แปลว่าคม

edge of a piece of fabric

แปลว่าชายผ้า

I was on edge the whole time

แปลว่าฉันรู้สึกตื่นตระหนกมาตลอด

Burr Mashers

แปลว่า(english) Devices used to remove build up on edge of strip after the slitting process.

Looking For Trouble

Back Rake

แปลว่า(english) The angular surface ground back from the cutting edge of cutting tools. On lathe cutting tools. The rake is positive if the face slopws down from the cutting edge toward the shank, and negative if the face sloopes upward toward the shank.

Bevel

แปลว่า(english) Angle formed between the prepared edge of the end of tube and a plane perpendicular to the surface. Standard pipe bevel is 30 degrees.

Bandsaw

แปลว่า(english) A power saw, the blade of which is a continuous,narrow,steel band having teeth on one edge and passing over two large pulley wheels.

Section Modulus:

แปลว่า(english) A property of a cross sectional shape, which depends on shape, and orientation. Section modulus is usually denoted S, and S = I/c, where I = moment of inertia about an axis through the centroid, and c is the distance from the centroid to the extreme edge of the section.

Burr

แปลว่า(english) The very subtle ridge on the edge of strip steel left by cutting operations such as slitting, trimming, shearing, or blanking. For example, as a steel processor trims the sides of the sheet steel parallel or cuts a sheet of steel into strips, its edges will bend with the direction of the cut.

Bars

แปลว่า(english) A relatively long straight, rigid piece pf metal; long steel products rolled from billets into such shapes as squares,rectangles, rounds,angles,channels,hexagons,and tees. In steel, “merchant bars” include rounds,flats,angles,squares,and channels that are used by fabricators to manufacture a wide variety of products such as furniture,stair railings and farm equipment. Concrete reinforcing bar (rebar) is used to strengthen concrete in highways,bridges and buildings.

Age Hardening

แปลว่า(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.
