ProtoTRAK RMX Euclid Block Procedure
The test part should be machined at the completion of the installation.
The material for the Euclid block test part is found in the toolbox.
•
Material Specification: Aluminum, 6061-T6 or T4
•
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, Cool-Tool or Kerosene
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. It is found under the C drive, PROTOTRAK folder, and TMC
INSPECTION PROGRAMS folder, click on EUCLID.PT10 to run and follow instructions.
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.
5.
Load the .750 end mill and set Z Absolute 0 at the top of the part, and set Z total length offset in
the tool table.
6.
Begin to run the program. The part will be machined in the following sequence:

7.
After the program runs, the program will locate to the following position.
a.
X = 1.318
b.
Y = 1.318
8.
Mount a dial indicator in the quill and check the circles using figure 2.14 as a reference.
9.
Check the runout of the sides of the square frame.
10.
Inspect the machined surfaces for smoothness.
