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 machining a bulb slot in a disc, the method comprising:
- roughing a slot in the disc;
- 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;
- semi-finishing the bulb form;
- and
- finishing the bulb form to form the bulb slot,
- wherein the step of roughing upper angle portions in the slot is performed via a first rougher tool that is fed through the disc along a first and second tool path, wherein a first of the upper angle portions is formed by the first rougher tool tilted in a first orientation via the first tool path and a second of the upper angle portions is formed portions is formed by the first rougher tool tiled in a second orientation via the second tool path.
A method of machining a bulb slot in a disc, the method comprising:
- roughing a slot in the disc;
- 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;
- semi-finishing the bulb form;
- and
- finishing the bulb form to form the bulb slot wherein,
- the step of roughing upper angle portions in the slot is performed via a first rougher tool that is fed through the disc along a first and second tool path, wherein a first of the upper 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 upper angle portions is formed via the second tool path where the first rougher tool is tilted in a second orientation;
- and
- the step of roughing lower angle portions in the slot is performed via the first rougher tool that is fed through the disc along a third and fourth tool path, wherein a first of the lower angle portions is formed via the third tool path where the first rougher tool is tilted in a third orientation and a second of the lower angle portions is formed via the fourth tool path where the first rougher tool is tilted in a fourth 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;
- semi-finishing the bulb form;
- and
- finishing the bulb form to form the bulb slot,
- wherein the step of roughing lower angle portions in the slot is performed via a first rougher tool that is fed through the disc along a first and second tool path, wherein a first of the lower angle portions is formed by the first rougher tool tiled in a first orientation via the first tool path and a second of the lower angle portions is formed by the first rougher tool tiled in a second orientation via the second tool path.
