Touch-trigger probes (TTPs) have been commonly utilized in on-machine measurement (OMM) by virtue of their low cost and high repeatability. The pre-travel error (PTE) compensation the probe is one critical issues improving OMM precision. majority existing studies on PTE five-axis adopt same strategy as three-axis OMM. Thus, discrepancies between two processes principles are ignored, which results poor accuracy for measured results. In this paper, a novel presented to accurately compensate...
Abstract As an important technology of adaptive machining, on-machine measurement (OMM) is always used to measure the shape to-be-cut surface. Due multi-source errors in OMM system, confidence accuracy becomes particularly before planning next cutting procedure. implemented by multi-components involving machine tools, fixture, and probe. Each component introduces uncertainty error into result. The positioning error, alignment eccentricity are investigated terms expectation, uncertainty,...
To ensure impeller fabrication accuracy, the blades are necessary to be inspected on machine tool (MT) correct machining deviation. Plagued by overlapping structures of and positioning errors from multiaxis MT, it is a challenge generate an on-machine inspection (OMI) path that simultaneously guarantee measurement efficiency accuracy. On one hand, improve efficiency, stylus can stay in channel during process reduce idle paths. other rotary axis reduced as much possible For achieving these...
Abstract On-machine inspection is an important technology for the precision fabrication. Plagued by overlapping structure and positioning error from machine tool, it a challenge to generate on-machine path. In this paper, rotation theory investigated balancing efficiency accuracy. Based on kinematic chain of accessible space graph established demonstrate theory. The least rotations, direction reversions can be recognized graph. term these principles, orientation planning method proposed...
The blades are necessary to be inspected on the machine tool avoid unnecessary error sources from re-clamping. Plagued by overlapping structures of impeller and positioning multi-axis tool, it is a challenge generate an on-machine inspection path for balancing efficiency accuracy. To improve efficiency, stylus stays in blade channel during process reduce idle paths. In order accuracy, rotary axes maintained as much possible errors. reach these targets, least times rotation optimization model...
In on-machine measurement (OMM), the positioning error of machine tool affects relative position and orientation between probe workpiece. This introduces errors into result, which make workers question accuracy OMM. Therefore, clarifying relationship OMM is helpful to this technique more reliable. For purpose, a five-axis model considering proposed. First, paper gives definition feasible region (FMR) about tool, obtains under known features. Then, prediction established, can be used predict...
