OUTLINE FOR HURCO CONVERSATIONAL PROBING

PART PROBE

INSTALLATION:

Disassemble the MP700 probe body, set the appropriate dipswitches within the body per the Hurco drawing. The switches as a default from Renishaw are not to Hurco standards.

  • Refer to the supplied MP700 Renishaw manual for assembly instructions and location of switches.
  • Switch settings: SW1-1=off, SW1-2=off, SW1-3=on, SW1-4=off.
  • Switch settings: SW2-1=on, SW2-2=off, SW2-3=off, SW2-4=on.

Insert the MP700 probe assembly into the spindle. Indicate the Ruby stylus to obtain a maximum run out of .0002”. Adjust the 4 grub screws in the alignment plate to achieve run out. Refer to the supplied manual for detail.

Create the part probe tool as a dedicated tool within the machine’s tool library.

In the tool library select a tool number and create the description of the tool to be a Probe.

Set the dipswitches within the OMI unit per the Hurco drawing. Reference the Renishaw OMI manual for location and procedure to disassemble.

  • Mount the OMI interface within the machine enclosure. NOTE: the OMI must be able to receive a signal from the part probe at any position within the stroke of the machine tool.

PART PROBE PARAMETERS:

Part probe parameters are user definable to select the feedrate of the probe and the iterations of the probe deflections.

Parameters selectable in the part setup to allow for probe stylus diameters, and the working range of the probe within the machine limits

PART PROBE CALIBRATION:

Deflection offset routine needs to be performed at the initial installation of the probe system to maximize the accuracy of the probing hardware on the machine tool. These offsets will be utilized each time a probe deflection occurs.

Deflection offsets will need to repeat if a stylus change occurs to compensate for a change in the hardware.

Deflection offsets are best performed with a ring gage. The ring gage should be set on the machine’s table and swept in with an indicator to determine the true X and Y-axes center line of the gage to perform the offset routine.

PART PROBE CYCLES:

Six (6) standard canned cycles within the conversational software to perform part offset calibration in either manual or automatic cycles.

  • Edge
  • Hole
  • Cylinder
  • Rectangular Pocket
  • Rectangular Solid
  • Plane Intersection.

PART PROBE SKEW CYCLES:

Five (5) Skew cycles, within the conversational software to perform a skew offset for irregular shapes or non-square fixturing. Skew cycles can be performed in either manual or automatic cycles.

  • Edge
  • Hole
  • Cylinder
  • Rectangular Pocket
  • Rectangular Solid

PART PROBE INSPECTION CYCLES:

Six (6) Conversational data blocks insert able within the automatic program of the machine to inspect geometry while part are still fixtured upon the machine tool.

  • Inspection setup is relative to machine zero.

Inspection data stored within the machine’s hard drive relative to the name of the program.

Time and date stamped files.

  • Files are a continuation of data. And not overwritten.

TOOL PROBE

Hurco offers the tool probe option either as a TS27R touch tool probe or as the NC-1 Laser non-contact probe.

TOOL PROBE INSTALLATION:

Probes can be mounted anywhere on the table surface.

Probing can be performed in X or Y-axis.

Probe system must be accurately indicated true to the axes travel on the machine tool.

The NC1 laser probe must have the internal dipswitches set to the Hurco drawing. The switches as a default from Renishaw are not to Hurco standards.

  • Refer to the supplied NC1 Renishaw manual for assembly instructions and location of switches.
  • Switch settings: SW1=Off, SW2=On, SW3=On, SW4=Off.

PARAMETERS TS27R TOUCH PROBE:

Parameters are user definable to select the position of the hardware on the table surface.

Parameters are user definable to select probing federates and the iterations of the probe deflections.

Parameters selectable in the tool setup to allow for probe stylus diameters, and the working range of the probe within the machine limits

PARAMETERS NC1 LASER PROBE:

CALIBRATION:

Beam or deflection offset routines must be performed to maximize the accuracy of the probe hardware upon the machine tool.

Offsets are stored in memory.

Calibration and offsets will only need repeated if the probe is moved upon the machine tool or if a replacement is made.

A reference tool is needed to calibrate the probe system. If a part probe is resident upon the machine tool, then the part probe becomes the reference calibration tool.

TOOL SETUP PAGES:

TOOL PROBE CYCLES:

  • Tool probe cycles within the tool setup menu offer the ability to probe calibrate single tools or probe calibrate multiple tools selected within the machine’s tool library.
  • Tools can be probed for tool length, tool diameter, or length and diameter.
  • Tool probing can be performed with tools idle, oriented, or running at feedrate.
