the essence of the ANSI B11 series of safety standards. The responsibility for the alleviation of these risks is divided between the equipment supplier, its user and its operating personnel, as follows (numbers

    43、in parentheses refer to the clause numbers in these standards which address that responsibility): SUPPLIER USER Responsible for: Instruction manual Operation manual Maintenance manual (4.1) Overall workplace safety Maintenance and inspection procedures Training (4.2) Task and hazard identification (

    44、5.1) Risk assessment/risk reduction (5.2) Design and construction (6) Set-up, Operation & Maintenance (9) Safeguarding (8) Layout, installation, testing and start-up (7) PERSONNEL Comply with instructions (4.3) B11.19 NFPA 79 For task/hazard combinations for which the standard does not provide protective measures, apply the principles of B11.TR3
