   7 hours ago · Of course, this is not absolute. The specific choice also needs to be comprehensively considered and adjusted according to the specific situation of the steel structure, rust removal and polishing requirements, and process conditions. Sometimes it may also be necessary to combine steel shots of different sizes to achieve a more ideal effect.

   7 hours ago · Comedy films are separated into two categories: short films and feature films. Any film over 40 minutes long is considered to be of feature-length (although most feature films produced since 1950 are considerably longer, those made in earlier eras frequently ranged from little more than an hour to as little as four reels, which amounted to about 44 minutes).

   7 hours ago · The main reason for the difficulty in machining high-temperature alloys is its high hardness, high toughness and high thermal stability. During the cutting process, it is easy to cause tool wear, thermal deformation, high surface roughness and other problems, and the machining cost is high and the cycle is long. This article introduces the reasons for the difficulty in machining high ...

   What is roughness and why is it important?

   • The roughness of a surface determines how an object will interact with its surrounding environment. Rough surfaces tend to wear down more quickly in addition to having higher friction, though they tend to have better adhesion properties. Ra, the arithmetic average roughness, is the most widely used parameter for roughness.

   What is a good roughness value?

   • A high roughness value spreads the light more evenly in all directions. What the right value is depends on the material you want to simulate. Better: If you have a roughness of 0, the amount of light a surface reflects depends mostly on how much the surface is facing the light source.
