Abstract
A slot milling sequence includes a plurality of material removal processes or operations. Each of the material removal operations includes utilization of an end mill tool. Some of the material removal operations utilize trochoidal tool paths, whereas other material removal processes utilize one or more profile cuts. Some material removal operations that utilize profile cuts remove material from both sides of the cut in a single pass, whereas other material removal operations remove material from one side of the cut via a first pass of the end mill tool and remove material from the opposing side of the cut via a second pass of the end mill tool.
Claims19
A method of roughing a bulb slot in a work piece, the method comprising:
- roughing a slot in the work piece;
- roughing upper angle portions in the slot with a first rougher tool fed through the work piece along a first tool path tilted in a first orientation and along a second tool path tilted in a second orientation;
- roughing lower angle portions in the slot;
- roughing a bulb form in the upper angle portions and the lower angle portions of the slot.
A method of machining a bulb slot in a work piece, the method comprising:
- roughing a slot in the work piece;
- roughing upper angle portions in the slot;
- roughing lower angle portions in the slot;
- roughing a bulb form in the upper angle portions and the lower angle portions of the slot;
- wherein,
- the step of roughing lower angle portions in the slot is performed via a first rougher tool that is fed through the work piece along a first lower and second lower tool path, wherein a first of the lower angle portions is formed via the first tool path where the first rougher tool is tilted in a first orientation and a second of the lower angle portions is formed via the second tool path where the first rougher tool is tilted in a second orientation.
