CMM Inspection

Manufacturers and testing services use coordinate measuring machines, or CMMs, to inspect the dimensional quality and characteristics of manufactured goods to ensure they meet design requirements. CMM inspections, offered by Coweta Tech Precision, use these machines to measure parts or the entirety of a three-dimensional object and compare those measurements against the design file's specifications. They measure objects along the X, Y, and Z axes to provide a three-dimensional assessment of the product.

CMMs work by having a probe that moves along the surface of a product or uses sensors to indirectly measure surface qualities. Along with its probe, each machine has a base or bed that holds the product and a computer that both directs the probe and gathers the resulting measurement data.

Because CMMs can measure components along all three axes, the machines can collect a lot of in-depth data about the item. The probe offers very sensitive readings because the CMM's attached computer notes the exact position of the probe against a product's surface, allowing it to map the measured object's orientation, size, features, and position. Some of the different types of measurements it can take include the following:

• Dimensional: CMMs can assess the entire dimension of a product by collecting measurements across all three axes.
  
  
• Profile: It can create in-depth profile readings of 3D and 2D parts.
  
  
• Angle: It can pinpoint and measure the angle or orientation of two points in relation to each other.
  
  
• Depth: Using a pair of stereo images, it can combine data from multiple points to measure the relative depths of holes or different levels of the product.

Capability Maturity Models (CMMs) are another process that prioritizes standardization and in-depth quality control. These models establish five levels of capability against which different individuals, teams, or work processes can be assessed. It operates as an indirect or comparative analysis tool for marketing strengths and room for improvement. The five levels of capability maturity models are:

• Level 1—Initial: Processes are inconsistent and arbitrary, placing the odds of success squarely on an individual. Processes are undocumented, unstandardized, and subject to relatively random success rates.
• Level 2—Managed: This level is more standardized than the first level. There has been a basic degree of process documentation and standardization. Processes have become repeatable, and tasks are generally successful if all the steps are followed appropriately.
  
  
• Level 3—Defined: Everyone involved in the process has a clear understanding of their role and what actions to take. Processes are well-documented and standardized, and there is a commitment to continuously improving the processes.
  
  
• Level 4—Quantitatively Managed: Now, the success of the processes themselves is measured. Managers can collect metrics about the processes and outcomes, analyze those results to make conclusions about the effectiveness of the processes, and make more effective changes.
  
  
• Level 5—Optimizing: Stakeholders make continuous, data-backed improvements to continuously improve work processes that drive increasingly good results.

CMM inspections are valuable throughout the manufacturing sector. As parts and assemblies become more complex, more specialized, and more efficient, manufacturers need tight quality control processes to ensure that parts fit the parameters of the original design project. So CMMs are used to inspect geometrically complex goods, molded or machined parts, electronic assemblies, and more. With advanced CMMs, manufacturers can measure everything from the dimensions to the smoothness of the surface finish to ensure quality compliance.
