The correct answer is: A. logic
The four basic elements required for an automated machine tool or production process are:
- Input interface: This is the part of the system that allows the user to input data into the system. This can be done manually, through a keyboard or mouse, or automatically, through sensors or other devices.
- Memory: This is where the system stores data. This data can include the program that is being run, the current state of the machine, and any other information that the system needs to keep track of.
- Output interface: This is the part of the system that allows the system to output data. This can be done to a display, to a printer, or to another device.
- Logic: This is the part of the system that controls the operation of the machine. It takes the input data, stores it in memory, and then outputs the appropriate commands to the machine.
NC tape programming is a method of programming automated machine tools that was developed in the 1950s. It involves using a punched tape to store the instructions for the machine. The tape is then read by the machine and the instructions are executed. NC tape programming is no longer widely used, as it has been replaced by more modern methods of programming, such as computer-aided manufacturing (CAM).
A computer graphics workstation is a computer that is used for creating and displaying graphics. It typically has a high-resolution display, a powerful graphics processor, and specialized software for creating and editing graphics. Computer graphics workstations are used in a variety of industries, including architecture, engineering, and entertainment.
In conclusion, the correct answer is: A. logic. The other options are incorrect because they are not essential elements of an automated machine tool or production process.
