Oblique cutting and surface generation Consider oblique cutting (tool cutting edge inclined to the direction of cutting). Is it true that the tool may or may not generate a surface parallel to the tool face, depending on the inclination and geometry?

Introduction / Context:
Machining can be analyzed as orthogonal or oblique cutting. In oblique cutting, the cutting edge is inclined, altering chip flow direction and the kinematics of the generated surface.

Given Data / Assumptions:

• Tool has nonzero inclination angle (lambda) with respect to cutting velocity.
• Work material and feeds are typical; no special chip-control grooves considered.
• Surface generation depends on effective rake and edge orientation.

Concept / Approach:
Unlike orthogonal cutting where the cutting edge is perpendicular to the cutting direction, oblique cutting deflects chip flow sideways. The geometry can yield a generated surface that is not strictly parallel to the tool face; it depends on rake, inclination, and approach angles. Thus, it is correct to say the tool may or may not generate a surface parallel to the face.

Step-by-Step Solution:

Verification / Alternative check:
Machining theory shows the chip flow angle eta and the normal rake governing chip direction; graphical kinematics confirm nonparallel outcomes are common in oblique cutting.

Why Other Options Are Wrong:
“No”: contradicts geometric reality of oblique cutting.Material-specific or rake-specific qualifiers are unnecessary; geometry alone dictates the relationship.

Common Pitfalls:
Assuming orthogonal cutting relations apply directly to oblique cutting; overlooking the role of inclination angle in surface generation and chip disposal.

Final Answer:

Yes
