Product introduce:
In the machining process, the common methods of sheet cutting are manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but the quality of manual cutting is poor, the size error is large, the material waste is large, the subsequent processing workload is large, and the labor conditions are harsh and the production efficiency is low. Among the semi-automatic cutting machines, the profiling cutting machine has better quality of cutting workpieces. Because it uses a cutting die, it is not suitable for single piece, small batch and large workpiece cutting. Although other types of semi-automatic cutting machines reduce the labor intensity of workers, they have simple functions and are only suitable for cutting parts with relatively regular shapes. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the efficiency and quality of plate cutting, and reduce the labor intensity of operators. With the development of the modern machinery industry, the requirements for the work efficiency and product quality of plate cutting processing have also increased at the same time, so the market potential of CNC cutting machines is still very large, and the market prospects are relatively optimistic.

Usually, the CNC cutting system automatically processes the processed parts according to the pre-programmed processing program (the commonly used drawing software AUTOCAD). We put the machining process route of the part, process parameters, tool motion trajectory, displacement, cutting parameters (spindle revolutions, feed, back-feeding amount, etc.) and auxiliary functions (tool change, spindle forward rotation, reverse rotation, The cutting fluid is turned on and off, etc.), according to the instruction code and program format specified by the CNC cutting system, write a processing program list, and then record the content of the program list on the control medium (such as perforated paper tape, magnetic tape, disk, magnetic bubble, etc.). memory), and then input into the numerical control device of the numerical control machine tool, thereby directing the machine tool to process the parts.
This whole process from the analysis of the part drawing to the production of the control medium is called the compilation of the numerical control program. The difference between CNC cutting equipment and ordinary manual and semi-automatic cutting equipment in processing parts is that CNC cutting equipment automatically processes parts according to the program, while ordinary manual and semi-automatic cutting equipment needs to be operated by humans, we only need to change the control machine action. The program can achieve the purpose of machining different parts. Therefore, CNC cutting equipment is especially suitable for processing parts with small batches and complex shapes that require high precision!
Since the CNC cutting equipment needs to process parts according to the program, after the programmer has compiled the program, it is input into the CNC system to direct the machine tool work. Program input comes through the control medium. In this way, the CNC system is used to control the finished processing parts, and the graphics can be modified in time by the drawing staff, which can be used more freely, and the accuracy of the workpiece parts is also greatly improved compared with that of semi-automatic cutting equipment!

As someone who previously oversaw a statewide rollout of engineering software during my time at the Wisconsin Department of Transportation, I can fully appreciate the monumental effort it takes to reach milestones like those achieved by California’s Department of Transportation (Caltrans). Managing over 50,000 miles of highways and freeways, along with numerous other critical transportation assets such as intercity rail services and public-use airports, Caltrans plays an indispensable role in maintaining California's infrastructure.
Back in June 2011, Caltrans took a bold step forward by replacing its aging Autodesk CAiCE software with AutoCAD Civil 3D for statewide road and highway design projects. This shift aligns with a broader global trend toward adopting Building Information Modeling (BIM) practices and tools to enhance efficiency and collaboration in infrastructure development.
Now, in their second year of implementing AutoCAD Civil 3D, Caltrans has trained almost 2,000 engineers and surveyors on the new system. Their progress has been recognized internally through a recent directive from the Chief of the Division of Design, which mandates that all new projects initiated after July 1, 2014, must utilize Civil 3D. This marks the official phasing out of CAiCE within Caltrans operations.
The transition isn't without challenges, but the benefits are evident. For instance, Caltrans has developed custom software standards and workflows tailored to their specific needs, ensuring compliance with unique state regulations while streamlining workflows for both internal staff and external partners.
One compelling example of how these advancements are paying off is the 3D visualization created for the Presidio Parkway project in San Francisco by Parsons Brinckerhoff. Such visualizations not only aid in planning but also facilitate better communication among stakeholders.
Similarly, the El Dorado County Department of Transportation leveraged AutoCAD Civil 3D to deliver a sophisticated design solution for one of their roadway projects, showcasing the versatility and power of modern CAD tools in addressing complex real-world scenarios.
If you're interested in learning more about Caltrans' journey or exploring similar solutions offered by Autodesk for road and highway management, there are plenty of resources available online. This story originally appeared on Autodesk's BIM on the Rocks blog, where industry professionals often share insights into cutting-edge technologies reshaping our world.
