How to measure workpieces in CNC machining? Measurement methods and their applications
Precise measurements play a key role in CNC machining processes such as milling, turning and drilling. The main goal is to ensure that the dimensions of the workpieces conform to technical requirements and maintain high production quality. Dimensional accuracy directly affects the functionality and durability of final products, so it is essential to constantly control machining parameters, especially in serial production, where repeatability is a priority. Measurements also make it possible to quickly detect and correct deviations, which minimizes material losses. In advanced manufacturing processes such as those used at SIM Gdynia, measurements are an integral part of quality assurance. Traditional measurement methods Traditional measuring tools, such as calipers and micrometers, have been the cornerstone of dimensional control in CNC machining for decades. Calipers can measure lengths, diameters and depths to an accuracy of about 0.02 mm, making them versatile tools. Micrometers, on the other hand, offer an accuracy of up to 0.001 mm, making them suitable for measuring workpieces that require greater precision, such as shafts and bushings. Despite their versatility, traditional tools have limitations. Measuring complex shapes or workpieces with complex geometries can be time-consuming and subject to greater risk of error. In such cases, it becomes necessary to use more advanced technologies that automate the measurement process and achieve greater accuracy. Modern solutions – coordinate measuring machines Coordinate measuring machines (CMMs) represent a state-of-the-art approach to dimensional control in CNC machining. They enable precise measurement of workpieces in three axes (X, Y, Z) using contact or non-contact probes. Measuring machines such as Mitutoyo’s offer the ability to measure complex geometries with accuracy down to microns. The machine works on the principle of collecting points from the surface of the workpiece, moving along pre-programmed trajectories. The measurement program for each workpiece is created once, which guarantees repeatability and standardization of the process for subsequent measurements. At SIM Gdynia, we use such solutions to obtain detailed dimensional analysis of parts with complex shapes, which allows us to maintain high quality standards. The design of the measuring machine makes it possible to measure parts with large dimensions, such as machine parts or components used in aviation. By automating the measurement process, the impact of human error can be minimized and the speed of dimensional analysis can be increased. 3D scanners and laser sensors in CNC measurement Today, industry is increasingly using non-contact technologies such as 3D scanners and laser sensors. Scanners allow comprehensive mapping of the geometry of a workpiece, which is particularly useful for parts with irregular shapes. The technology enables the creation of 3D models that can be used for comparison with CAD data and for further analysis. Optical and laser sensors offer precision and speed, making them ideal for real-time measurements, especially in mass production. Their use minimizes the risk of damage to the workpiece, which is important for delicate or deformation-prone materials. How to choose the right measuring methods? Choosing the right measuring tool depends on several factors, such as dimensional tolerances, workpiece geometry and surface quality requirements. For simple workpieces with less stringent tolerances, traditional tools such as calipers or micrometers may be sufficient. However, for more complex workpieces that require analysis in multiple planes, coordinate measuring machines or 3D scanners are the best solution. At SIM Gdynia, we take a diverse approach to measurement, adapting methods to the specifics of the project. As a result, we are able to ensure precision in both unit and batch production. Summary Measurement in CNC machining is the foundation of precise and efficient production. From traditional tools such as calipers and micrometers to advanced CMMs and 3D scanners, each technology has its place depending on the specifics of the project. At SIM Gdynia, we are constantly developing our measurement capabilities, using the latest technologies to deliver products that meet the most stringent technical standards. This allows us to offer our customers reliability, repeatability and the highest quality at every stage of order fulfillment.
Centerless grinders – the key to precision grinding in modern industry
What are centerless grinders and why are they important? Centerless grinders are specialized machines designed for precision grinding of straight-shaped workpieces, such as shafts or bushings. A unique feature of these machines is the lack of classic workpiece support, which means that the material is not fixed at a single point, as is the case with traditional grinders. The workpiece moves freely along the abrasive disc, which simultaneously rotates in the opposite direction. This solution eliminates so-called “fangs” – surface irregularities that are a common problem in traditional grinding processes. Thanks to this technology, it is possible to achieve high surface quality, which is crucial for workpieces requiring exceptional dimensional accuracy and appropriate finishing parameters. Principle of operation of centerless grinders In the process of centerless grinding, the control of parameters such as rotational speed, contact force and workpiece travel speed plays a key role. The workpiece is freely supported between two discs: one rotating at high speed and the other responsible for stable sliding. This arrangement eliminates the need for support points, which reduces the risk of surface damage. To maintain the quality of the process, cooling systems are also used to reduce friction and minimize the risk of material overheating. As a result, workpieces maintain dimensional stability and proper technical parameters, even when machining parts that require tight tolerances. Types of centerless grinders and their applications Centerless grinders can be divided into several types depending on their application and design: How do centerless grinders support production at SIM Gdynia? At SIM Gdynia, we have implemented centerless grinding technology to meet the demands of manufacturing high-precision parts. Thanks to the use of these machines, we have significantly improved the efficiency of our machining processes, which allows us to complete orders in less time while maintaining the highest quality. One of the main effects is the achievement of surface smoothness, which is crucial for parts used in dynamic systems, such as sealing rings and machine components. In addition, shortened machining cycles and reduced material losses translate into optimized production costs. With centerless grinders, we are able to offer our customers products that meet the most stringent technical standards. Summary Centerless grinders are an essential part of modern machining, enabling precise and efficient production of cylindrical parts and parts with irregular shapes. Their use makes it possible to achieve a high quality surface finish, eliminating the problems associated with traditional grinding methods. At SIM Gdynia, we use this technology to realize orders at the highest technical level, while optimizing production time and costs. This allows us to effectively support our customers in achieving their industrial goals.

What are CNC gear milling machines? CNC orbital milling machines are specialized machines used in machining, designed for the production of gears with an orbital tooth profile. Thanks to the use of numerical control technology, they make it possible to precisely reproduce the shape of the teeth in accordance with strict dimensional standards. These devices are used in the production of components requiring high accuracy, such as drivetrain components used in the automotive, aerospace and engineering industries. How do CNC envelope milling machines work? A CNC orbital milling machine enables gears to be machined by precisely controlling the trajectory of the cutting tool, which allows the teeth shape to be accurately reproduced. The process is carried out on several working axes that operate simultaneously, allowing multidirectional movements of the tool. Thanks to CNC programming, it is possible to plan each machining step with high accuracy. This organization of work minimizes the risk of errors and ensures repeatable production. As a result, gears that meet quality standards can be obtained. Challenges in the gear cutting process The gear cutting process involves the need to maintain very tight dimensional tolerances. Even small deviations in the shape or dimensions of the teeth can affect the functioning of the mechanism in which they are used. An important part of the process is the geometry of the cutting tool – the peripheral cutter – and its proper alignment. Precise adjustment of parameters such as rotational speed, feed rate and tool angle is key to achieving a high-quality product.
