But considering the tool offset, which is the radius of the end mill, after raising the end mill above the part we can move in the x-direction towards the part by a distance equal to the radius, then zero the X-axis by pressing X and absolute set, you will need to repeat this entire process to zero the Y-axis. For zeroing the X-axis, turn on the milling machine and slowly move the end mill into the direction of the X-axis towards the part, and stop when you see a small puff of metal shavings, and zero the X-axis by pressing X. You do not need to remove and insert a drill chuck with the pointer, after the end mill is lowered and ready to cut your part. This technique is faster than the first one. Touch the stock slightly with an end mill

Scribe two lines on your stock on where you want your origin to be, then move your pointer over the intersection on what you think is close enough, finally to zero the X and Y axis (press X and Y).Ģ. The first method of CNC milling part zeroing is better to use when you have ample material. There are three ways to set an origin on the part in CNC. Use some other parallels to properly raise your stock up from the vise for through holes. Use a hammer to hit the stock and the handle, repeat as necessary to ensure the stock and the parallels underneath can’t move, parallels are also up against the vise. Choose a type of metal (steel, aluminum, or others) as the stock and tighten it in the vise.
