Why do some machine-carved furniture pieces still need hand finishing?

In the furniture industry, machine-carved pieces require hand finishing because the initial mechanical process is designed primarily for efficiency rather than detail.

When producing intricate items like furniture legs, manufacturers often use multiple-spindle carving machines. These machines utilize a follower point to trace a master model, which then guides high-speed rotating knives to whittle the wood blanks into the desired shape. While this process effectively creates the rough form, it lacks the precision and artistic nuance of a human touch. Consequently, after this rough woodcarving stage, the pieces must be finished by a hand carver to refine the details and ensure the quality of the final product.1

This reliance on manual labor is a broader characteristic of the industry; even in mass-production factories, some hand operations remain necessary because they are essential for maintaining quality where machines would otherwise compromise the final result.23
