Modern CNC machine shops face relentless pressure to boost productivity, shorten cycle times, and reduce costs — all while preserving tool life, part quality and process reliability. They must meet tighter delivery deadlines amid global competition. High-efficiency milling techniques can reduce roughing cycle times by as much as 80%, but often only for certain part features, limiting their overall impact. The challenge remains: how can manufacturers dramatically accelerate machining across varied geometries without chewing through cutting tools or risking process stability?
SolidCAM’s iMachining Toolpath & Wizard were designed to answer this challenge. According to Dr. Emil Somekh, founder and CEO of SolidCAM, the software’s intelligent toolpath strategy can reduce total CNC cycle times by 70% or more while also delivering dramatically longer tool life. In other words, iMachining lets CNC programmers push machining speeds to new heights without the usual drawbacks of excessive tool wear or breakage.

How iMachining Works: Constant Chip Load and Intelligent Wizardry
At the core of iMachining is a simple principle: maintain a constant chip thickness on the cutting tool. By keeping the cutter’s mechanical load consistent, iMachining avoids the stress spikes and vibrations that occur when cutting conditions suddenly change (for example, when a tool hits a pocket corner). Instead of using conservative, one-size-fits-all parameters, iMachining dynamically adapts to the cut in real time. Key components of this system include:
- Adaptive toolpath algorithm: A patented motion control algorithm continuously varies the tool’s radial engagement angle (within about 10° to 80°) and feed rate to sustain a constant chip thickness. This constant-load strategy prevents the force surges that cause chatter or tool breakage, enabling deeper and faster cuts even in tough materials without overloading the tool. Whenever geometry allows, the toolpath morphs into a smooth spiral that keeps the cutter engaged in material nearly 100% of the time, inserting trochoidal loops around corners or islands as needed to maintain optimal load conditions. The result is a highly efficient path with minimal air-cutting or sudden direction changes.
- Technology Wizard automation: The iMachining Technology Wizard automatically calculates optimal cutting parameters for each job. The programmer inputs the workpiece material, tool type and CNC machine specifications, and the Wizard outputs the ideal feeds, speeds, depth of cut and cutting angle to use. It factors in material machinability and machine tool limitations (spindle power, maximum RPM, etc.) to ensure the toolpath stays within safe limits. By taking the guesswork out of feed and speed selection, the Wizard ensures every iMachining toolpath is tuned to achieve maximum performance on that specific machine and tooling setup.
Notably, iMachining is available in both 2D and 3D modules — the former for roughing and finishing prismatic 2.5D features, and the latter for roughing complex 3D surfaces, enabling high-efficiency machining across a wide range of part geometries.
Unmatched efficiency: iMachining 3D automatically creates toolpath to maintain constant scallop height no matter the part complexity.
Key Benefits: Rapid Machining and Extended Tool Life
The most immediate payoff from iMachining is significantly shorter cycle times on existing CNC equipment. Many users report overall machining time reductions on the order of 50–70% and even more on hard metals, after switching to iMachining, even on complex parts. That kind of time savings means a job that once took all day might be finished by lunchtime, dramatically boosting the machine’s metal removal rate (MRR) in the process. Consequently, each machine can produce substantially more parts per shift than before. In short, iMachining frees up valuable machine capacity by completing work much faster than conventional methods.
Equally important, these aggressive machining strategies do not come at the expense of tool life. On the contrary, the constant chip load and smooth toolpath reduce wear on cutting tools. iMachining’s controlled, no-surprise cutting conditions prevent the abrupt force spikes that chip cutting edges and shorten tool life.
Additionally, the software often utilizes the full length of the cutter’s flute rather than just the tip, distributing wear more evenly along the tool. By avoiding excessive heat and stress on any one part of the tool, iMachining dramatically extends tool longevity. In fact, shops have seen their tools last several times longer — often 2x to 5x — even while running at much higher speeds and feeds than previously possible. Fewer tool changeovers and replacements further boost effective productivity and cost savings.
iMachining uses a tool’s full flute length to maximize tool life and MRR.
From Shop Floor to Bottom Line: Business Outcomes
Beyond the immediate machining improvements, iMachining delivers broader business benefits for manufacturers:
- Higher productivity: Drastically shorter cycle times let each machine produce more parts in a given period (for example, per shift), increasing output without additional equipment or labor. By accomplishing more work per shift, a shop can reduce backlogs and improve overall throughput.
- Increased profitability and ROI: Cutting parts faster lowers the machining cost per piece and allows for greater output, which directly improves profit margins. Many companies find that the investment in iMachining pays for itself quickly through these efficiency gains. Reducing tool consumption and scrap adds even more to the bottom line, accelerating the return on investment for this technology.
- Capacity improvements: By freeing up significant machine hours, iMachining effectively expands a shop’s capacity. This extra capacity can be used to take on additional customer orders or new projects without needing to buy more CNC machines.
- Faster delivery and responsiveness: Shorter machining cycles also mean shorter lead times for customers. Quicker turnaround boosts customer satisfaction and provides a competitive edge when deadlines are tight. With machines no longer tied up for long stretches, a shop can respond more flexibly to rush orders or changes in demand. In competitive bidding situations, the ability to deliver parts faster (and potentially at lower cost) can help win more business as well. Overall, iMachining gives manufacturers greater flexibility to scale up output and respond to customer needs.

Real-World Results: iMachining in Action
The performance claims of iMachining are backed by real-world results. For example, one manufacturer in the energy sector machining a notoriously difficult nickel-based alloy (Inconel) reported a staggering 86% reduction in cycle time for a particular part after implementing iMachining, along with a 500% increase in tool life on that job. Such dramatic improvements were in line with what the company observed on other components after adopting iMachining, proving that these gains are repeatable and not just an isolated case. Even previously skeptical users have become believers — as one shop owner put it, the promised 70–80% time savings with iMachining “are really true” when seen in practice.
Conclusion: Unlocking Productivity with Intelligent CAM
In today’s increasingly competitive manufacturing landscape, achieving more with existing resources is key. SolidCAM’s iMachining Toolpath & Wizard combines advanced, physics-driven toolpath control with tangible shop-floor benefits in speed and tool longevity.
