Figure 4.2— Flexdeburr Pointed Teaching Tool
Inside corners represent a complex situation for compliant deburring tools. In general, the bur must not
contact simultaneously both perpendicular surfaces of an inside corner. The resulting force imbalance in two
planes will cause severe tool chatter. The customer should create a tool path that will prevent the bur from
simultaneously contacting two perpendicular surfaces. A tapered bur may reach further into an inside corner,
if the tool is at an inclined orientation, and the surface is closer to the tip. (Note: When working near the tip
of a tapered bur, the surface cutting speed is reduced.)
When deburring inside radii, a similar situation may arise. Do not attempt to deburr an inside radius less
than 1.5 times the diameter of the desired bur (Rmin = 1.5 x Cutter diameter). Depending on the depth
of cut, failing to follow these guidelines may result in excessive cutter contact resulting in excessive tool
chatter.
When running the robot program the first time, observe the path with the radial compliance air supply turned
down to approximately 0.35 bar (5 psi). When the robot path speed is increased, the robot may deviate from
the programmed path. Verify that at operational robot path speed, the bur is deflected but contacts the work
surface. Once the robot path is confirmed, the compliance force of the bur should be adjusted, as described
in
, in order to achieve a correct depth of cut
