What should be considered first when choosing a processing sequence for mold cavities?
Finishing is the final stage, focusing on achieving precise dimensions and surface quality.
Semi-finishing follows roughing, further refining dimensions before final touches.
Roughing is essential for quickly removing excess material, setting the stage for finer processes.
Surface treatment occurs after machining to enhance properties like wear resistance.
Roughing is the initial step in processing, removing excess material to prepare for semi-finishing and finishing. It involves using larger tools and greater depths, unlike finishing, which focuses on detail.
What is the recommended machining process for cavities with thin-wall structures to prevent deformation?
This process focuses on minimizing heat impact and ensuring accuracy, crucial for maintaining the integrity of thin walls.
This method is more suitable for creating deep cavities rather than handling thin-wall structures.

Why is it important to consider the hardness of mold materials during the machining process?
While cutting fluid is important, hardness mainly influences tool selection and machining strategy.
Hardness impacts both the choice of tools and machining strategies for effective material removal.
Design considerations are influenced by functional requirements, not solely material hardness.
Heat distribution is managed by machining techniques and cooling systems, not material hardness.
The hardness of mold materials significantly influences the choice of tools and machining parameters. Harder materials require more robust tooling and adjusted machining speeds to prevent excessive wear and ensure efficient processing. This consideration helps maintain surface quality and prolong tool life.
