9、ard (This forward is not part of American National Standard O1.1-4 (2015).) Historical Perspective The revision of the original Safety Code for Woodworking Machinery was approved in 1944. The Standards Committee was reorganized in 1952, and the scope of the standard was changed. A comprehensive revi

10、sion of the section on cooperage machinery was completed and a new section dealing with radial-type saws was included. The resulting standard was issued in 1954 and reaffirmed in 1961. In 1969 the Standards Committee was again called and revised the 1954 (R1961) standard. The 1971 revision corrected

11、 and clarified several issues related to guarding and incorporated as a section of the standard an important head note in Section 6.1 of earlier versions of this standard. The standard was again revised and issued in 1975. In 1979 an amendment was made to the 1975 edition. Subsequent updates were pu

12、blished in 1992, 2002, 2004, 2009 and 2013. Prior to the 2004 edition, the committee adopted a resolution regarding the US Occupational Safety and Health Administration (OSHA). The resolution remains in agreement with this edition and is therefore reproduced here: Resolved: As the standards develope

13、d by this committee are relevant to the health and safety of workers in the wood working industry, and as this committee is charged with developing such standards and recognized for its expertise in wood working industry safety and machinery, it is the intent and expectation of this committee that n

14、ewly published versions of standards developed by this committee be adopted by the US Department of Labor as regulations under the United States Occupational Safety and Health Act. The 2004 edition marked the beginning of a new process for the standard. Hereafter, the O1.1 standard will remain relat

15、ively static and new standards will be developed for specific machine within the scope of the O1.1 standard. Thus the O1.1 standard is considered an “umbrella” under which subsequent standards are developed. As a continuation of that process, the draft of the first edition of ANSI O1.1-4, Safety Req

16、uirements for Shapers was first published in 2015. Suggestions for improvement of this standard are welcome. They should be sent to the Wood Machinery Manufacturers of America, 9 Newport Drive, Suite 200, Forest Hill, MD 21050; jenniferwmma.org. AMERICAN NATIONAL STANDARDS ANSI O1.1-4 (2015) v This

20、 effective one year following the date of its publication, and apply to machines manufactured or re-manufactured after that date. 1.4 Machines Excluded AMERICAN NATIONAL STANDARDS ANSI O1.1-4 (2015) 2 Routers, Computer Numerical Controlled (CNC) Machines, machines equipped with outboard bearings; ma

21、chines equipped with powered movements of front extension table and/or tenoning sliding table; hand held woodworking machines or any adaptation permitting their use in a different mode, i.e. bench mounting. E1.4 See ANSI O1.1 for description of routers. 2. Definitions The definition of a term in thi

22、s standard is for the purpose of the standard and is not to be construed as universal in its application. E2. For additional applicable definitions, refer to ANSI O1.1. 2.1 Shaper: A machine that uses one or more fixed or tiltable vertical spindle(s), rotating cylindrical cutter(s) and a horizontal

23、table. The spindle(s) passes up through the plane of the table and its drive motor is located beneath the table. The machine may have any of the following features: a) the ability for the spindle to be raised and lowered through the table b) the ability to tilt the spindle E 2.1 A machine of this ty

24、pe may be a single or multiple spindle type. Some shapers have spindle(s) that can be adjusted to different angles to the table top. Some have sliding tables for straight line shaping. Internationally, shapers may be referred to as toupies (single spindle vertical moulding machines). 2.2 Straight Li

25、ne Profile Shaper: Incorporates a movable table that transports the workpiece in a straight line direction, and movable mounted spindle(s) that travel perpendicularly to the moving table in order to follow the profile of a template while shaping the workpiece edge. 2.3 Climb Cutting: Climb cutting i

26、s a cut where the workpiece is fed in the same direction as the rotation of the cutting tool. E2.3 Climb cutting is hazardous. The cutting tool can catch the workpiece and pull the operators hands into the rotating tool. The operator cannot hold the workpiece tightly enough to AMERICAN NATIONAL STAN

27、DARDS ANSI O1.1-4 (2015) 3 overcome this force. This operation should only be performed in conjunction with a power feeder. 2.4 Curved Shaping: Machining of a curve on a work-piece by having one side in contact with the table (or if held in a jig with the jig in contact with the table) and the other

28、 in contact with the vertical reference of a steady or arbor collar when using a jig. 2.5 Fixture/Jig: A device to locate, hold, and or clamp one or more work pieces in the desired position so operations can be performed and keep the operators hands a safe distance from the cutting tool. E 2.5 Fixtu

29、res/Jig: The design of devices of this type is typically dependent upon the design of the workpiece or operation being processed. 2.6 Freehand: Operation where the operator hand-feeds a workpiece against the cutting tool to complete an operation without the use of a guide, locating device, or power

30、feeder and where the machining of the workpiece is entirely dependent on the skill of the operator. 2.7 Lead in device: A device that provides a fulcrum to guide and steady the workpiece during the start of the cut. E2.7 Starting pins or fixtures can be types of lead in device(s). 2.8 Manual Shaping

31、. Any shaping operation on a stationary spindle shaper where the workpiece is hand-fed and controlled by the operator. 2.9 Slip Knives: A cutting tool with a profile on one edge E 2.9 Slip knives are sometimes known as “Open Knife Tooling” AMERICAN NATIONAL STANDARDS ANSI O1.1-4 (2015) 4 that is mou

32、nted between two platens and is held in place by the clamping pressure of the two platens. 2.10 Stopped Work: A straight cut where the cut extends over part of the length of the workpiece. The cutters have to break into or out of the solid face of the workpiece instead of starting at the end of the

33、workpiece. E. 2.10 May also be known as Plunge Cuts, Blind Cut, or interrupted cuts. 2.11 Tool holder. A device that holds the tool and transmits the rotation of the spindle to the tool. It may or may not be integral to the spindle. 3. References 3.1 Normative References: Applicable portions of the

The main operating controls for starting, normal stopping, emergency stopping, spindle adjustment, and direction of rotation shall be located in an area where they are accessible to the operator in their normal operating posi

42、tion. 5.1.2 Normal Stop. A stop control shall be used which stops all machine actions. 5.1.3 Emergency Stop.

44、e marked on the machine and easily visible from the area where the speed is changed. E 5.3 Operating Speeds: Some tools may not be suitable for all the possible spindle speeds of the machine. The operator/setup person must know the speed the machine spindle will rotate so that cutting tools can be m

45、atched to the operating speed. 5.4 Cutting tool diameter. The manufacturer shall specify the maximum permissible cutting tool diameter. 5.5 Tool Coasting Hazards: Where normal use exposes the operator to the potential for injury due to a revolving or moving tool after the power has been de-energized

46、; means shall be provided to stop the revolving tool as fast as reasonably possible without creating additional hazards, but in no case longer than 10 seconds. . E5.5 Tool Coasting Hazard: Means to satisfy this requirement include braking devices, or coasting time less than 10 seconds. The coasting

47、time will vary with the size of the tool on the spindle 5.6 Vibration: The equipment shall not vibrate excessively when operated, and shall not be operated if vibration exceeds manufacture specifications. E5.6 Excessive vibration can compromise structural integrity of the equipment and produce machi

48、ne failures. In addition, vibration can cause adverse physiological effects. The equipment user should consult applicable standards and regulations regarding allowable exposures for whole body and hand-arm vibration. 5.7 Table Opening: 5.7.1 The opening in the table shall be AMERICAN NATIONAL STANDA
