This year, we have contacted many foreign customers consulting about purchasing CNC gasket cutting machines, and a common topic in their needs is: whether the machine is equipped with nesting software. It is evident that automatic nesting software has increasingly become an important configuration in CNC oscillating knife cutting machines.
The gasket nesting software paired with Trustercnc’s CNC gasket cutting machine has an intuitive and easy-to-operate interface, making it simple to get started. You only need to enter different parameters in the input box, and the software system will complete the operation through intelligent automatic nesting— the entire process takes only a few minutes. According to feedback from our customers’ actual production and cutting tests: the “nesting in holes” function of the gasket nesting software can save their enterprises at least 30% in material costs.
Why Is It Recommended to Equip CNC Oscillating Knife Gasket Cutting Machines with Nesting Software?
Material costs often account for more than 60% of the total production cost. If nesting is unreasonable, it will cause a lot of plate waste. This is especially important for expensive materials, as it directly affects enterprise profits.
High Proportion of Material Costs in Gasket Production
Raw materials used in the sealing industry are often very expensive. Whether it is polytetrafluoroethylene (PTFE), high-end non-asbestos boards, or special Viton rubber, material costs usually account for 60% to 80% of the total production cost of gaskets. Even a 3% increase in utilization rate of these expensive plates can save enterprises a significant amount of costs every year.
According to statistics from the Society of Manufacturing Engineers (SME) and manufacturing research institutions, in the plate cutting industry: optimized nesting can increase material utilization rate by 10%–30%, thereby significantly reducing manufacturing costs.

Low Efficiency of Traditional Manual Nesting
The traditional production mode relies heavily on CAD engineers for manual nesting. Faced with hundreds of flange gaskets of different inner and outer diameters, it is necessary to import drawings, then manually drag, rotate, piece together, and arrange them on the computer, making constant manual adjustments, which is extremely time-consuming.
It seriously slows down the overall production rhythm, and no matter how experienced an engineer is, they cannot match the computing power of a computer. When encountering gaskets of multiple specifications and irregular shapes, it is almost impossible to optimize through manual work.
Material Waste Caused by Not Using Nesting Software
If only relying on basic control software or manual nesting without using nesting software, the holes between gaskets (such as the circular hole in the middle of a large flange) are usually directly discarded as waste. This results in a lot of leftover materials being thrown away, leading to severe material waste. Through our actual tests, if only manual nesting is used, the material utilization rate is usually only 65% – 75%, while it can reach 85% – 92% with intelligent nesting software.
Core Roles of Nesting Software in CNC Oscillating Knife Gasket Cutting Machines
The essence of nesting software is to replace the human brain with extremely complex mathematical algorithms, using powerful computing power to calculate the optimal nesting method in the shortest time, maximizing material utilization.
Automatic Nesting Improves Material Utilization Rate
Trustercnc’s nesting software adopts True Shape algorithm, which can accurately identify the irregular edges of each gasket and nest them tightly together, achieving minimal leftover materials and maximum utilization rate, thereby reducing material costs.
Reduce Labor Costs
The traditional method requires technical personnel to perform nesting, while nesting software can complete nesting automatically. There is no need to hire too many technical personnel, nesting personnel, or designers. Only one ordinary operator needs to click buttons on the control panel to complete the process, eliminating many tedious intermediate steps and greatly simplifying the operation process.
Optimize Cutting Path to Improve Efficiency
While optimizing nesting, nesting software also optimizes the cutting path, reducing the idle travel of the oscillating knife, repeated cutting, and optimizing the tool movement sequence, thereby significantly increasing cutting output per unit time. Studies have shown that optimizing the cutting path can improve production efficiency by 15%–25%.

Support Multi-Specification Order Production
Gasket production generally has the characteristics of complex orders, multiple specifications, and inconsistent quantities, but nesting software can achieve mixed nesting of different sizes. For example, when you receive different orders from five customers, you can automatically arrange parts of different sizes on the same plate, improving production flexibility.
Key Functions of Trustercnc’s Nesting Software
Trustercnc’s nesting software has an intuitive and easy-to-use interface, built-in 2D CAD functions and a library of variable-shape parts. It can automatically set entry curves and feed rates; the software supports fast manual nesting and intelligent automatic nesting, maximizing plate utilization. It also has functions such as ERP/MRP integration, plate inventory management, work order processing, cost accounting, and material utilization rate management reports.
