    Smart Manufacturing in the automotive industry

    In the dynamic realm of automotive manufacturing, innovation is non-
    negotiable. As manufacturers move toward smarter factories, virtual Computer Numerical Control (CNC) software has become a key enabler of smart manufacturing, revolutionizing traditional machining workflows into connected, data-driven processes.
    This white paper explores how virtual CNC software supports smart machining in automotive manufacturing by improving efficiency, precision, and agility.

    Virtual CNC software enables automotive manufacturers to simulate and optimize machining processes before physical production commences. By digitally modeling components and machining behavior, potential errors are identified early, lead times are shortened, and resource utilisation is improved. These capabilities directly support smart factory initiatives, driving higher productivity and cost-efficiency across machining operations.

    Additionally, through realistic simulations of machining operations, operators and engineers can enhance their skills in a safe, controlled environment, eliminating the need for costly physical prototypes or machine time.

    As the automotive industry evolves, integrating virtual CNC software becomes a strategic imperative for manufacturers. By embracing this technology, companies can unlock new avenues for growth, efficiency, and innovation.

    Vericut’s commitment

    The automotive industry has been through major changes and those that have survived have been prepared and adaptable. The more recent shift towards electric vehicles, plus the future outlook on more autonomous vehicles, come with great challenges for the industry.

    Alongside other priorities, the goal of energy-efficient manufacturing – reducing energy consumption and increasing sustainability – is at the top priority for all manufacturing businesses. To meet these challenges, automotive manufacturers must reallocate budgets decisively toward smart manufacturing solutions that enhance production performance while controlling costs. Investment in software and manufacturing feasibility is critical to improving product quality and ensuring long-term competitiveness.

    Focusing primarily on processes, rather than on individual machines, systems, or functions. Even in a downturn scenario, fast, decisive action on investments in the next technological generation for better workflows must not be taken for granted.

    Of course, the possibilities of smart alternatives in automotive manufacturing are based primarily on stringent digitization. It is not for nothing that NC simulation is considered a lighthouse project and early mover among the digital game changers as the interface between CAM programming, work preparation, and the shopfloor.

    Manufacturing simulation of the NC data, i.e., the machine code, addresses the really important fields of action in metal-cutting manufacturing: safe, prove-outs of complex clamping situations, manufacturing without scrap, machining without machine collisions, increasing tool life, faster NC programs with reduced machining times and improved part quality.

    5 Grand challenges in the automotive industry

    1. Supply Chain Disruptions: 

    Potential disruptions in the supply chain, such as those caused by geopolitical tensions or natural disasters, can lead to price fluctuation and shortages. Anticipating these disruptions can mean successfully mitigating potentially fragile manufacturing situations and maintaining stable operations.


    Tip: Beyond the typical corporate activities to counter impending supply problems, companies must achieve new levels of internal efficiency to address the need for materials and energy. Focus is on planning production efficiently from the start, and digital solutions that combine both quality assurance with autonomous production control will increase the resource efficiency of manufacturing processes. 

    2. Technological Advancement

    With the rapid advancement in technologies like electric vehicles and autonomous driving systems, manufacturing processes must remain adaptable and flexible to incorporate these changes quickly and efficiently. Investments in new initiatives and technology adoption within manufacturing facilities.


    Tip: Changes in the automotive industry will require new types of components, tooling and processes. High volume will remain key to the industry, and any mistakes can be costly. Consider the production environment – the machines, their automation, the required floor space, raw materials and invested capital – and the initial information required for accurate process planning – machining operations, required tools, the cycle time, production rate and requirements.  

    3. Sustainability & Environmental Regulations:

    Politically intended and socially approved, sustainability is an obvious and logical goal. Companies often see it as their duty to implement the principle and practice of sustainability. If done correctly, specific measures can be positioned within manufacturing processes and product design to reduce environmental impact and to comply with regulatory standards.

    Tip: To minimize the CO2 footprint, for example, companies will want to use raw materials and energy efficiently. Quickly digitizing defined manufacturing segments is a good example, reducing the material used, energy spent, and time wasted on manual prove-outs.  

