This paper reports the author’s recent work to improve the measuring performance of the autonomous form measuring device developed previously,which is applicable to autonomously inspecting profiles of free form surfaces on a machining *** main improvements includes acceptation of a gap sensor to precisely detect the reference position along a canning line,an AC servo motor to smoothly perform the autonomous movement following the profile to be measured,and a new type of laser displacement detector to enhance the measurement capability to the different states of *** results of verification experiments with the new device sufficiently demonstrate the effectiveness of these improvements.

Cast blanks with large-scale free form surfaces are very difficult tomanufacture because of significant casting distortions. It is concerned that the development andapplication of a hogging algorithm for preparing the blanks for an extended rough cutting. Theprocedure includes three main phases. They are the reconstruction of the free form surface withscattered points based on a special Hermite's interpolation, intersection of curved surfaces todefine the hogging areas, and the tool path planning. The result shows that the algorithm is greatlyvalid in reducing the invalid tool paths so that the work efficiency can be improved remarkably.
