Final answer:
The correct option is A. The cross-slide travel on a gang-tool setup on a basic CNC lathe is commonly limited to a range of 6" to 12", to accommodate various tools and allow efficient operation.
Step-by-step explanation:
The cross-slide travel on a gang-tool setup in a basic CNC lathe is typically designed for working on small and precise components, with travel distances that are relatively compact compared to other types of lathes. Commonly, the cross-slide travel for this kind of setup is limited to accommodate various cutting tools in close proximity to each other for efficient operation and to allow quick changes between operations without significant reconfiguration of the tooling.
Based on the older "rule of thumb," which suggested 5 inches side-to-side and 7-8 inches deep, and considering advancements in technology allowing for as much as 8 diameters side-to-side and 15 diameters deep, the cross slide travel on a gang-tool setup on a basic CNC lathe usually falls within a range that could be considered between 6" to 12" (option A). It's essential to keep in mind that specific machines might have different capabilities based on their design and manufacturer specifications.
