What is meant by "program nesting" in CNC programming?

Program nesting refers to the technique of grouping multiple parts or components into a single CNC program. This approach is particularly beneficial in manufacturing environments where efficiency and material utilization are critical. By nesting parts within a single program, operators can optimize the use of material, minimize waste, and streamline production processes.

This method allows for the simultaneous machining of several parts, which can lead to increased productivity and reduced cycle times. It also simplifies program management since operators deal with one program instead of multiple individual programs for each part, making it easier to handle changes or updates.

The other options focus on different aspects of CNC programming but do not accurately describe the specific concept of program nesting. For instance, modifying programs for different materials involves adjustments to accommodate various machining characteristics but does not relate to the grouping of multiple parts. Running programs in parallel suggests a different operational capability, while storing programs on the cloud pertains more to data management and accessibility rather than to the actual organization of parts within a program.
