True or False: The cutting edges of the largest step of the reamer should extend slightly beyond the far edge of the part when setting the drill stop.

The statement is true because when setting the drill stop on a reamer, the cutting edges of the largest step should indeed extend slightly beyond the far edge of the part being worked on. This ensures that the reamer effectively cuts the material to the desired depth and achieves the required surface finish and dimensional accuracy. Extending the cutting edges beyond the material also allows for proper engagement of the tool with the workpiece, preventing issues like gouging or uneven surfaces which might occur if the reamer does not fully traverse the intended area.

Ensuring that the cutting edges are positioned correctly is crucial for precision in aerospace applications, where tolerances are often very tight. It allows for effective removal of material and reduces the risk of tool binding within the hole. Proper setup contributes to the performance and reliability of the finished assembly, which is imperative in aerospace assembly where safety is paramount.
