How does an improperly aligned workpiece affect machining?

• A. It can improve the machining time
• B. It has no effect on the output
• C. It leads to inaccuracies in the finished part
• D. It can save on tooling costs

Answer: (C)

An improperly aligned workpiece can lead to inaccuracies in the finished part because precise alignment is critical for achieving the desired tolerances and specifications during machining operations. When a workpiece is not aligned correctly, the cutting tools may not engage the material uniformly or as intended, which can result in uneven cuts, misaligned features, or dimensions that do not meet the required specifications. This misalignment can cause issues such as improper hole placement, misfit parts, or variations in surface finish. Ultimately, these inaccuracies can necessitate rework or result in considerable waste, significantly affecting production quality and costs. The alternatives provided do not effectively capture the consequences of improper alignment. For example, any suggestion that misalignment could improve machining time is misleading; inefficiencies are more likely to arise from the need to correct errors. Similarly, the idea that there is no effect on output ignores the fundamental principle that alignment accuracy directly influences the overall quality of the machined part. Lastly, suggesting that improper alignment could save on tooling costs overlooks the increased likelihood of tool wear or damage resulting from misaligned operations. Thus, maintaining proper alignment is essential for achieving precision in CNC machining and avoiding costly errors.
