Tool offset updates

Process control can be achieved with closed-loop feedback using Equator™ gauging data to update tool offsets directly on machine tool controls.

Real-time feedback

The gauging results can be easily read in real-time by a software package which offers the ability to connect to certain modern machine tool controls. This allows offset values to be updated, enabling true automated process control. Data from Equator can be used to update tool offsets repeatably and reliably, compensating for common causes of process instability, for example tool wear and thermal drift.

Maintain acceptable part tolerances

Tool offsets can be statistically controlled to maintain acceptable tolerances of machined parts. This is achieved by calculating tool compensation based upon a running average of feature measurements compared with tolerance limits.

Report need for tool change to the operator

When a tool has been compensated more than a user defined threshold, a wear-limit warning is issued, informing the operator that the tool needs to be changed. A signal can also be sent to the CNC control so that a sister tool can be called automatically or the machine can be stopped before the next cycle.

Record historical tool wear data

All measurement and compensation data is saved to a file. The data is date and time stamped for later analysis. The operator also receives real-time status of the remaining useful life for each tool.
