Normal machine alignment is adequate for most work, but if the work is exceptionally large or requires extreme accuracy, shims may be employed to improve machine alignment. For accurate setups you should have and know how to use a dial indicator. Often, more time will be spent making fixtures to hold work than doing the actual machining.
Milling Machine Operations TheEngineersPost Page 5 The profile milling is the operation of reproduction an outline of a template or complex shape of a master dies on a workpiece. Different cutters are used for profile milling. An end mill is one of the widely used milling
Alignment of the mill head to the worktable is an important step of setup for the manual mill. A cylindrical metal fastener that secures a workpiece or workholding device into position. Alignment pins inserted in a worktable's T-slots can securely hold a vise. A nonferrous, silvery, lightweight, soft, very ductile metal.
