20、, Switzerland and United Kingdom. BS EN 12417:2001+A2:2009 EN 12417:2001+A2:2009 (E) 4 Introduction This European Standard is a type C standard as stated in EN 2921. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this typ
21、e C standard take precedence. Machining centres present a wide range of hazards, not least from their wide application as rotating tool, stationary workpiece machine tools, for general purpose cutting of cold metal work material. Protection of operators and other persons from contact with moving cut
22、ting tools, especially when being rapidly rotated in the spindle, or being swung from a tool magazine to the spindle during power-operated tool changing, or from contact with fastmoving workpieces, is of great importance. When poweroperated mechanisms are provided for workpiece transfer, they can al
23、so create hazardous situations during loading/unloading and workpiece alignment or clamping. Total enclosure of the work zone using guards during cutting is practicable for smaller machines. The requirements for access to the work zone of large machines used for the processing of a wide range of wor
24、kpiece configurations can require that operators are safeguarded by other means (e.g. perimeter fencing, protective devices at the operating position). Pendant controls enable operators to move around the machine, especially large machines, and to view the work zone, the load/aligning, clamping, cut
25、ting, or unloading operations, maneuvering the pendant control as they move. The significant hazards covered by this standard are those listed in clause 4. The safety requirements and/or protective measures to prevent or minimize those hazards identified in Table 1 and procedures for verification of
26、 these requirements or measures are found in clause 5. The figures in annex C are examples only and are not intended to illustrate the only interpretation of the text. N 12417:2001+A2:2009BS E EN 12417:2001+A2:2009 (E) 5 1 Scope 1.1 This standard specifies the technical safety requirements and prote
27、ctive measures to be adopted by persons undertaking the design, construction and supply (including installation and dismantling, with arrangements for transport and maintenance) of machining centres (see 3.1). 1.2 This standard takes account of intended use including reasonably foreseeable misuse, m
28、aintenance, cleaning, and setting operations. It presumes access to the machine from all directions. It describes means to reduce risks to operators and other exposed persons. 1.3 This standard also applies to the workpiece transfer devices when they form an integral part of the machine. 1.4 This st
29、andard deals with significant hazards relevant to machining centres when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). 1.5 Hazards arising from other metal working processes (e.g. grinding, turning, forming, EDM, laser processing) are covered by othe
30、r standards (see Bibliography). 1.6 This standard applies to machines which are manufactured after (its date of publication). 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the app
31、ropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
