Abstract:
1. A system for controlling movement of a measurement machine, the system comprising a computer connected to the measurement machine via a control card, the computer comprising: at least one processor executing programs stored in a storage system of the computer, the programs comprising: a setting module to set motion ranges of a movable arm moving on a motion shaft of the measurement machine, the motion ranges comprising a normal motion range, a first deceleration motion range and a second deceleration motion range; an obtaining module to obtain a motion offset of a joystick when the joystick is operated along an operating direction; the setting module also to set an association between a motion direction of the movable arm and the operating direction of the joystick according to the motion offset; a calculating module to calculate a first speed of the movable arm when the movable arm moves in the normal motion range; the setting module further to set a second speed of the movable arm if the movable arm moves in the first deceleration motion range, and set a third speed of the movable arm if the movable arm moves in the second deceleration motion range, and a sending module to send a shifting instruction to the control card to control the movable arm to move at the corresponding set speed along the set motion direction according to the corresponding deceleration motion range of the movable arm, and to send a stop instruction to stop movement of the movable arm when the movable arm reaches a limit position.
