Cutter for a pavement router

Abstract

A cutter for use with a pavement router, the pavement router having a pair of cutter supports, the cutter supports being spaced apart a known distance, the cutter includes a plurality of blades disposed radially about a hub, the hub being operably coupled to each of the plurality of blades and having an arbor defined therein along a longitudinal axis, the hub having a certain width dimension taken along the longitudinal dimension, the width dimension being just slightly less than the known distance that the cutter supports are spaced apart so that the hub extends substantially from cutter support to cutter support when disposed between the pair of cutter supports. A method of forming a cutter for use with a pavement router is further included.

1 . A cutter for use with a pavement router, the pavement router having a pair of cutter supports, the cutter supports being spaced apart a known distance, the cutter comprising: 
 a plurality of blades disposed radially about a hub; and    the hub operably coupled to each of the plurality of blades and having an arbor defined therein along a longitudinal axis, the hub having a certain width dimension taken along the longitudinal dimension, the width dimension being substantially coextensive with the known distance that the cutter supports are spaced apart so that the hub extends substantially from cutter support to cutter support when disposed between the pair of cutter supports.    
   
   
       2 . The cutter of  claim 1 , the arbor being operably rotatably couplable to a supporting cutter pin, arbor having an inside diameter that is slightly greater than an outside diameter of the cutter pin.  
   
   
       3 . The cutter of  claim 2 , the arbor having an inside diameter that is less than 1.778 mm (0.070 inches) greater than the outside diameter of the cutter pin.  
   
   
       4 . The cutter of  claim 2 , the arbor having an inside diameter that is between 1.778 mm (0.070 inches) and 0.00254 mm (0.001 inches) greater than the outside diameter of the cutter pin.  
   
   
       5 . The cutter of  claim 1 , the hub width dimension being between 38.1 mm (1.50 inches) and 76.2 mm (3.0 inches).  
   
   
       6 . The cutter of  claim 1 , the hub width dimension being about 55.88 mm (2.200 inches).  
   
   
       7 . A cutter for use with a pavement router, the pavement router having a pair of cutter supports, the cutter supports being spaced apart a known distance, the cutter comprising: 
 a plurality of blades disposed radially about a hub; and    the hub being operably coupled to each of the plurality of blades and having an arbor defined therein along a longitudinal axis, the hub having a certain width dimension that is substantially co-extensive with an exposed portion of a cutter pin when the cutter pin is supported between the cutter supports.    
   
   
       8 . The cutter of  claim 7 , the arbor being operably rotatably couplable to the supporting cutter pin, arbor having an inside diameter that is slightly greater than an outside diameter of the cutter pin.  
   
   
       9 . The cutter of  claim 8 , the arbor having an inside diameter that is less than 1.778 mm (0.070 inches) greater than the outside diameter of the cutter pin.  
   
   
       10 . The cutter of  claim 9 , the arbor having an inside diameter that is between 0.254mm (0.070 inches) and 0.00254 mm (0.001 inches) greater than the outside diameter of the cutter pin.  
   
   
       11 . The cutter of  claim 7 , the hub width dimension being between 38.1 mm (1.50 inches) and 76.2 mm (3.0 inches).  
   
   
       12 . The cutter of  claim 7 , the hub width dimension being about 55.88 mm (2.200 inches).  
   
   
       13 . A method of forming a cutter for use with a pavement router, the pavement router having a pair of cutter supports, the cutter supports being spaced apart a known distance, the cutter comprising: 
 disposing a plurality of blades radially about a hub; and    operably coupling the hub to each of the plurality of blades and defining an arbor therein along a longitudinal axis, the hub having a certain width dimension taken along the longitudinal dimension, forming the width dimension just slightly less than the known distance that the cutter supports are spaced apart so that the hub extends substantially from cutter support to cutter support when disposed between the pair of cutter supports.    
   
   
       14 . The method of  claim 13 , the arbor being operably rotatably couplable to a supporting cutter pin, arbor having an inside diameter that is slightly greater than an outside diameter of the cutter pin.  
   
   
       15 . The method of  claim 14 , the arbor having an inside diameter that is less than 0.254 mm (0.010 inches) greater than the outside diameter of the cutter pin.  
   
   
       16 . The method of  claim 14 , the arbor having an inside diameter that is between 1.778 mm (0.070 inches) and 0.00254mm (0.001 inches) greater than the outside diameter of the cutter pin.  
   
   
       17 . The method of  claim 13 , the hub width dimension being between 38.1 mm (1.50 inches) and 76.2 mm (3.0 inches).  
   
   
       18 . The method of  claim 13 , the hub width dimension being about 55.88 mm (2.200 inches).
