Abstract: An automatic angle-measured apparatus includes a driving unit coupled with a clamping plate and a driving seat, an encoding unit located at an end of the driving unit facing the driving seat and signally connected to the driving unit, at least one attitude sensor located at the driving seat, and a control unit signally connected to the encoding unit and the attitude sensor. The attitude sensor senses the un-rotated and the rotated driving seat to generate a first and a second signals, respectively. The control unit bases on the first and the second signals to calculate an offset. The control unit controls the driving unit to rotate a predetermined angle. The encoding unit bases on the predetermined angle to generate location information. The control unit bases on the first signal, the second signal and the location information to calculate angle information and compensation for performing a correction procedure.

Abstract: A method for predicting collision of a machining path includes: a step of reading an NC program; a step of translating a plurality of block information in the NC program; a step of, prior to perform interpolation upon each of the plurality of block information, calculating a safety distance of a next block information with respect to a block information to be interpolated; a step of searching a number of individual block information having an accumulated distance greater than or equal to the safety distance; and a step of performing an anti-collision detection upon each of the individual block information contributing the accumulated distance. In addition, a system for predicting collision of a machining path is also provided.

Abstract: A machine tool collision avoidance method includes: loading multiple processing codes; simulating multiple path traces corresponding to the processing codes; estimating multiple execution periods for running the path traces; selecting the shortest execution period from the execution periods; determines whether the distance between the trace point points on any two of the path traces is less than a safety distance within the shortest execution period; if the distance between a first trace point on a first path trace and a second trace point on a second path trace is less than the safety distance, estimating a first time point at which a first turret runs to the first trace point and a second time point at which the second turret runs to the second trace point; generating a collision warning if the difference between the first time point and the second time point is lower than a tolerance value.
