Automatic tool calibration using user editable table

Multiple tables (programs) can be created for quick setup of repeat projects.
Tables can be generated by CAM system as a commented setup sheet.
Identify excessive runout, worn, or misloaded tools.
Ideal for machines that do not have an integrated calibration feature.
Uses Renishaw tool setter (OTS).

Options for error checking include...

Length tolerance, confirm tool extension for best performance and collision avoidance.
Diameter tolerance, verify the correct tool is mounted properly.

Value entered into the table determines calibration option...

“Negative tool diameter” e.g. -0.75 calls length setting.
“Tool diameter” e.g. 0.75 calls length and diameter setting.
“0.0” calls C/L length setting.
“#0” skips this tool.

Sample…

#1=-0.75 (LENGTH ONLY)
#2=0.75 (LENGTH AND DIAMETER)
#3=0.0 (C/L LENGTH ONLY)
#4=#0 (SKIP THIS TOOL)

Complete validation and calibration of Renishaw tool setter (OTS) and spindle inspection probe (OMP)

Validate, measure, and report if adjustments are required.
Concentricity of “tool calibration gage”
Planar status of “tool calibrator stylus”
Concentricity of “spindle probe stylus”
Calibrate and optimize.
Insure both “tool” and “spindle” probes are calibrated and optimized together for seamless performance.
Insures capability of your equipment, reducing scrap and rework.
Generate date stamped reports for historical charting.
