  56. 56. Material should be securely clamped or placed on a non-slip mat.
  57. 57. The bearing will follow the profile of the edge of the material.</li></ul>Department of Manufacturing & Operations Engineering<br />
  58. 58. WT4603<br />Bearing guided cutters<br />When viewed from above the feed direction for processing a moulding on the outside of a component will be in an anti-clockwise direction.<br />Care needs to be taken when rolling around the corners or coming to the end of a straight as the router plate may not have as much support from the material underneath.<br />Department of Manufacturing & Operations Engineering<br />
  59. 59. WT4603<br />Feed direction<br />Feed direction is critical to the machining process.<br />The cutter rotation will be in a clockwise direction.<br />To establish the correct feed direction use the right hand rule shown in the photo.<br />Place the thumb of the right hand against the edge to be processed.<br />The back of your hand must be facing upwards.<br />Extend the index finger as shown.<br />This finger will point in the direction that you should feed the router.<br />Department of Manufacturing & Operations Engineering<br />
