Abstract: A Computer numerical control (CNC) machine includes a body; a touch screen, to display information and sense touch input of a user; and a processing unit, to obtain user information when the user logs in the CNC machine, generate a visual menu on the touch screen corresponding to the user information, and control the body to perform functions according to the touch input on the visual menu. A control method is also provided.

Abstract: In a method for managing a machining file including a series of procedures in sequence using a computing device, names of the series of procedures are displayed in a procedure list area of the management page. If procedures require to be combined, the method receives user-selected procedures to be combined from a database area of the management page, and combines the selected procedures into a new procedure according to a predetermined combination format. If the machining file requires to be stored, the method stores all the procedures in the procedure list area into the machining file in sequence, and stores the machining file in a storage system of the computing device.

Abstract: A display control system includes a memory system and an identifying control unit. The memory system is configured to store an identification code for an authorized operator of the display control system and an associated function interface for the authorized operator. The associated function interface comprises commonly used functions of the authorized operator, and an identification code of each authorized operators. The identifying control unit configured to receive and identify the identification code from the authorized user, invoke an instruction corresponding to the identification code from the memory system to generate the associated function interface, and control a display of the display control system to display the associated function interface.

Abstract: An encrypting system for numerical control devices includes a function module, a code module, a memory, and a controller. The function module includes function programs. Each of the function programs presetting a service life. The code module encrypts and decrypts the service life of each of the function programs. The memory stores the service life encrypted by the code module. The controller reads the encrypted service life from the memory according to an input instruction and controlling the code module to decrypt the encrypted service life, and comparing the decrypted service life with the current date to control the function program to be executed in response to the service life of the function program being valid.

Abstract: An operating device for a CNC machine includes an operating portion, an encoder, a memory unit, a microprocessor, a display unit, and a controller. The operating portion includes a rotary button and a confirm button. The encoder is connected to the rotary button and the confirm button for generating corresponding position codes. The memory unit stores a number of function menus corresponding to a number of operating instructions. The microprocessor is connected between the encoder and the memory unit for receiving the position codes from the encoder and invoking the corresponding function menus from the memory unit. The display unit is connected to the microprocessor for displaying the function menus. The controller is connected to the microprocessor for executing input instructions.

Abstract: A workpiece shifting prevention device includes a platform, which is configured for supporting a workpiece thereon; a sensor group mounted in the platform, which is configured for measuring pressures at different points on the platform and converting the pressures into voltage signals; an amplifier group connected to the sensor group, which is configured for amplifying the voltage signals output from the sensor group; and a single chip connected to the amplifier group, which is configured for receiving and processing the amplified voltage signals. The single chip checks if the voltage signals output from the sensor group are equal, and if not, adjusting machining parameters of an implement connected thereto.
