Milling software

  1. I uploaded my model from file >> open ,we made sure that the orientation is correct and the dimensions too

  3. After that we chose the type of milling

  4. click on create toolpath ,then edit it and set the material to mill so that the software would generate the feeds ,speeds settings. Moreover, I chose the milling bit

  5. for roughing and finishing we will use the same milling bit which is 1/32 ball nose

  6. To make sure that the milling in the edges will happen I added a slope of 30 degree

  7. For the finishing I used the same milling bit 1/32 ball nose

  8. Then to preview the final result I clicked on show model this will indicate if I will have to adjust or change the milling bits

  9. I zeroed the x,y axis to the middle of the wax and z on the top of the wax

  10. Finally I clicked on start cutting


  1. I draw a X to find the center of the wax
