Final answer:
The statement is false; a circle in the surface texture symbol means no material removal by machining is required. The absence of a circle typically indicates a machined surface.
Step-by-step explanation:
The statement is false. If the surface texture symbol in a technical drawing contains a circle, it indicates a surface that does not require the removal of material by machining, or it can be produced by processes other than machining. The absence of a circle generally means that the surface must be machined. Engineering drawings use a set of symbols to convey information about the manufacturing and finishing of parts. Understanding these symbols is crucial for engineers, manufacturers, and anyone involved in the production process of mechanical components.
