A grinding wheel's surface texture has a strong influence upon its grinding performance. This is clearly evidenced by the increase in grinding forces, power consumption, and cutting zone temperatures as a wheel wears [Butler and Blunt, 2002]. If the surface texture of a grinding wheel could be measured and quantified, then it could be

The micro-textured inserts have significant effects on cooling and lubrication performance in the cutting zone, which may decrease the adhesion wear and cutting force up to 30% [10, 11]. Experimental studies showed that regular textures on the tool surface reduce the tool-chip interaction's actual surface, decreasing the friction coefficient ...

Friction is the main factor related to the reliability and durability of mechanical equipment. The main problems of machining difficult-to-cut material are violent friction of cutting area and an increase in tool wear caused by high cutting temperature. To solve these problems, surface texture has become an effective way since it can reduce cutting force and …

Mobile projects must balance frame rates against battery life and thermal throttling. Instead of pushing the limits of your device at 60 fps, consider running at 30 fps as a compromise. Unity defaults to 30 fps for mobile. You can also adjust the frame rate dynamically during runtime with Application.targetFrameRate.
