(See: EMMA) MENDER: The acronym MENDER stands for: MEASURE - PHYSICAL ITEMS EVALUATE - RESULTS SCIENTIFICALLY NEEDS - IDENTIFY AND RECORD DEVELOP - ACTION PLAN EXPENSES - CONSIDERED AND APPROVED REPORTING – RESULTS MENDER is a predictive maintenance program that is designed to define a machine's condition and recommend the action required to correct any faults in order to reduce machine downtime for mechanical delays. METALURGICAL SAMPLE: A sample slug, part, or section of a carbonized, or hardened steel used for testing to determine structure, hardness, case depth, etc. MICROINCH: A unit of measurement for surface finish; measured in millionths of an inch. MICROMETER: Instrument used to measure various distances, angles, etc. MICROSTRUCTORE: The fine, internal structure of steel resulting from being heated to a critical temperature then quickly quenched. The microstructure, or how the parts that make up steel are arranged, controls how the bearing will perform. 微观组织结构:钢材被加热到临界温度以上然后迅速淬火形成的微观内部组织结构,微观组织结构或者说钢材内部组织是如何排列的将决定轴承的性能。 MIL: One thousandth of an inch. The Mil is commonly used to describe the thickness of thin items such as trash bag, The 1Mil is the one that won't get you to the street and the 2Mil is the heavy weight. MULTICHECK GAUGE: Gauge which has the capability of measuring more than one dimension of a piece of product. N 返回顶部 NEC: NATIONAL ELECTRIC CODE, the standards concerning anything to do with electrical work. NIB: Green roller defect on the small end radius; caused by taper die failure. A sharp protrusion on the small end of the roller. NITAL ETCH: Process of checking surfaces of ground product for cracks or burns by use of a series of acids and neutralizers. NOISE DOSIMETER: Instrument used to measure in decibels the amount of noise an employee is exposed to over an eight hour work day. NO GO: Indicates that an order for product has not been satisfied; the term may imply a rush on the order because the customer needs have not vet been met. NO STOCK: Surface of any piece of product which does not have enough stock to grind off in order to grind it to the correct size; usually visible as black, irregular area below abrasive contact. NO STOCK ID: Defect on inner diameter; large NCU condition indicating lack of stock for regrinding within specifications, machined undersize in green operation or caused by error in hardening process. NOT CLEANED UP: Defect found on any surface of a piece of product; the rib or other surface did not clean up adequately during the grinding operation. Also called no stock. (See: No Stock ) 不完全加工:零件任何一个表面的缺陷;挡边或其他表面磨削过程中没有完全完成工艺需要。 NOT TO MAN: Scrap produced by an operator which is not charged to him. NOT TO PRINT: Product or machinery which is not made to concur with blueprint specifications. NPM: New Product to Manufacture, is a system used for production. It replaced part number tooling data release (PNTDR) system. NPR: New Product Request; system to obtain management approval, feasibility to manufacture product and obtain price of the product. New product request must precede other systems, such as SPO, NPM and POR. O 返回顶部 ON TIME DELIVERY: A measure of pieces delivered to a customer within a given period vs. the expected pieces to be delivered. The customer can be internal or it can be the actual customer receiving the product. This is expressed as a percent and the actual method of determining delivery can vary by area. |
