车刀的副偏角，对工件的（  ）有影响。

BlackTom AI · Accepted Answer

In this question about the effect of the tool's auxiliary offset angle on the workpiece, we must evaluate what each potential outcome is most influenced by.
Option 1: 尺寸精度 (dimensional accuracy). Dimensional accuracy is primarily governed by geometric relationships, tool path accuracy, machine stiffness, and thermal expansion. While the auxiliary offset angle may have some indirect influence via cutting forces, it is not the main factor determining the overall size tolerance of the part.
Option 2: 形状精度 (shape accuracy). Shape accuracy relates to the precise contour and form of features, which depends on tool geometry, path control, and machine accuracy. Although an offset angle can affect how smoothly a feature is generated, the core determinants of shape accuracy are more closely tied to tool geometry and programmed trajectories rather than the auxiliary offset angle alone.
Option 3: 表面粗糙度 (surface roughness). Surface roughness is highly sensitive to the cutting edge geometry, chip formation, cutting speed, feed rate, and, notably, the orientation of the tool relative to the workpiece. The auxiliary offset angle directly influences the cutting edge engagement, contact mechanics, and vibration behavior, which primarily manifest as changes in the finished surface texture and roughness. Therefore, this option aligns best with the expected effect.
Putting these together, the auxiliary offset angle is most closely associated with how smooth or rough the surface is, rather than the overall dimensions or the gross shape of the part. Consequently, the incorrect options misattribute the influence to aspects more governed by other machining parameters or broader geometrical control, not the offset angle itself.
