← TechnologyWhich outcome occurs because of insufficient resolution controlling depth-of-cut in CNC lathe during continuous surfacing?
A)Increased surface roughness occurs✓
B)The tool deflects excessively inward
C)Cutting tool experiences immediate fracture
D)The workpiece undergoes phase transformation
💡 Explanation
Increased surface roughness occurs because the resolution limits the smallest achievable depth, leading to inconsistent material removal due to the **quantization error**, which presents as surface variations. Therefore, roughness increases, rather than immediate fracture or uniform deflection which occur at much larger tolerance exceedances.
