What is one method to prevent warping of a workpiece during milling?

• A. Using a lower cutting speed
• B. Applying excessive lubrication
• C. Using proper fixturing or clamping techniques
• D. Increasing the depth of cut

Answer: (C)

Utilizing proper fixturing or clamping techniques is essential for preventing warping of a workpiece during milling. When a workpiece is securely clamped, it minimizes movement and vibration during the machining process, which can lead to distortion. Properly distributing the clamping forces can also help avoid creating stress points that may cause the material to flex or warp, especially in materials that are sensitive to heat generated from cutting or materials with internal stresses. Inadequate or improper fixturing can allow the workpiece to shift, leading to uneven cutting forces and potentially causing the material to change shape under pressure. Therefore, ensuring that the workpiece is immobilized correctly not only enhances machining accuracy but also preserves the integrity of the material throughout the milling operation.
