The invention discloses a machine tool simulation instrument for a numerical control system, and the instrument comprises a controller, an interface circuit, and a display, wherein interface circuit and the display are correspondingly connected with the controller. The interface circuit comprises a feed signal input interface, a main shaft signal input interface, a simulation coder output interface, a switching quantity input interface, and a switching quantity output interface. The instrument can be in direct butt joint with a main interface on a numerical control device, and enables the numerical control device to be able to operate under the condition of being separated from an electrical control cabinet and a machine tool mechanism through virtualizing operation conditions of the circuit and programs in the instrument and the peripheral equipment of the numerical control device, a servo driver, a main shaft driver, a motor, a transmission mechanism, a limiting switch, and a switching quantity load. The instrument also can visually display the operation conditions of the peripheral circuits of the numerical control device and the machine tool mechanism on a display, thereby facilitating the testing, debugging and fault detection of the numerical control device, and avoiding the debugging and maintenance dangers of a true machine tool.
Description
technical field [0001] The invention relates to the technical field of numerical control system debugging and fault diagnosis, in particular to a numerical control system machine tool environment simulator. Background technique [0002] The CNC device can work normally in a complex CNC system environment. The working environment of the CNC system includes the CNC device, the power supply system, the servo driver, the spindle driver, the motor, various sensors and actuators, and the machine tool kinematic mechanism. The function of the numerical control device is embodied by its internal computer system executing numerical control parameters, PLC programs and processing codes, inputting and outputting corresponding control signals, and finally making the machine tool produce corresponding motions. [0003] When a numerical control device and its peripheral components are used to form a numerical control system, how to quickly debug and verify the correctness of the parameters...
