Define the Polishing Requirements
The application mounts a rotating polishing tool on a UR robot, moves it along a surface, and attempts to maintain constant contact force. The available evidence does not define the required force, allowable force error, part geometry, tool speed, or process duration. Establish those values before deciding whether UR force mode alone is sufficient or whether an FT300 is required.
| Decision input | Evidence status | Required action |
|---|---|---|
| Target contact force and allowable error | Not specified | Define measurable acceptance limits. |
| Part shape and tool path | Not specified | Identify surfaces, transitions, and path directions. |
| Force-control method | UR force mode or FT300 under consideration | Compare both methods on the same process. |
| Rotational disturbance | Expected, not measured | Capture force data with the tool rotating. |
| Dust and service life | Identified as concerns | Verify environmental and durability requirements separately. |
Select the Force-Control Architecture
The project assumption is that the desired force accuracy may exceed what UR force mode alone can deliver, but the evidence contains no comparative test results. Treat that claim as a hypothesis. Test UR force mode first against the defined force-error limit, then add the FT300 and repeat the identical path, tool, surface, and operating conditions.
A compliant polishing tool is another architecture to evaluate. Compliance may accommodate surface variation mechanically, but the evidence provides no performance data showing whether it can replace sensing or active force control. Select among robot-only control, FT300 feedback, and tool compliance using measured process results.
Measure Rotational Signal Disturbance
The rotating tool is expected to introduce noise into the force signal. The evidence does not establish its amplitude, frequency content, or effect on finish quality, so do not select filtering or control settings by assumption.
- Record the force signal with the tool stationary and unloaded to establish a baseline.
- Record it with the tool rotating before surface contact to isolate rotation-related disturbance.
- Run the polishing path under controlled contact and compare measured force error with the acceptance limit.
- Repeat the test for each candidate architecture and inspect both force stability and the polished surface.
Verify the Industrial Design
Force performance alone does not qualify the system for production. The project also raises robustness, dusty-environment operation, equipment cost, and multi-year service as selection concerns. No environmental ratings, duty-cycle limits, maintenance intervals, or lifecycle data are provided, so obtain those specifications from the relevant manufacturers and compare them with the documented operating environment.
Approve the design only after the chosen configuration meets the force-error requirement, produces an acceptable finish, remains stable with the tool rotating, and satisfies the environmental and durability requirements. If results differ between part shapes or path regions, qualify each geometry rather than generalizing from one surface.
FAQ
Is an FT300 required for UR robot polishing?
The evidence does not prove that it is required. Compare UR force mode and FT300 feedback on the same polishing path against a defined force-error limit.
How do I diagnose force noise from a rotating polishing tool?
Compare force recordings with the tool stationary, rotating without contact, and rotating during polishing. This separates the baseline signal from rotation-related disturbance and contact-process effects.
What must be specified before selecting polishing force control?
Define the target contact force, allowable force error, part shape, tool path, environmental conditions, durability requirement, and acceptable surface finish. The supplied evidence does not provide values for these criteria.
