![]() Now I had a permanent place on the table to set my Hamer (I got sick of having something bolted to the table so it went away). I then decked that off using the facemill. I'm not sure if this is hysteresis in the system, or expansion of the spindle under rotational forces.Īnother way I used to do it was set my facemill using the above gage, then bolt a piece if aluminum to the table that was slightly taller than my gage. I say reasonably precise, because it usually gives me an error of. ![]() This gives me a reasonably precise indication of my Z position of the part in reference to the top of the gage. When I probe a Z position with the Hamer, I bring it down until it just registers at. I can then set that position as my "tool height offset" for the Hamer. When I use my Hamer in conjunction with this system, I simply bring the probe down onto the gage until the dial on the gage reads zero (just like setting a tool offset), because the spring in the Hamer is much stiffer than the spring on the gage, it doesn't move at all. The distance from that base Z Zero to the top of the part is entered into the control as my Z offset. The top of the above gage while sitting on the table is my base Z Zero for all of my tools. I use an Edge Dial indicator height gage for setting my tool length offsets: I don't have a Renishaw Touch Probe on the machines I currently have, so take this as another example of a way to use the 3D Taster. ![]()
