Modern manufacturing demands speed, accuracy, consistency, and confidence. In our recent webinar, Ryan Mermall, Sales Engineer at Mastercam, was joined by Lilian Barraud, President of BLUM-Novotest USA, to explore how CNC probing powered by BLUM hardware and fully integrated with Mastercam Probing, helps shops streamline setups, reduce risk, and unlock smarter automation.
Here is a recap of the key takeaways from the webinar, and why probing is quickly becoming a must-have for forward-thinking manufacturers.
Why CNC Probing Matters More Than Ever
At its core, CNC probing gives machinists real-time visibility into what is happening inside the machine. Instead of relying on assumptions or manual checks, probing measures actual part and tool conditions directly on the machine, enabling:
- Increased accuracy and repeatability
- Reduced setup and cycle times
- Improved part quality and first time-right results
- Greater process stability even with thermal drift or long runtimes
- Data collection for traceability, SPC, and continuous improvement
As Lilian explained, probing is often the first step toward automation, helping shops build reliable, repeatable processes that reduce dependency on manual intervention.
Inside BLUM: Probing Built for the Machine Tool Environment
BLUM-Novotest brings decades of machine-tool-focused engineering to CNC measurement. Founded in Germany in the late 1960s and operating in the U.S. since 1997, BLUM designs probing solutions specifically for the realities of the shop floor: coolant, vibration, temperature changes, and high-speed motion.
What Makes BLUM Probes Different?
- High-speed probing with minimal cycle-time impact
- Optoelectronic measuring mechanisms (not mechanical switches) for long-term accuracy and durability
- Non-lobbing, rotation-symmetric design for consistent results in any probing direction
- Coolant-on probing with IP68-rated protection
BLUM also offers specialty probes for advanced applications, including contour scanning and in-process surface roughness measurement. These capabilities are typically difficult or impractical to achieve with offline inspection.
Mastercam Probing: Fully Integrated, Fully Practical
While hardware is essential, real power comes from how it is used. That is where Mastercam Probing shines.
Mastercam Probing is a fully integrated add-on that allows probing routines to be programmed just like any other toolpath directly inside the Mastercam environment. No manual coding, no custom workarounds, and no guesswork.
What This Means for Programmers
- Probing operations are associative to geometry
- Full support for backplot, Verify, and Machine Simulation
- Reduced risk of manual programming errors
- One consistent workflow across multiple machine brands and controls
Instead of treating probing as a separate task, Mastercam makes it a natural part of the programming process.
Probing Before, During, and After Machining
A key theme of the webinar was how probing fits throughout the entire machining lifecycle:
Before Machining
- Automatically set work offsets
- Align parts and compensate for misalignment
- Verify material size and presence, which is ideal for lights-out or automated loading
During Machining
- Check tool length, wear, and breakage
- Perform in-process inspection
- Use conditional logic (if/then) to automatically recut, adjust offsets, or stop the machine
After Machining
- Inspect critical features while the part is still clamped
- Capture measurement data for reports and quality documentation
- Reduce scrap before parts ever leave the machine
This approach minimizes surprises and maximizes confidence, especially on complex or high-value parts.
New in Mastercam 2026.R2: BLUM Laser Tool Center Support
One of the most exciting updates discussed in the webinar is new support for BLUM’s Digital LC laser tool measurement systems in Mastercam 2026.R2.
Unlike traditional laser systems that capture a single measurement, BLUM’s digital technology combines analog and digital data, collecting thousands of data points as the tool passes through the beam.
What Shops Can Do with Digital Laser Measurement
- Measure tool length, radius, wear, and breakage
- Scan tool contours, including ball and corner radii
- Optimize tool offsets based on actual cutting conditions
- Detect vibration and spindle health issues before cutting
All of this data integrates seamlessly into the Mastercam Probing workflow, bringing advanced tool insight directly into the program.
Turning Measurement Data into Actionable Insight
Probing does not just measure, it informs decisions. With Mastercam Probing and Probing Inspect, shops can:
- Store measurement results in user-defined variables
- Output data via DPRINT or network connections
- Generate visual inspection results inside Mastercam
- Create PDF inspection reports for documentation and traceability
This closes the loop between machining and quality, turning measurement into a powerful feedback system.
Final Thoughts: A Smarter Way to Machine
As the webinar made clear, many shops already have probes installed but aren’t using them to their full potential. By pairing BLUM’s advanced probing hardware with Mastercam’s integrated probing software, manufacturers can:
- Reduce setup time
- Improve part quality
- Enable automation
- Make better, data-driven decisions
Whether you are just getting started with probing or looking to expand its role in your process, Mastercam Probing helps you probe with confidence and machine smarter every step of the way.
