The work of developing International Sta
4、ndards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been authorized has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part
5、 in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 447 was developed by Technical Committee ISO/TC 39, Machine tools. The fi

10、:52:28 MDTNo reproduction or networking permitted without license from IHS -,-,- INTERNATIONAL STANDARD IS0 447-1984 (E) Machine tools - Direction of operation of controls 1 Scope and field of application This International Standard establishes rules for the direction of operation of controls whose
11、function is to produce movement of controlled machine tool components in one or other of two opposing directions. Its scope does not include controls for components which rotate continuously in the same direction during the normal functioning of the machine (such as controls for electric motors). 2
12、General rules If, for special reasons, the following rules cannot be applied, then the directions of operation of the control and the corre- sponding directions of movement of the controlled component shall be as shown on the machine indicator plate. 2.1 Lever control The lever shall be so placed th
13、at - for the control of a rectilinear movement, the line join- ing the extreme positions of the handle, on either side of the neutral position, is approximately parallel to the direction of the movement of the controlled component; - for the control of a circular movement, the plane in which the lev
14、er arm rotates is parallel to that of the con- trolled component. In either case, the movement of the lever shall produce a move- ment of the controlled component in the same direction This rule is valid for the control of movements produced manually (figure 11, as well as for starting automatic mov
15、ements (figures 2 and 3). Figure 1 Figure 2 / c3 0 f Figure 3 2.2 Push-button control 2.2.1 Fixed control The line of push buttons shall be placed parallel to the move- ment of the controlled component and the operation of the right-hand button, or the furthest button or the top button, shall produc
16、e a movement to the right, or away, or upwards respectively (for an operator placed in the operating position). 1 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/25/2007 19:52:28 MDTNo r
17、eproduction or networking permitted without license from IHS -,-,- IS0 447-1994(E) This rule is applicable for the control of a component with a rec- tilinear movement (figure 4) as well as for the control of a com- ponent with a circular movement, but considering only, in the latter case, the gener
18、al direction of movement of the peripheral part of the controlled component which is the nearest to the line of push buttons (figure 5). / Figure 4 Figure 8 II- Figure 5 2.2.2 Movable control (for example, pendent control) The terms of paragraph 2.2.1 remain valid but it is necessary to show on a mo
19、vable control, which can rotate more than 180, an outline of the machine in order to prevent ambiguity in the directions of motion. 2.3 Wheel control The clockwise rotation of the wheel (for an operator facing the shaft end on which the wheel is mounted) shall produce, for the controlled component,
20、- a rectilinear movement to the right, or away, or up- wards (for an observer looking in a direction parallel to that of an operator in the operating position, if the wheel axis is vertical, or facing the shaft end of the wheel, if it is horizon- tal); Figure 6 Figure 7 - or a clockwise rotation (fo
21、r an observer facing the spin- dle or the shaft end on which the controlled component is mounted); Figure 9 Figure 10 - or a movement towards the centre (clamping of chucks). 3 Special cases 3.1 If the direction (vertically up or down, horizontally to right or left, horizontally away or towards) of
22、the movement of the controlled component can be varied by a preselector device independent of the control under consideration, the above rules apply to that one of the directions which is most fre- quently used. 3.2 If the same lever is used for starting both the cutting movement and the feed moveme
23、nt of the tool, the above rules apply to the feed movement. 2 Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/25/2007 19:52:28 MDTNo reproduction or networking permitted without license from IHS -,-,-
