The finish will be a result of the feeds and speeds of your cut and chosen method.

is so , then how can i shape the cutter that accurate ? i mean make a perfect half circule in the cutter ?
your help are much appricated |
The term "shaping machine" can have multiple definitions. If you have a single tooth cutter stroking shaper, there is still the need to hold and cut 1 meter in length. Not very realistic if the stroke of the shaper were shorter than 1 meter. In the States, we would call this a planer/shaper. I don't think they like ending a cut abruptly.
Some shaping machines are used to cut a profile into wood molding trim. These do use a rotary cutter similar to routers, but can be made up with stacked cutters to modify the shape as desired. It may be possible to cut aluminum in steps, but not all in one pass as wood is done. Lots of cutting oil would keep the chips from sticking to the cutter since these machines are very high RPM. The problems will be the ability to hold the part solid while feeding it through and then keeping the feed consistant to get a good finish. It can work with exreme care if only cutting the radius. If you need to cut the angle too, it should be done in seperate operations. From a safety stand point, I'd consider this as a last resort.
The radius being perpendicular to the angle forces a rotary cutter option to spin on the axis parallel to the angle plane or a ball nose cutter perpendicular to that plane. A single tooth cutting machine will need the part tilted to feed in one of the shapers axis into the radius center line.
If you have a local cutter grinder, it would be best to have any profile cutter custom made. A single tooth cutter can be hand ground and used in a fly cutter as has been mentioned in another post offering. It is just really slow!
