One embodiment of the invention has an inner hub attached to the rotating part of the machine tool and the slanted vanes attach to this inner hub and extend outwardly from it.

Aspects of the present swarf removal invention reside in various constructions and arrangements and parts and uses of the disclosed embodiments.

In embodiments of the vanes, they are composed of a wide variety of metallic or non-metallic materials, and the only requirement of the chosen material is whether it gives the vanes the required stability during high speed rotation so they don't significantly bend while creating the required air force on the workpiece.

Among the many different possibilities contemplated, the swarf removal invention also connects the slanted vanes to an outer shroud surrounding the machine tool swarf removal apparatus, and this arrangement also gives the slanted vanes the required stability during high speed rotation to create the required air force on the workpiece, during the operation of the machine tool. Another embodiment of the machine tool swarf removal apparatus is designing the apparatus as a one-piece component, such as a molded part.

Still another embodiment is to cut grooves into the inner hub, fit O-rings into these grooves, and thus provide one way to firmly and securely attach the machine tool swarf removal apparatus to the rotating part of the machine tool. Other embodiments include inserting, gluing, or molding an elastomer insert into the inner hub instead of using O-rings; this would also increase the adhesion between the rotating machine tool part and the apparatus.

Another embodiment of the invention is having the rotating part be the tool holder. Still another embodiment is designing the slanted vanes as part of the tool holder and thus reduce eliminate the need to maximize the adhesion between the tool holder and a separate apparatus.

A further embodiment is choosing the endmill as the rotating part, and yet another embodiment choosing the rotating portion of the spindle as the rotating part. Another embodiment attaches the slanted vanes to rigid inner hub. The inner bore of this inner hub is lined with an elastomer insert, providing increased adhesion between the rigid inner hub and the rotating part of the machine tool.

Among the many possibilities contemplated in the design and use of the machine tool swarf removal apparatus is having it operate in low-pressure coolant system, directing the vanes at the cutting area, and thus diverting coolant to that cutting area. In further embodiments of the invention the vanes attach to an inner hub, and this inner hub forms an interference fit between the inner bore of the hub and the outer diameter of the rotating tool part.

Also, another refinement of the invention is connecting the inner hub to the machine's tool holder. Various other objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of embodiments of the invention, along with the accompanying drawings. However, the drawings are illustrative only and numerous other embodiments are described below. Additionally, the scope of the invention, illustrated and described herein, is only limited by the scope of the appended claims.

Various embodiments of the invention are disclosed in the following detailed description and accompanying drawings. The following is a detailed description of exemplary embodiments to illustrate the principles of the invention. The embodiments are provided to illustrate aspects of the invention, but the invention is not limited to any one embodiment. The scope of the invention encompasses numerous alternatives, modifications and equivalents; it is limited only by the claims.

The details set forth in this description give a thorough understanding of the invention and for the purpose of clarity, the technical details of machine tools, known by one of ordinary skill in this technical field, are not described in detail so that the invention is not unnecessarily obscured.

The disclosed embodiments of the machine tool swarf removal apparatus operates in all types of machine tools with live tooling or rotating cutting tools. Additionally, the disclosed embodiments of the swarf removal apparatus work equally well in enclosed or open CNC machines. The embodiments of the machine tool swarf removal apparatus will work when attached to any spinning parts of a machine tool, when that spinning part is directed at the workpiece, and provides enough air pressure on the workpiece to clear keep it of the unwanted swarf during the operation of the machine.

A motor is enclosed within the top of the machine 8 , among other things, provides the force to rotate parts of the spindle 2. The spindle 2 connects the tool holder 4 to it with a tight and secure fit, and tool holder 4 holds the cutting tool 5 , also with a tight and secure fit.

Thus, the spindle 2 , tool holder 4 , and cutting tool 5 are securely connected and operate as one unit, rotating over and into the workpiece 7. As with the other parts of the machine tool, there are a variety of tool holder designs to hold different tools at different distances from the bottom of the spindle in different ways.

Any of these tool holders would be sufficient for the practice of the swarf removal apparatus as long as the swarf removal apparatus has a secure attachment to the tool holder and, as noted, during rotation creates enough force of air on the workpiece to clear it of unwanted swarf.

Additionally, embodiments could have a stationary table and only the cutting tool 5 would move, or both the table and cutting tool 5 could move in concert. But none of these details of different machine tools, like the angle of the cutting tool over the workpiece, or the movements of the table and cutting tool, have any impact on the novel and unique embodiments of the swarf removal apparatus disclosed herein. The spindle 2 , tool holder 4 , and cutting tool 5 of FIG. As noted, the spindle 2 , tool holder 4 , and cutting tool 5 rotate and maneuver to make the required cuts into the workpiece 7 , with whatever other parts of the machine tool are involved, like movement of table in concert with the rotating cutting tool 5.

Sweep lead out defines the sweep angle between the linear segment component of the lead out movement and the toolpath. You need to enable Explicit lead out in order to specify a separate lead out sweep angle. Otherwise, the same angle will be used for lead-in and lead-out.

Linear lead distance. Linear lead out distance. You need to enable Explicit lead out in order to specify a separate linear lead out distance. Otherwise, the same distance will be used for lead-in and lead-out. Keep down distance. The Keep down distance defines a length below which retracts are avoided. This means that lead-in and lead-out moves are still generated below this length, but the tool is only lifted up slightly.

Max transition distance. Use the parameter Max transition distance to define a maximum allowed length for transitions between cutting passes. If the distance between two passes is greater than the Max transition distance, the tool retracts or is lifted up and a lead-out and lead-in are generated.

Tolerance defines the maximum value the toolpath is allowed to deviate from the surface of the input geometry. A small tolerance value yields more precise toolpaths at the expense of longer computation times.

Stock to leave. Stock to leave defines the stock to leave in the plane perpendicular to the tool direction by offsetting the tool away from walls. Axial stock to leave. Axial stock to leave defines the stock to leave in the Z-direction, i. Axial stock to leave lifts the tool up from the surface by the specified distance.

Other side. Other side defines that the tool should machine the surface from other side. When looking from the top, by default the left side from the bottom contour is used.

Cutting mode. Creates passes using a defined stepdown from bottom curve. Passes near the top might follow the top curve if the distance between the bottom and top curve are not the same along the surface.

Creates passes using a defined stepdown from top curve. Passes near the bottom might follow the bottom curve if the distance between the bottom and top curve are not the same along the surface. Creates passes using a defined stepdown from the bottom curve.

Passes near the top curve might get trimmed if the distance between the bottom and top curve are not the same along the surface. Passes near the bottom curve might get trimmed if the distance between the bottom and top curve aee not the same along the surface. Creates morphing passes between bottom and top curves. Distance does not exceed provided stepdown but might be smaller in some places. Maximum stepdown. Maximum stepdown defines the maximum distance between cutting passes in the direction of the tool axis.

Tool offset. Tool offset defines additional depth relative to the bottom curve. Use positive value to move along tool axis and negative to move in opposite direction.

Pass overlap. Pass overlap defines an additional distance to move along the cutting pass before lead-out. Repeat pass. Fan distance. Maximum tool axis sweep. Maximum segment length. Click the Add Add all.
