This Part of BS 4185 describes a method for the determination of the pilot diameter, d,<\/i> of a 60\u00b0 centre hole, type A, B or R as illustrated in Appendices A to C of BS 328-2:1972, covering the range 0.5 mm \u2a7d d<\/i> \u2a7d 50 mm.<\/p>\n

This method applies only to workpieces satisfying the following conditions:<\/p>\n

    \n
  1. force acting at the centre hole, F<\/i>G<\/sub>, \u2a7d 180 000 N;<\/li>\n
  2. cutting force, F<\/i>s<\/sub>, \u2a7d 110 000 N;<\/li>\n
  3. where \u2a7e 3 or \u2a7e 6.3<\/b> (see BS 328-1 for D<\/i> in relation to d<\/i>) (see also clause 2<\/b>).<\/li>\n<\/ol>\n
    \n

    NOTE 1 The theoretical concept is explained in Appendix A and additional considerations are given in Appendix B.<\/p>\n

    NOTE 2 A typical centre hole is illustrated in Figure 1.<\/p>\n

    NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.<\/p>\n<\/blockquote>\n
