  • TMAC 3.0
    Caron Engineering's Tool Monitoring Adaptive Control (TMAC) system monitors tools using sensors for power, vibration, or strain to measure tool wear in real-time to maximize tool life and prevent breakage....

  • Caron Engineering develops CNC machine optimization solutions that are essential for any Smart Factory.  They are excited to introduce their newest Tool Monitoring Adaptive Control system…TMAC 3.0. TMAC monitors tools using customized sensors for power, vibration, or strain to measure tool wear.  TMAC learns the cut, allowing the operator to visualize the actual cutting to make the necessary adjustments to run at optimum efficiency.

    By measuring tool wear in real-time, TMAC will automatically expire a tool if excessive wear is detected (and can signal a redundant tool) or immediately stop the machine and retract the tool in the event of breakage. This direct interface with the CNC control allows machines to run unattended.

    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. 

    TMAC can optimize almost any cutting operation but also mitigates specific manufacturing challenges with difficult to machine materials, such as hard aerospace components.  Typically, programmers must plan for the worst material condition, which leads to lengthy cycle times and accelerated tool wear.  This is especially true with aerospace components since they are machined from alloys and composite materials, and from either a casting or forging or single solid block of material.  TMAC Adaptive Control overrides the machine tool feedrate to automatically make adjustments based on the cutting power load of the tool.  Thus, TMAC is increasing the feedrate with low power cuts and decreasing with high power cuts and as tools wear.  By making real-time adaptive control feedrate adjustments TMAC optimizes the entire cutting process, extends tool life, and reduces cycle time up to 60%. 

    TMAC collects a large amount of data for analysis.  It utilizes a separate high-speed processor capable of quickly processing data from multiple different sensors including power, vibration, strain, coolant pressure, coolant flow, and spindle speed.  With multiple sensor options and high speed processing, TMAC can monitor the total health and condition of the machine. Users can overlay cutting data to compare cuts, interrogate alarms and events, access historical tool wear data, inspect CNC position data, and even analyze bearing health with the bearing analysis feature. All Caron Engineering products are MTConnect compliant allowing seamless communication with OEE software.

    Typical installation time for TMAC is one day or less. This can vary slightly depending on the number of sensor options and monitoring capacity the customer requires.  Standard training is two days to learn the system, though more can be added at the customer’s request.  There is also free online training for TMAC, which is also built into the software, so customers can have training and tutorials at their fingertips.  Customers often see a ROI within the first three months of implementing the system.

  • Caron Engineering’s latest version of ToolConnect is a more robust version of their tool identification and data transfer system. ToolConnect is a retrofit hardware and software package for machine tools that eliminates human error and reduces setup time by automating the transfer of CNC tool data to and from the control. 

    ToolConnect uses RFID tags, embedded in tool holders. Utilizing a tool presetter, the measurement data is written to the RFID tag. The tool is then placed in a custom RFID read station at the machine, and the data is read by ToolConnect. ToolConnect automatically updates tool offsets to the control. When machining is complete all tool life information is updated back to the RFID tag, which can be read anywhere. ToolConnect eliminates the need for a post processor.

    This latest version of ToolConnect has a new flexible design which is completely customizable. The system is built specifically to the customers’ requirements, from the (drag and drop) design of the UI to the overall process and functionality of the system. And with the new web-based interface, the UI can be displayed on any connected PC. 

    As an added benefit to the user, ToolConnect can now be programmed remotely. As the user requires more functionality from the system, new features can be added without waiting for an on-site service call.

  • Caron Engineering’s AutoComp software delivers error-free tool offset control. AutoComp is a Windows based software application that processes data from almost any electronic gauging device and updates the tool offsets automatically in the CNC control. All Caron Engineering products interface directly with most CNC controls to optimize machining.  AutoComp is doing just that by closing the loop for many manufacturing cells and eliminating costly data-entry errors at the same time. 

    So, how does it work? (1) The part is machined.  (2) The part is measured using almost any electronic gauging device (i.e. wireless calipers, laser micrometers, CMM’s, vision systems, etc.). (3) AutoComp reads the measurement file and compares the data to user programmed compensation limits to determine if compensation is required.  (4) AutoComp automatically adjusts tool offsets in the CNC control.

    During setup, the user creates an AutoComp routine consisting of the essential part dimensions and inputs the parameters (tolerances and compensation limits) for each dimension. AutoComp reads the measurement file and checks each measurement against the feature limits to calculate the correct amount to offset each tool.  AutoComp sends this information to the CNC control automatically, with no operator intervention required. 

    The built-in PartView feature allows the user to upload a (jpg) picture and visibly associate each area of the part being measured for deviation.  The operator can more easily identify which area of the part will be compensated. The measurement blocks are highlighted to clearly see at a glance if the part measurement is good (green), requires compensation (yellow), or is out of tolerance (red).

    AutoComp also has the ability to track tool wear and report when a tool change is needed.  Each time a tool is compensated, the amount of compensation is saved.  When tool compensation has exceeded a user-defined threshold, a wear limit is issued informing the operator that the tool needs to be changed. AutoComp can also signal the CNC control to automatically call a redundant tool or stop the machine. 

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

    AutoComp enables automatic tool wear compensation that maintains part accuracy and eliminates human error, thereby improving product quality and reducing scrap.
