    Complete NC programs – all aspects automatically covered

    Experienced employees know the importance of blanks being correctly set up and dimensioned. Modern CAD/CAM modules also focus on these aspects and enable 24/7 unattended manufacturing. The entire process is optimized by complete numerical control programs with collision-checked measuring paths and integral measuring cycles.

    Manufacturing in production machining has been under heavy pressure for some time. A critical parameter in this is the need of companies to utilize their highly automated machine centers as best as possible. Users who continuously and simultaneously manufacture different parts based on a pallet changer benefit from every improvement in automation. If they use an automated measurement solution, they can also manufacture during unattended late and night shifts without concerns and, as a result, can maximize utilization of their machines.

    Automated manufacturing cells increase productivity.

    Measuring probes automatically correct the reference point

    In an automated measurement solution, the software performs test functions that were previously done by the machine operator. The NC program starts automatically, but the system checks the part orientation and the blank dimensions before the manufacturing process begins. The measuring probe checks the size of the blanks and immediately corrects the reference points in the event of any deviations within the blank tolerance. Larger deviations that are above or below a specific preset tolerance prevent the manufacturing process from starting on the affected pallet (and only on the affected pallet). Any additional setup errors such as an incorrect blank position are also immediately detected before the start of manufacturing, ensuring manufacturing only starts for blanks that are correctly set up. This prevents the production of scrap or machine damage right from the start. This is an important function, as surveys show that errors of this type regularly occur.

    The measurement system checks part orientation and blank dimensions and corrects the reference point in the event of deviations within the specified tolerances.

    Integral quality checks ensure safety

    A goal in the manufacturing process is to have the machines or machine centers run unattended for as long as possible, and prevent reworking. The latter takes time, increases wear on the machine and increases material costs. The goal is to achieve high quality with the fewest possible correction iterations.
    Automated measurement systems offer significant added value in this context. These solutions also provide integral quality checking in the ongoing machining process – independently from measuring cycles in the control. This yields complete NC programs with toolpaths for turning, milling and drilling, including measuring cycles, with which machining centers can run unattended. All movements of the measuring probes, tools and machines are realistically simulated and checked for collisions. The measurement solution also checks the intermediate manufacturing stages for the actual machining. If an error or a problem occurs, manufacturing on the affected pallet is stopped, while the remaining applications continue undisturbed.
    For example, ruled geometries can be measured, checked and corrected in the manufacturing process, and electrodes can also be automatically checked. In both cases, integral quality checking increases the degree of automation, reducing quality iterations and overall machining time.

    In an automated measurement solution, the software performs the checking functions that were previously performed by employees.

    Finding the right solution

    Most leading CAD/CAM providers now offer automated measurement solutions. Users should select an uncomplicated tool that is capable of being used without significant implementation and training expenditures. It should be compatible with as many controls and machines as possible and should be consistently updated.
    Automated measurement solutions throughout the entire manufacturing process provide many advantages. However, under no circumstances are they a substitute for the competence of a machine operator. Instead, the measurement solution supplements and improves human expertise while ensuring an additional level of safety, not only for preventing the extreme scenario of a collision, but also for detecting alignment errors at the start or during the manufacturing process. The tool supports users in the careful use of their machines, helps prevent wear and optimizes material utilization.

    Automated manufacturing relies on digital twins for safety and maximum precision.

    Flexible team deployment

    Most manufacturing companies are now confronted by significant personnel bottlenecks. The software reduces the burden on the team and provides additional added value. The use of automated modules such as a measurement solution can also enable more flexible team placement in the manufacturing process. For example, it helps to significantly reduce the number of employees necessary in evenings and on weekends. In turn, the customer sees that using a measurement solution results in a consistently high level of safety and quality in the manufacturing process. It ensures that deadlines are met and is an especially appropriate tool for contract manufacturers.