You only need to enter cutting parameters, and the system will automatically match applications according to the specific material type, thickness, and part geometry, achieving smoother cutting edges, sharper corners, and better hole cutting quality; users can also track and count the cutting time, material consumption, and costs of each project through the built-in reporting tool.
Automatic Nesting Function
Trustercnc’s nesting software has an automatic nesting function, also known as “nesting small circles in large circles”. It is not just simple rectangular nesting; it can achieve advanced True Shape Nesting. The software can automatically and accurately “insert” small-sized O-rings or micro gaskets into the waste holes in the center of large flange gaskets (nesting in holes), achieving zero waste.
Intelligent Path Optimization
It has a Common-line Cutting function. That is, when cutting gaskets with straight edges, the software will allow adjacent parts to share one cutting line. The machine only needs to make one cut to produce two parts, saving both materials and cutting time.
Material Utilization Rate Calculation
Before cutting, the software interface will display the material utilization rate percentage of the current nesting in real time (such as 82%, 90%, 92.5%) and the number of plates required, allowing you to select the one with the highest utilization rate.
Built-in Deformable Part Library
Our nesting software has a built-in library of more than 150 gasket design parts, which can automatically achieve nesting according to customer needs without importing additional CAD design graphics, truly realizing design-free operation.
Automatic Import of CAD Files
It is compatible with mainstream design software such as AutoCAD and SolidWorks, supporting one-click batch import of formats such as DXF, DWG, and PLT, reducing conversion time. It can also automatically repair unclosed broken lines in drawings.
Batch Order Nesting
Built-in Work Order Management module. You can directly enter “for example, 500 gaskets of Model A, 200 of Model B”, and the software will automatically allocate the required number of materials and complete all nesting according to the required quantity and inventory plate size.
Real-Time Production Preview
You can observe the cutting path, nesting results, and material usage in real time on the software operation interface, and correct errors in a timely manner if found.

How Can Nesting Software Help Enterprises Save More Than 30% in Material Costs?
Nesting software can significantly improve material utilization rate, which is visible to the naked eye. Through our actual cutting tests and feedback from customers’ actual production, Trustercnc’s nesting software can help enterprises save at least 30% in material costs.
Automatic Nesting Reduces Leftover Waste
The software will automatically calculate to achieve minimal gaps. Trustercnc’s nesting software can even control the gap between parts within 1mm, making full use of the wide leftover materials that would otherwise be scrapped.
Improve Plate Utilization Rate
In the field of 2D irregular bin packing, advanced heuristic algorithms play a decisive role in improving material utilization rate. Studies have shown that adopting advanced automatic nesting algorithms (such as genetic algorithms or simulated annealing algorithms) can increase raw material utilization rate by an average of 15% to 25% and significantly reduce the loss of high-value materials.
For relevant research results, refer to Elsevier journal papers, such as “A heuristic algorithm for the two-dimensional irregular bin packing problem” and “Optimization of 2D irregular shape nesting for CNC cutting using genetic algorithms”. Source reference: ScienceDirect
Reduce Human Errors
Manual nesting is likely to cause significant errors, and the errors caused by nesting personnel with different experience will also vary. However, nesting software will not have any errors. Every step of its operation is precisely calculated, thus eliminating the waste or scrapping of expensive materials due to nesting mistakes.
Calculate How Much Trustercnc’s Nesting Software Can Save for Your Factory
Suppose your factory processes a large number of imported PTFE (polytetrafluoroethylene) plates with a thickness of 3mm, and the price of each standard plate (1500mm x 1500mm) is about 2,000 US dollars.
Traditional manual nesting: Calculated at a utilization rate of 75%, each plate wastes materials worth 500 US dollars.
Using Trustercnc’s nesting software: The utilization rate is increased to 93%, and each plate only wastes materials worth 140 US dollars.
Savings per plate: 360 US dollars.
If one machine in your factory cuts 20 such plates every day:
Daily savings in material costs: 360 US dollars × 20 plates = 7,200 US dollars.
Monthly savings (based on 25 days): 7,200 US dollars × 25 days = 180,000 US dollars.
From the above calculation, it can be seen that the saved material costs are enough to buy a brand-new high-configured CNC oscillating knife cutting machine.
