A ________ should precede the drilling processQuestion 8Select one:a.spade drillingb.center drillingc.facingd.turninge.boring

To approach the question of what should precede the drilling process, we must first understand the context of drilling in manufacturing or construction.

Breakdown of the Problem

1. Identify what each option refers to concerning drilling.
2. Determine which option logically precedes the drilling process.

Relevant Concepts

• Spade Drilling: Typically used for creating larger holes and not a preliminary step.
• Center Drilling: This method creates a small pilot hole to align the subsequent drilling accurately.
• Facing: Involves machining a flat surface and does not precede drilling.
• Turning: Refers to machining operations on a lathe, not specifically related to the drilling process.
• Boring: A method of enlarging an existing hole, typically not a precursor to drilling.

Analysis and Detail

Center drilling involves creating a smaller hole at the center of the intended drill location, providing proper guidance for the larger drill bit. This step is crucial to ensure accurate hole placement and prevent drill bit wandering during the drilling process.

Verify and Summarize

Considering the roles of each option, center drilling is the logical answer as it specifically precedes drilling to enhance accuracy.

Final Answer

b. center drilling should precede the drilling process.
