英文工程图纸的右下边是标题栏(相当于我们的标题栏和部分技术要求),其中有图纸名称(TILE)设计者(DRAWN)审查者(CHECKED)材料(MATERIAL)日期(DATE)比例(SCALE)热处理(HEAT TREATMENT)和其它一些要求,如:
1)TOLERANCES UNLESS OTHERWISE SPECIFIAL 未注公差
2)DIMS IN mm UNLESS STATED 如不做特殊要求以毫米为单位
3)ANGULAR TOLERANCE±1° 角度公差±1°
4)DIMS TOLERANCE±0.1 未注尺寸公差±0.1
5)SURFACE FINISH 3.2 UNLESS STATED 未注粗糙度3.2
