Start with the process
Document the current method, cycle time, number of operators, part presentation and finish requirement. Include what happens before and after blasting, because those steps often determine whether automation delivers a real throughput gain.
Match complexity to the application
Use the simplest architecture that can repeatably meet the requirement. A servo turntable and fixed nozzles may outperform a robot in a simple application; a robot may eliminate multiple axes and fixtures on a complex part.
Design for production ownership
Maintenance access, wear parts, diagnostics, recipes and safe recovery from faults should be designed in from the beginning. The machine must be maintainable by the plant that owns it, not only by the engineer who commissioned it.
Build the business case
Compare total cost per acceptable part before and after automation. Include labor, rework, overtime, capacity constraints, maintenance and the value of consistency.
Frequently Asked Questions
What information is most important for an automation concept?
Part drawings or photos, size and weight, desired surface result, abrasive, current cycle time, production volume and available utilities.
Should I start with a robot?
Only if the geometry or product mix requires that flexibility. Simpler motion should be evaluated first.
How do I reduce project risk?
Validate the blasting process, define acceptance criteria and lock down part handling and cycle requirements before detailed machine design.
