Final answer:
A gang-tool lathe has multiple tools mounted along the cross-slide, optimizing for quick tool changes and efficiency in high-production environments. This type of lathe is ideal for simpler parts that require fewer tool changes, in contrast to turret lathes or machining centers designed for more complex operations. The correct option is B. gang-tool late
Step-by-step explanation:
A lathe that has multiple tools mounted along the cross-slide is known as a gang-tool lathe. Unlike a basic CNC lathe or a turret lathe, the gang-tool lathe has a setup where multiple tools are fixed in a gang on the cross-slide, allowing for quick tool changes and reducing cycle times. This design contrasts with turret lathes, where tools are indexed into position by rotating the turret, and machining centers, which are highly automated and can perform a variety of operations but have a different configuration.
Gang-tool lathes are efficient for parts requiring multiple operations, as they can perform these without the need for changing tools or indexing a turret. This type of lathe setup is particularly beneficial in high-production environments where time saved on tool changes translates directly into increased productivity. However, the number of tools that can be mounted is limited compared to a turret lathe, which may have a larger number of tool positions available for use.
When selecting a lathe, factors such as the complexity of the parts, production volume, and specific manufacturing needs should be considered. The gang-tool lathe might be the optimal choice when looking to maximize efficiency for simpler parts that require fewer tool changes, while a turret lathe or a machining center might be better suited for more complex parts or operations.
