Look at careers in metaiworking
Nearly every product of modern industry either contain metal parts or is produced on a mathine that is made of metai parts. Many of these parts require machining and must be madeby workers skilled in machine tool processing. A major portion of the labor force in Americia is employed directly or indirectly in metalworking occupation. Of all of the occupatin groups classified under metalworking, the machining occupations employ the largest number of workers. In 1974, more and one million works were employed in machining occupation. An estimated 350,000 were employed as machinists and instrument makers; 170,000 as tool and die markers;50,000 as setup workers and layout artists; and 600,000as maching tool operstors.

看看职业metaiworking
几乎每一个产品的现代工业也含有金属零件或正在生产的mathine这是用金属零件。许多这些地方需要加工的，必须madeby工人熟练掌握机床加工。大部分劳动力就业在Americia直接或间接在金工占领。所有occupatin集团归入金属加工，机械加工行业雇用人数最多的工人。 1974年，更多的100万工程受雇于加工占领。据估计，被聘为三十五点○万机械师和工具制造商;一十七点○万作为工具和模具标记; 50000作为安装工人和布局艺术家;和600000as机床operstors 。

铸件，锻件， barstock ，厚板，和冲压件。许多高产量的部分是对专门aitomatic生产设备。一旦建立了一个熟练的安装工，这些机器只需要一个不熟练运营商在很多规模小于50 。这requres的服务，高度熟练的机床操作员，机械师，以及工具和模具制造商。
熟练的机械加工工人必须能够阅读工作图纸次测量仪器巧妙。在做工精度的要求是因为许多金属部件必须机公差在正负必须以加工公差在正负0.0025毫米（ 0.0001 〃 ） 。一些高技能toolmakers作出特殊精密测量仪模块和其他专门的测量工具，是准确的，以正负0.000058毫米[ 0.000002 〃 （ twe micronches ） ] 。
学习Appreticeship
一个共同的方法，进入了一个熟练的金属加工服务的职业生涯是通过学徒。学徒期是正式的，对在职培训期间，工人学习的各个方面的选定贸易。机械师学徒学习蓝图阅读，数学铺，机床操作和科学有关的贸易。学徒也学习其他有关技术资料或基本成为一个有效的工作者。
