Centroid:

แปลว่า(english) Similar to the concept of center of gravity, except that it applies to a two dimensional shape rather than an object. For a given shape, the centroid location corresponds to the center of gravity for a thin flat plate of that shape, made from a homogeneous material.

Batch Anneal

แปลว่า(english) The process by which a large, stationary stack of steel coils (4 coils high) is subjected to a long heat-treating cycle. This process enables the cold-rolled sheet to fully recrystallize into the softest possible product conforming to customer specifications. Controlling the recrystallization process makes a fine-grained microstructure easy to obtain, and minimizes the tendencies for retention of directional properties of the rolled steel which could produce undesirable shapes in the stamping of a cylindrical part such as a can. Also see Anneal and Continuous Anneal.

Elastic energy:

แปลว่า(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

Degree of Freedom:

แปลว่า(english) A displacement quantity which defines the shape and location of an object. In the two dimensional plane, a rigid object has three degrees of freedom: two translations and one rotation. In three dimensional space, a rigid object has six degrees of freedom (three translations and three rotations).

Bull Gear

แปลว่า(english) The large crank gear of a shaper.

Bending

แปลว่า(english) A preliminary forging operation to give the piece approximately the correct shape for subsequent forming.

Bending Angle

แปลว่า(english) A 'V-shaped' piece of angle iron attached to the rear of the coil car in the Strip Steel, which is used to help the operator put bends into the front end of a coil.

Consolidation

แปลว่า(Concrete Engineering) Compaction usually accomplished by vibration of newly placed concrete to minimum practical volume, to mold it within form shapes and around embedded parts and reinforcement, and to eliminate voids other than entrained air.

x-frame, x-shape chair, x-stool , x-stretcher, x-table

Broach

แปลว่า(english) A long, tapered cutting tool with serrations which,when forced through a hole or across a surface, cuts a desired shape or size.

Brale

แปลว่า(english) A diamond penetrator, conical in shape, used with a Rockwell hardness tester for hard metals.

Z-Mill

แปลว่า(english) The full name for z-mill is Sendzimir mill. A Z-mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid-shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Z-Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.
