Semicircle in the processing center how to do the program
And then give the R value of the milling circle, also the distance from the center to the starting point, the program is G2 (or G3) i .. (or J .. round gauge open distance) X..Y .. (pen end position)
Machine circle is the first move to the starting point (the starting point of the pen) G1 x..y ..
Principles and compasses round almost, the bow opening (circle radius), the needle inserted in the center, the pen from the starting point to the end, get.
Need three coordinates, namely: the center of the circle, arc starting point, the end of the arc three.
