Locating Edge Finder can be used to find the edge of the part. While the edge finder is spinning, move the tip close to the edge of the part. When the tip is close, it will rotate concentric to the upper section of the edge finder. Once the tip makes contact, the tip will shift sideways, as seen in the picture.

Take the mill out of gear and touch the indicator to the edge of the circle. Manually rotate the spindle.

Locating  

Edge  Finder    -­  can  be  used  to  find  the  edge  of  the  part.  While  the  edge  finder  is  spinning,  move  

the  tip  close  to  the  edge  of  the  part.  When  the  tip  

is  close,  it  will  rotate  concentric  to  the  upper  

section  of  the  edge  finder.  Once  the  tip  makes  

contact,  the  tip  will  shift  sideways,  as  seen  in  the  

picture.  Compensate  for  the  radius  of  the  edge  

finder,  which  is  usually  0.1”.

Dial  Indicator    -­  used  to  find  the  center  of  larger  circles  (typically  larger  than  half  an  inch).  Take  

the  mill  out  of  gear  and  touch  the  indicator  to  the  

edge  of  the  circle.  Manually  rotate  the  spindle.  

Adjust  the  x  and  y  until  the  reading  stays  

constant  as  you  spin  the  indicator.

Part  Stop    -­  can  be  used  when  making  multiple  parts.  The  stop  allows  you  to  change  out  parts  

while  maintaining  your  zero.

A  piece  of  paper  can  be  used  to  find  the  z  zero.  Put  a  piece  of  paper  between  the  tool  and  the  part.  Slowly  lower  the  tool  while  moving  the  piece  of  paper  back  and  forth  until  the  piece  of  paper  cannot  move.  Measure  the  paper  thickness  to  know  how  far  above  the  part  you  are.  

 

Gauge  pins    -­  can  be  used  to  find  the  location  of  small  holes.  Find  the  largest  gauge  pin  that  fits  in  the  hole.  Clamp  the  gauge  pin  into  the  drill  vice.  Eyeball  the  center  of  the  hole.  Gently  try  to  fit  the  gauge  pin  into  the  hole  by  moving  the  quill.  Adjust  the  x  y  until  the  pin  slides  into  the  hole.  This  is  the  center.