    Safely testing and producing any parts in a virtual environment often negates the need to physically test run, or prove-out, a part prior to production, which removes the chances of scrapping (wasting) raw material to generate an erroneous part, along with chance that the NC program might contain errors that could cause the machine tool to crash and become damaged.

    Optimizing the NC code to produce a more efficient program results in manufacturing cycle time savings of between 10% and 40%, depending upon the raw material and complexity of the parts. The savings from wasted time and power consumed are significant.

    4. Quality control & Product Safety:

    Maintaining product quality and safety is crucial in the automotive industry. Having quality control measures and protocols in place throughout the manufacturing process to identify defects or issues early on is essential to production schedules, cost control and customer satisfaction.


    Tip: Every step in the process – engineering, design, CAM programming and machining – should be inspected, verified and optimized. Simulation and verification technology ensures programs are error free and all operations work together as intended. Optimization ensures the whole process is operating as efficiently as possible to save time and money. 

    5. Workforce Skills & Training:

    Continuous development of the workforce and improving their skills will increase productivity, improve the quality of work, and reduce faults, waste or customer complaints. As industry and manufacturing technologies evolve, this also applies to the workforce.

    Tip: There is no denying that skilled machinists are hard to come by. With a large percentage of the current workforce of NC programmers and machinists getting ready to retire and a shortage of newly qualified engineering talent, finding people to work in this industry and fill the void is becoming increasingly more difficult.

    Software can provide a large amount of data and information that can be used to improve the manufacturing workflow and free up a skilled machinist’s time.

    Engineering companies are now facing the challenge of meeting increased demands and staying competitive with fewer programmers and machinists. Working smarter with software reduces the need to fill all those voids.

    CNC simulation software can verify a part, simulate the machining and optimize the NC programs before any real machining has started. Therefore, making unattended or lights out machining, and the ability to operate with less machinists, a reality.

    3 Facts about NC simulation

    1. Procedures in Profile

    Wherever milling, drilling or turning is done based on NC programs, NC simulation software simulates the original NC code after the post-processing. Checking and optimizing toolpaths are among the best practices for manufacturing optimization.

    For users, the most reliable approach is to simulate an actual machining situation with a “virtual machine tool on the desk”. Ideally, NC simulation should operate independently of the CAM programming system, CNC machine, and controls.

    Special benefits for automotive

    Independence promotes connectivity. This is particularly advantageous in manufacturing environments with a wide range of machines, systems and software.

     

    2. Present & Future

    The simulation, verification, and optimization of CNC machines allows for reliable planning by virtually mapping future processes in the present and eliminating potential errors in the NC program before physically machining a workpiece.

    Special benefits for automotive

    Shorter cycle times and safe test cuts are critically important. Increased tool life, reduced tool breakage, no damaged fixtures, and no machine collisions are practical investments.

    3. Resource Management

    NC simulation creates a sense of certainty for production planning through the precise determination of manufacturing times. This makes it easier to optimize traditionally sequential workflows in metal-cutting production and opens up the ability to run parallel projects. NC machining simulation enables better machine utilization, employee relief from routine tasks and program rework, and fewer delays or rescheduling of production plans.

    Special benefits for automotive

    The current shortage of skilled workers and higher sickness rates are critical in an already tense market environment. In the face of shifting market trends, changes to customer demands, unprecedented stringent quality requirements, and the growing use of new technology, adequate employee motivation and resource management are of utmost importance in industries where producing high quality machined parts, in the least amount of time, and at the lowest possible cost is the primary goal.

    Capital expenditures & Depreciation NC simulation

    The industry is under enormous pressure to innovate, but this requires a balanced approach in financial and operational strategies. Implementing and utilizing new technologies, new materials, and new manufacturing processes can pose large challenges for companies, especially mid-sized suppliers. Companies that also operate outside the automotive industry often have to carefully weigh whether the quantities they produce within the industry justify the high costs associated with these new investments.

    Nearly every budget set aside for innovation is the subject of intense discussion. An investment in NC simulation, however, is typically out of the question. A rough calculation of the return on investment with NC simulation is extraordinary and can be paid back in as short a time as machining a single workpiece. NC simulation has been used since the 1980s, utilizing digital twins of the CNC machine, workpiece, and the NC program, making it one of the main players and a key investment in today’s Industry 4.0 initiatives.
