Tool Monitoring System for Machining

TMAC CNC Tool Monitoring_Caron Engineering

Tool monitoring for CNC machining is essential for protecting the machine, maximizing tool life, and reducing cycle time. Caron Engineering's adaptive tool monitoring system, TMAC 3.0, is a real-time tool wear and breakage detection system, with adaptive feed-rate control capability. TMAC interfaces directly with the CNC control and uses high precision sensor technology to optimize machining and make real-time corrective adjustments through material cutting. The data collected by the TMAC adaptive tool monitoring system gives detailed insights to optimize cutting programs, to immediately increase performance.

TMAC will help you meet the demands of today’s competitive manufacturing environment.

Optimize Machine Tool Cutting

Caron Engineering's TMAC system uses high-precision sensors, a dedicated high-speed data processor, and intuitive HMI to measure tool wear and give real-time control over your cutting operations. By using the learned cutting data and defining thresholds, TMAC will calculate tool wear during cutting and automatically expire a tool when excessive wear is detected or issue a signal within 5 msecs to stop the machine and retract the tool in the event of breakage. 

By accurately monitoring tool wear in real-time you can prevent unplanned equipment downtime and stop potentially catastrophic events in their tracks. 

This real-time control is ideal for achieving lighter and unattended operations.



Optimize your cutting programs, maximize too life, and reduce cycle time with Caron Engineering's TMAC (Tool Monitoring Adaptive Control) System for CNC Machining!

 Tool Wear and Breakage Detection

TMAC calculates power over time or work of the cutting tool as a more accurate measurement of how the tool is wearing over time

TMAC measures tool wear and detects breakage by monitoring true spindle motor power. TMAC learns the optimum power for each tool and cutting section, and compares it to the user defined limits to calculate wear as the tool is cutting. It operates on the principle that the power required to cut a part increases as the tool’s cutting edges deteriorate

  • Monitors and reacts to tool wear in real-time
  • Uses multi-range sensors with auto-scaling display sensitivity
  • Prevents tool breakage and lowers scrap rate
  • Reduces the cost of consumable tooling
  • Provides valuable information about the cutting process
  • Stops the machine instantly in the event of tool breakage
  • Shows real-time data graphing as the tools are cutting

Sensor compatibility for tool wear monitoring: power, vibration, strain
Other monitored sensors include: coolant flow, coolant pressure, spindle speed

 Adaptive Control Feed Rate Optimization

CNC machines are typically programmed for the safest feed rates to accommodate the worst machining and material conditions.

TMAC adaptive control learns the optimum power for each tool and continuously maintains a constant tool load by automatically adjusting the feed rate in real-time.  TMAC increases the feed rate through low power cuts and decreases the feed rate through high power cuts and as tools wear. No operator intervention required!

The result? Decreased cycle time, longer cutter life, and more machine uptime, especially with difficult to machine materials.

See how adaptive control technology works to automatically optimize feeds and speeds during cutting!

Adaptive Control TMAC
  • Typical cycle time savings of 20 – 60%
  • Allows tools to run at optimum feed rates
  • Adjusts to variations in material, tooling, and depth of cut
  • Excellent for unattended/lights-out operation
  • Adjusts feed rates smoothly versus CAD/CAM programs that can only adjust per line in the program
  • Calculates tooth pass frequency to adapt to low RPM cutters

Sensors and Components

TMAC uses a dedicated high-speed data processor and has multiple integrated sensor options for total machine condition monitoring.

  • TMAC multi-range power transducers to measure the power load on the tool to determine wear
  • In addition to power, vibration and strain sensors can also be used to measure tool wear
  • Other peripheral sensors can be installed and monitored by TMAC including spindle speed, coolant flow, and coolant pressure
  • GE P11TF12 Compliant

System Features

The new TMAC 3.0 offers an intuitive user interface designed to handle the complexity of the software while providing simplicity for the user.  The web-based UI has completely customizable user views with a dynamic display that can be accessed from any device (including smart phones) and allows monitoring multiple processes and even multiple machine channels simultaneously. 


Multiple sensor channels can be monitored simultaneously!TMAC 4 Views screenshot

For instance, you can monitor power, vibration and coolant for a specific tool and section at the same time, and have unique limits for each sensor and channel.

  • Create multiple custom views to look at monitoring data in different ways
  • View up to 4 monitoring channels in a single view
  • Toggle between custom views with the touch of a button
  • Change background color to easily identify TMAC system

What Else Can TMAC Do?

TMAC Bearing Analysis screenshot

Bearing Analysis

A vibration sensor can be attached to the spindle, hardwired to TMAC, with the bearing analysis initiated in the CNC part program.

Signature Analysis

Using the signature analysis mode, TMAC learns the entire path (signature) of a cut using any sensor type

Data Analysis

TMAC saves and records all cutting data. This data allows the user to interrogate specific areas of the cut to look at anomalies in the normal cutting operation. If a tool uses inconsistent power over the same cut, the user can overlay these cuts to see what is causing any anomaly. This information can also give TMAC users insight into tool life comparison between different tooling vendors and regrinds.

TMAC Data Viewer

  • All monitored data and events are stored and can be exported in various formats for analysis
  • Data files can be opened simultaneously to view graphical differences
  • Cutting data files can be overlaid to compare cuts
  • CNC position data allows the user to inspect the CNC axis positions, program line number, and spindle RPM to interrogate alarms and anomalies at any point in the cut

TMAC Event Viewer
