Inspection Plus software for machining centres
Inspection Plus
About Inspection Plus
Inspection Plus provides an integrated package of macro software that includes vector and angle measure options, print options (controller dependent) and an extended range of cycles.
Inspection Plus includes an SPC cycle, 1-touch or 2-touch probing options, tool offset compensation by percentage of the measured error, and output of data stored into an accessible variable stack.
Features and benefits
Compared to the more basic Inspection software:
- All cycles in one integrated package
- Improve output data storage and report formatting
- Extra cycles - angle corner find, internal boss / web, vector probing, angled web / pocket measure and stock allowance
- Feature-to-feature distance measurement
- Optional 1- or 2-touch probing - one touch probing on controls with high speed skip, whilst two touch cycles offer greater accuracy where a high speed input is not available
- Protected positioning - stop the machine in the event of an unexpected collision
- Tolerances on size and position, applying an alarm if material is out of tolerance
- Ensure process stability by specifying a band around the nominal size where no error compensation is applied
- 'Damped' corrections (% of error feedback) to avoid overshooting the nominal size
- SPC feedback based on trend analysis and average readings
- Apply correction factors that take account of known process characteristics
- Results can be printed or written to a file

The accuracy of a probe measurement depends on the speed with which the machine tool control samples the probe output. If the sample rate is low, then probing moves must be slow to avoid measurement uncertainty.
1-touch cycles
On
machines fitted with high speed probe inputs (sample
time less than 1 ms), a 1-touch probing
cycle is the quickest way to get an accurate reading.
These simple cycles involve driving the probe stylus onto the surface in one rapid motion. The high speed input ensures a reliable indication of the surface position.
Renishaw 1 touch cycles include false trigger recovery.
2-touch cycles
On
machines fitted with standard probe inputs (sample time
more than 1 ms), a 2-touch probing
cycle is the quickest way to get an accurate reading.
These cycles involve driving the probe stylus to find the surface in one rapid motion. This gives an approximate location for the surface. The cycle automatically backs the stylus off the surface by a small distance, and then drives it back onto the surface at a slower speed. This second measurement move is used to take the accurate reading.
