Abstract
A machine tool display device provides a continuous real time display of a machine tool load as a function of position of a tool relative to a work surface being machined. Position is displayed on a first axis and load is displayed on a second axis perpendicular to the first axis. A mirror image of the display may be provided about a third axis perpendicular to the first axis so that a cross sectional representation of the working surface is displayed. The machine tool includes means for manual or automatic adjustment of the position of the tool relative to the work surface in order to achieve a predetermined final work surface profile.

A display device configured for a machine having a tool which removes material from a work surface having an axial length, where an axial position of the tool relative to the work surface varies, the machine including a load sensor for sensing a load on the machine as material is removed from the work surface and a position sensor for sensing the axial position of the tool, said display device comprising:
- visual output device, and
- a display driver connected to said visual output device so that said visual output device provides a continuous display of the load as a function of the axial position.
A display device configured for use on a machine having a tool which engages a work surface and removes material therefrom, where the axial position of the tool relative to the work surface varies, the machine including a load sensor for sensing load on the machine as material is removed from the work surface and a position sensor for sensing axial position of the tool, said display device comprising:
- a visual output device;
- and
- a display driver operatively connected to said visual output device so that, during a machining operation, said visual output device displays the machine load verses the tool position for a plurality of tool positions to provide a representation of the profile of the work surface.
A machine for removing material from a work surface, the work surface having an axial length, said machine comprising:
- a tool for engaging the work surface and removing material therefrom, an axial position of said tool relative to the work surface varying,
- a load sensor for sensing a load on the machine,
- a position sensor for sensing the axial position of said tool,
- a visual output device,
- a display driver connected to said visual output device so that said visual output device provides a continuous display of the load verses the axial position.
A method of displaying a load of a machine having a tool which engages a work surface removing material therefrom, the work surface having an axial length, the machine including a motor, said method comprising the steps of:
- sensing the load,
- sensing the axial position of the tool,
- continuously displaying the load as a function of the axial position of the tool on a visual output device.
A method of honing a bore in a workpiece, the bore including an axial length, said method comprising the steps of:
- axially stroking and rotating a honing tool within the bore, said honing tool engaging an interior surface of the bore, removing material from said interior surface,
- sensing a load of the honing machine while said honing tool engages said interior surface,
- sensing an axial position of said honing tool relative to said bore axial length while said honing tool engages said interior surface, and
- continuously displaying a profile of the bore during the honing operation.
A machine for removing material from a work surface, the work surface having an axial length, said machine comprising a tool for engaging the work surface and removing material therefrom, an axial position of said tool relative to the work surface varying as the material is removed, load sensing means for sensing a load on said machine as the material is removed, position sensing means for sensing an axial position of said tool relative to the work surface, means for coordinating a sensed load with a corresponding sensed position, and means for displaying a plurality of sensed loads, each sensed load displayed relative to its corresponding sensed position and in an orientation which provides a representation of the profile of the work surface.