Differences Between Trustercnc’s Nesting Software for CNC Oscillating Knife Gasket Cutting Machines and Ordinary CAD Nesting
Trustercnc’s nesting software for CNC oscillating knife gasket cutting machines is essentially different from ordinary CAD nesting in underlying algorithm logic. Trustercnc’s nesting software adopts True Shape intelligent optimization algorithm, while ordinary CAD nesting requires more manual participation.
Manual Nesting Mode
Ordinary CAD nesting requires manual copying, pasting, and rotating graphics in AutoCAD. This is an extremely tedious and inefficient manual task, and the tightness of the nesting depends entirely on the experience of the nesting personnel.
Automatic Nesting Mode
Trustercnc’s nesting software uses the multi-core computing power of the computer to perform tens of thousands of geometric collision tests in one minute, and finally selects the optimal solution. This is incomparable with ordinary CAD nesting software.
Comparison of Material Utilization Rate
Ordinary CAD manual nesting rarely breaks through the 80% utilization rate bottleneck; while Trustercnc’s industrial-grade nesting software can easily exceed 85%, and when processing flange gaskets including nesting of large and small sizes, the utilization rate often reaches 90%-95%.
Comparison of Production Efficiency
Nesting 100 gaskets of different specifications may take 2-3 hours with manual CAD; nesting software only takes one minute.
Comparison of Labor Costs
If using ordinary CAD, you need to hire a very experienced draftsman, and the labor cost will be a large expense. With nesting software, only one ordinary operator is needed — you just need to enter the required parameters in the software to complete nesting.
How to Choose Nesting Software When Purchasing a CNC Oscillating Knife Gasket Cutting Machine
There are many types of nesting software on the market. Some nesting software is very cumbersome to use and requires more operation steps to complete, which will be a tedious task for ordinary factory employees. We once had a customer from Canada who chose us among many suppliers because our nesting software does not require too many tedious steps — you only need to enter parameters to complete nesting. Therefore, an easy-to-operate and compatible nesting software is particularly important.
Compatibility with the Equipment System
High-end nesting software should have high compatibility, and the G-code generated by it can be imported into any brand of machine. The CNC code output by Trustercnc’s industrial-grade nesting software can match almost all brands of CNC oscillating knife cutting machines on the market, with excellent compatibility.
Support for Automatic Optimization
Avoid purchasing “semi-finished” nesting software that can only nest but not optimize. A good nesting software must be able to automatically post-process and optimize the cutting sequence and starting point position after nesting.
Ease of Operation
A good nesting software should not only be practical but also easy to operate. It is crucial to choose a system with an intuitive UI interface and guided operation. Trustercnc’s nesting software can complete nesting in a few seconds by simply entering the corresponding cutting parameters in the input box.
Support for Multiple Materials
The safety distance between gaskets is different when cutting soft silicone and hard non-asbestos boards. The software must allow you to customize part spacing and edge margins for different materials.
Provision of Technical Support
Software requires continuous updates and maintenance. Choose a supplier that provides lifelong technical guidance and remote assistance. Trustercnc regularly upgrades the software and provides free lifelong technical support.
Development Trends of Nesting Software for CNC Gasket Cutting Machines in 2026
With the rapid development of AI, we have made a bold guess about the future development trend of nesting software: in the future, nesting software may be connected to AI, making it more intelligent and achieving a high degree of automation and intelligence. Specifically, it may be reflected in the following five aspects:
AI Automatic Nesting
Relying on Machine Learning, the software can continuously evolve and learn according to your factory’s past nesting habits, and the nesting speed will be improved from the current “second-level” to “millisecond-level”.
Cloud Production Management
No longer limited to single-machine operation, managers can real-time view the machine’s nesting utilization rate, material consumption, and cutting progress through a mobile APP on the cloud.
Intelligent Material Analysis
The system can automatically analyze which specifications of raw materials are most likely to generate waste recently, thereby reversely guiding the procurement department to adjust the procurement size of plates.
Automatic Cost Calculation
Integrated with a Quoting Module. Sales personnel only need to import customer drawings, and the software can provide accurate material costs and processing time down to the cent in 1-3 seconds, greatly improving the efficiency and accuracy of external quotations.
Digital Factory Integration
Nesting software will provide open API interfaces, seamlessly connecting with the factory’s ERP/MES system, realizing the Industry 4.0 closed-loop management from order receiving, nesting, cutting to inventory deduction.
