Bell Mouth

แปลว่า(english) The flaring or tapering of a machined hole, usually made at the entrance end because of misalignment or spring of the cutting tool.

Jacking Force

แปลว่า(Concrete Engineering) The temporary force exerted by the jacking device which introduces tension into the tendons. Jacking Stress In prestress concrete, the maximum stress occurring in a tendon during stressing.

สปริง

หมายถึง[สะปฺริง] น. สิ่งที่ยืดหรือหดแล้วคืนตัวได้เอง มักทำด้วยโลหะ เช่น นาฬิกาเรือนนี้สปริงหลุด จึงไม่เดิน. ว. ที่ยืดหรือหดแล้วคืนตัวได้เอง เช่น เบาะสปริง เตียงสปริง. (อ. spring).

กับแก้

หมายถึง(ถิ่น-พายัพ) น. ชื่อไม้ล้มลุกไร้ดอกชนิด Selaginella argentea (Wall. ex Hook. et Grev.) Spring ในวงศ์ Selaginellaceae ใช้ทำยาได้ ใบอ่อนใช้เป็นผัก, พ่อค้าตีเมีย ก็เรียก.

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.

Butcher Saw Steel

แปลว่า(english) A hardened, tempered, and polished high carbon spring steel strip material (carbon content is generally higher than that of a material used for wood band saw applications) with a Rockwell value of roughly C47/49.

Band Saw Steel (Wood)

แปลว่า(english) A hardened tempered bright polished high carbon cold rolled spring steel strip produced especially for use in the manufacture of band saws for sawing wood, non ferrous metals, and plastics. Usually carries some nickel and with a Rockwell value of approximately C40/45.

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.

Break Test (for tempered steel)

แปลว่า(english) A method of testing hardened and tempered high carbon spring steel strip wherein the specimen is held and bent across the grain in a vice-like calibrated testing machine. Pressure is applied until the metal fractures at which point a reading is taken and compared with a standard chart of brake limitations for various thickness ranges.

Bainite

แปลว่า(english) A eutectoid transformation product of ferrite and a fine dispersion of carbide, generally formed at temperatures below 840 to 930 F (450 to 500 C): upper bainite is an aggregate containing parallel lath-shape units of ferrite, produces the so-called feathery appearance in optical microscopy, and is formed at temperatures above about 660 F (350 C); lower bainite consists of individual plate-shape units and is formed at temperatures below about 660 F (350 C). Also, a slender, needle-like (acicular) microstructure appearing in spring steel strip characterized by toughness and greater ductility than tempered Martensite. Bainite is a decomposition product of Austenite best developed at interrupted holding temperatures below those forming fine pearlite and above those giving Martensite.
