How to assess the precision requirements of a project and determine if the precision requirements stated by the client can be achieved.
The precision requirements vary across different industries and scenarios. Currently, Mech-Mind is involved in various industrial scenarios, including heavy industry, logistics, automotive, and household appliances, each with distinct application contexts. Based on experience, some common project precision requirements can be summarized as follows:
In the heavy industry sector, a prevalent application scenario is workpiece loading. The overall precision requirement for such projects usually ranges from ±3 to ±6mm. Some workpiece positioning scenarios might demand accuracy within ±0.5mm.
In the logistics industry, common application scenarios include palletizing and depalletizing and supply packaging for express delivery. The precision requirement for these projects is approximately ±5mm.
In the automotive industry, tasks predominantly involve positioning, assembly, adhesive application, and high-precision grasping. Hence, the project precision requirement typically falls below ±1mm.
In the household appliances industry, tasks primarily revolve around workpiece loading, but the precision demand is higher than in the heavy industry sector, typically around 1mm.
Specific project precision assessment necessitates presenting an actual project plan and conducting testing. With a thorough understanding of customer requirements, the assessment considers factors such as robot precision, vision system accuracy, environmental influences, project complexity, and their potential impact on overall project accuracy. By testing the actual solution, comparing it against customer demands, the feasibility of meeting precision requirements can be determined.
