英文摘要：

How to inspect machining accuracy is a crucial problem to complex components and very large components.It is one of the key issues to be solved in the domain of advanced manufacturing technology.On-machine inspection technology is a new tool which can be used for the purpose right after the machining operation.It has a very good prospective application range due to its convenient,fast installment and without second part setup.It presents the overall structure of the proposed on-machine inspection system,and describes its main function modules.It also provides the implementing method for the key modules, such as measure point distribution,probing tool path generation and simulation,error compensation.
