Description
- 1. Field of the Invention
- The present invention generally relates to machine tools, and particularly to a desktop milling machine with an ovate-shaped bridge.
- 2. Description of the Related Art
- Micro-scale (and meso-scale) components have generally been produced by conventional machine tools. Since by definition micro components are small, the dimensional tolerance allowances would also be small, thereby creating a high incidence of error when utilizing conventional machine tools to manufacture the micro components. To alleviate these errors, relatively small computer numerical control (CNC) desktop milling machines have been employed to manufacture micro components. The use of these desktop milling machines has greatly reduced manufacturing errors in the production of micro components, saving both time and money. However, the high speed manufacturing techniques performed by the desktop machine produce high-frequency induced loads and temperature rises that can cause distorting resonances in the frame or bridge of the machine.
- The major problem that may result from the resonances is that the disturbance set up in the bridge is also easily transferable through relatively weak joints back onto the spindle and tool assembly, which are supported on the bridge, causing deformations. Although such deformations might be slight, they have a high impact on the accuracy of a micro-milling procedure. The effect of this on the already complex dynamics of the spindle-tool system may be enough to cause bad surface quality, chatter, and tool breakage.
- Hence, it is important that the bridge has higher natural frequencies and stiffness to resist these deformation resonances. A design that would produce a bridge that has a higher natural frequency than the related art bridges would alleviate the effect of the distorting resonances and would greatly enhance the efficiency of the desktop milling process. Thus, a desktop milling machine with an ovate-shaped bridge solving the aforementioned problems is desired.
- The desktop milling machine with an ovate-shaped bridge is a desktop milling machine of the computer numerical control (CNC) type having a bridge or frame structure designed to alleviate bridge deflections and deformations that are caused during the high-speed milling processes. In a preferred embodiment, the bridge is formed with an opening for receiving a work piece or micro-component therein during the milling process. The opening is of an ovate or egg-shaped configuration. A second embodiment provides an ovate contour in a vertical wall of the bridge. It has been determined that the ovate design of the bridge creates a structure that has a higher natural frequency than other milling machine bridges and greatly reduces the incidence of bridge-deforming resonances. The front face of the bridge structure supports the high-speed spindle and removable milling tools, as is conventional in the art.
- Accordingly, the invention presents a desktop milling machine that is configured to minimize manufacturing errors that may arise during the milling process. The milling machine is stable, rugged and dependable. The invention provides for improved elements thereof in an arrangement for the purposes described that are inexpensive, dependable and fully effective in accomplishing their intended purposes.
- These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
-
FIG. 1 is an environmental, perspective view of a first embodiment of a desktop milling machine with an ovate-shaped bridge according to the present invention. -
FIG. 2 is a perspective view of a first embodiment of the frame of a desktop milling machine with an ovate-shaped bridge according to the present invention. -
FIG. 3 is a perspective view of a second embodiment of the frame of a desktop milling machine with an ovate-shaped bridge according to the present invention. - Similar reference characters denote corresponding features consistently throughout the attached drawings.

Awork tool 16 is removably mounted to thehigh speed spindle 14. As is well known,spindle 14 is preferably selectively vertically adjustable and movable along a controlled axis by any suitable type of vertical mount or mechanism. Thework tool 16 may be one of many types, such as a grinder, polisher, drill, etc. Thebridge 12 comprises threesupport legs 18 that are preferably bolted to aplatform 20. Aworkpiece holder 22 is positioned on theplatform 20 and is movable thereon. A workpiece (micro component) 24 is removably clamped in the workpiece holder. Anopening 26 is cut out of thebridge 12, which provides space for manipulating theworkpiece holder 22 andworkpiece 24 in proper alignment with thetool 16 when performing a milling procedure. The opening 26 is defined by acontinuous wall 28 and has an ovate configuration. As pointed out above, this configuration has been determined to provide stability for the frame and minimize the effects of bridge deformation due to resonance forces produced when performing a milling procedure. As is well known in the art, theworkpiece holder 22 is preferably mounted on an X-Y table, allowing for two-dimensional horizontal adjustment of theworkpiece 24 with respect to the milling machine. - In the embodiment as shown in
FIG. 3 , thebridge 30 is L-shaped in profile, having a work-holding platform 32. Abridge wall 34 is mounted on theplatform 32 and rises vertically therefrom. A high-speed spindle 14 (shown in phantom lines) is mounted on the front face of thebridge wall 34. The rear wall, or rear face of thebridge wall 34, is of anovate configuration 36. As in the previous embodiment, high-speed spindle 14 is preferably selectively vertically adjustable and movable.
