Numerical Control Of Machine Tools - 1
Posted on 11-Apr-2021
Can you tell me one of the worst shop accidents you have witnessed and how you think it could have been prevented? Can you share a time you successfully mentored a colleague and helped them improve their skills? What steps did you take and in what ways were they receptive? Do you adapt well to new machinery? Asking this question tests how important the CNC operator candidate considers machine maintenance to be. It also will indicate how much experience they have with maintenance and machine troubleshooting. If they have work experience, they should be able to relate specific examples when answering the question. We were provided guidelines by the process engineer and the user manual to follow. CNC machining involves creating precision parts in various ways, and CNC operators are usually responsible for checking that the parts they produce meet specific dimension measurements. Operators should understand tolerances and be familiar with quality control practices.

Pay attention to how much detail the candidate pays to balancing production against quality assurance and the importance of adhering to a manufacturing process. They should also be familiar with accurate measuring techniques and tools. I especially watch for easily missed or critical measurements. CNC operators sometimes encounter complex part drawings that require a multi-step manufacturing process. Most experienced candidates will have an example they can share without much trouble. Asking this question helps you gauge how much experience the candidate has with complicated CNC programs. It can also give you an idea of how efficiently they can handle problems with programs that need code changes or measurement adjustments. I needed to adjust several program steps with the help of a process engineer.

The programmer will select the necessary tools that are used in cutting, and also in establishing the sequence of operations of the machine's operations. What Is Turning Operation? Answer : Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. Answer : A lathe is a machine tool that rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the workpiece to create an object with symmetry about an axis of rotation.

Show the interviewer, in as simple terms as possible, that you understand MCU function and capabilities. Rachelle's Answer "The primary function of an MCU is to read the coding instructions, and to send correct instructions to each part of the machine as it recognizes and interprets axis transfer commands. An MCU is also used to support the axis movement controls and amplifier circuits for managing the axis tools. It holds the reviewed signals of location and velocity for each drive axis. It also executes auxiliary control purposes like coolant or tools. The MUC receives all the information as to what is required and then sends the information to the proper tools to follow through on the job.
