4.2 Normal Operation
The following sections describe the normal operating conditions for CDB.
4.2.1 Air Quality
The air supply should be dry, filtered, and free of oil. A coalescing filter with elements rated for 5
micron or better is required. The air must be supplied to the ATC collet at between 1‑4.1 bar (15‑60
psi) and to the ATC tool stand at 4.1 bar (60 psi).
Particulate can block airflow or impede compliance motion. If deburring tools do not receive proper
air pressure, tool may not re‑center properly. Any water in the system damages the housing and
blades.
4.2.2 No Lubrication
The compliance device cannot have any oil in the air supply. Oil can clog compliance device and
limit compliance range.
4.2.3 Blade Selection and Maintenance
CDB accepts industry standard, off the shelf hand deburring blades. As blades near end of their
service life, surface finish may degrade, necessitating change of blade.
Radially loaded blades and scraper tools as well as axially loaded countersink tools are acceptable.
Always ensure the ball detent and locking divots on tool holder shaft are aligned radially and that the
ball is securely seated in the divot. Unsecured blades can cause the shaft to slip, creating hazards for
operators and quality.
4.2.4 Deburring Tool Approach Path Should be Slow and at an Angle
The deburring tool should approach the workpiece slowly and at an angle, with ample room for
pivoting blade to reorient before beginning each pass.
When beginning a deburring pass, try to minimize the initial impact on the work piece by slowly
approaching the tool at an angle while maintaining a parallel path with the surface.
If the tool quickly approaches perpendicularly to the workpiece, the result is gouging and
premature wear of the tool bearings and bur. Additionally, collisions could result and create a
hazardous situation for both personnel and equipment.
When using pivoting blades, approach from a distance and angle for the blade to catch on the
workpiece edge. Program the robot accurately when the contact holes are geometrically equal to or
less than the tool’s pivot radius.
Note: some tools are directionally dependent. Before use, always verify the intended direction of
blade operation.
4.2.5 Single Axis Loading
While using single axis lockout, do not apply radial loads that are perpendicular to the axis of pivot.
Always keep the tool pivoting perpendicular to the deburring surface. Loading the tool along the pivot
axis will damage the pivot pins and cause premature failure.
4.2.6 Program the Robot to Incorporate 50% Compliance Travel of the Tool
Program the robot to have the tool’s compliance at 50% travel when on the nominal path.
As the part’s edge deviates from the perfect path, the bur can use compliance to follow along high
and low spots without losing contact or hitting the positive stop and gouging. Do not “bottom out” the
compliance and hit the positive stop.
Repeated impacts on the positive stop create slop in the compliance and reduce recentering
repeatability.
