Blank Size: (minimum dimensions) 3 x 3 x 1”, provided in tool box
Tool: .750 end mill, 2 flute, high speed steel,
sharp
Coolant: Flood coolant or Cool-Tool
1.
Mount vise and indicate the back jaw parallel to the table within .0005”.
2.
Clamp material in vice with a minimum of .800” above the vise jaws.
3.
Load in the Euclid block program from the ProtoTRAK SMX flash disk, which is Part Number Euclid 2 axis.PT4. It
is found under the PT4 folder followed by the SWI TEST PROGRAMS folder.
4.
Use an edge finder to set Absolute 0 on X and Y. Absolute zero is the front left corner of the block as viewed
from in front of the machine.

Load the .750 end mill and set Z Absolute 0 at the top of the part.
6.
Begin to run the program. Set the spindle to 2000 RPM and follow the instructions on the control for SETTING Z
and CHECKING Z. The part will be machined in the following sequence:
Event #
Description
Depth of Cut
1
Circle pocket – cuts middle circle
-0.250”
2
Circle frame – cuts outer 1.830 diameter circle
-0.250”
3
Circle frame – cuts material from corners remaining on Euclid block -0.250”
4

-0.500”
5-12
Cuts triangle on Euclid block with finish cut
-0.500”
13
Rectangular frame – cuts outer 2.750” rectangle
-0.750”
7.
After the program run, the program will locate to the following position.
X = 1.318
Y = 1.318
8.
Mount a dial indicator in the quill and check the circles.
9.
Check the runout of the sides of the square frame.
10.
Inspect the machined surfaces for smoothness.