Which Enterprises Need Nesting Software for CNC Oscillating Knife Gasket Cutting Machines Most?
Sealing Gasket Manufacturers
Faced with extremely complex specifications and models and expensive materials, cost control is the fundamental for enterprises to survive.
Rubber Products Factories
For example, gasket production and processing factories mainly using Viton Rubber as raw material.
Industrial Material Processing Factories
Involving the processing of special non-metallic flexible materials such as PTFE, mica boards, and cork.
Mechanical Sealing Enterprises
The products have high added value, and the requirements for gasket cutting edge quality and dimensional tolerance are extremely strict.
Enterprises Producing Multi-Specification Orders
Receiving dozens or even hundreds of fragmented customized orders from different customers every day, and urgently needing flexible rapid response capabilities.
FAQs
Most of the workers in our workshop have no professional CAD drawing foundation—can they learn it?
Our nesting software does not require any CAD drawing skills at all. You can complete nesting in just three steps:
Step 1: Import the DXF drawings sent by the customer.
Step 2: Enter the quantity to be cut.
Step 3: Click “One-Click Automatic Nesting”.
Usually, only one ordinary operator can be fully qualified for independent work after 1-2 days of systematic training provided by us.
What is the charging model for this software? Is it a one-time purchase for life or an expensive annual subscription fee?
If you choose to purchase our machine, we will provide you with a gasket cutting solution and deliver the nesting software together with the machine. It is a one-time purchase for life—you don’t have to worry about paying an annual subscription fee after purchasing. Moreover, we also provide you with free technical training and free video tutorials.
Customers often send poorly quality CAD drawings (such as unclosed lines, overlapping lines)—can the software process them before nesting?
Absolutely.
If you directly nest drawings containing “overlapping lines”, the machine may cut twice in one place, resulting in gasket scrapping.
Trustercnc’s nesting software has a powerful Auto-healing function for drawings. When you import the customer’s poor-quality DXF drawings into the system, the software will automatically scan and “clean up” this garbage data in the background: it will automatically merge overlapping lines, close tiny break gaps, and smooth rough curves. This saves your factory’s engineers a lot of time in manually repairing drawings in AutoCAD.
Some of the rubberized fabric gaskets we process have fiber textures, requiring the force direction of the cut gaskets to be consistent — will the nesting software rotate them randomly?
Please rest assured, absolutely not.
Trustercnc’s industrial-grade nesting software fully considers the physical characteristics of special materials and has a “Grain Constraint” function.
Before nesting, you can set rotation restriction conditions for specific gasket graphics. For example, you can lock the graphic to “absolutely prohibit rotation” or “only flip 180 degrees”. In this way, during automatic nesting, no matter how dense the algorithm is, it will strictly ensure that the internal fiber direction of all cut gaskets is completely consistent, perfectly meeting the force standards for heavy-duty flange sealing.
Our factory already has an old oscillating knife equipment of another brand—can we directly purchase Trustercnc’s nesting software separately to upgrade the utilization rate?
Although our nesting software is highly compatible and can output universal G-code to almost any brand or model of CNC machine tool on the market, we do not recommend you to directly purchase our nesting software to upgrade your machine.
Because nesting that can achieve an extreme material utilization rate of more than 90% must rely on the deep coupling between the software algorithm and the machine’s underlying control system (especially motor motion interpolation and tool lifting height control). Older equipment of other brands may not be able to execute the complex “common-line cutting” or “micro-distance interspersing” paths planned by advanced nesting software in terms of mechanical rigidity and system response speed.
To achieve the best material saving and efficiency improvement effects, purchasing a complete set of Trustercnc cutting system with seamless hardware and software compatibility is the most cost-effective and lowest-risk upgrade solution.
Must a CNC oscillating knife gasket cutting machine be equipped with nesting software?
If your factory mainly cuts expensive high-value materials, it is recommended that you equip it with nesting software.
The main reasons are:
- Material costs account for 60%–80% of production costs.
- Manual nesting is inefficient.
- Severe material waste without using nesting software.
In actual production, the material utilization rate without using nesting software is usually only 65%–75%, while it can reach 85%–92% with nesting software. For expensive materials such as PTFE, Viton, and non-asbestos boards, a lot of costs can be saved in the long run.
