Equator's innovation and high repeatability measurement technology are based on the traditional comparison method between production parts and standard parts. Re checking is as fast as measuring production parts and can immediately compensate for any thermal effects. Equator can be used in factories with large temperature changes. Simply recalibrate and reset the system to zero, and it will be ready for repeatable comparison with standard parts.

Traceable to calibrated coordinate measuring machines

Standard parts are not necessarily customized components that are as expensive as traditional measuring blocks; By taking a production part and measuring it on a coordinate measuring machine (CMM), feature changes can be established from CAD or drawing standards. The results obtained from any coordinate machine that executes any coordinate measuring machine programming software can be configured for direct use in Equator software.
In fact, the calibrated absolute accuracy of coordinate measuring machines (usually located in remote temperature control rooms to ensure accuracy) can be "extended" to factories, providing calibration traceability for Equator measurements. Due to the calibration file being loaded into the Equator software, measurements taken in the Equator system can be returned to CAD or drawing standards. This can achieve true process control through SPC components.

Comparison of 'standard' components

Scan known qualified workpieces or "standard" parts to generate a standard dataset. The same scanning program applies to each of your production items. Compare each production dataset with the standard dataset to determine if the relevant workpiece is within the user-defined tolerance range.

Comparison of "workpiece nominal"

It can also be used to determine the normal size of the production workpiece. Simply measure the standard components on the coordinate machine, establish a calibration dataset, and normalize the subsequent comparisons. Then, the true deviation values of each workpiece's nominal values can be displayed.

Using a sturdy and reliable comparator makes process monitoring easier in the workshop environment. Due to its small size and easy installation, Equator can be effortlessly integrated into automated production lines and units. Equator is suitable for integrating process feedback and control into flexible production lines or machining units such as turning centers, machining centers, grinders, and other machine tools, and measuring workpieces on multiple machines. Equator can be installed by the operator and can start measuring within seconds, with strong flexibility and reliable measurement repeatability. It can be connected to the robot using optional input/output interfaces, or integrated into the automation unit by outputting measurement results to SPC components. Some SPC components also provide the ability to connect to specific modern machine tool controllers, which can update bias values and achieve true automated process control. The data from Equator can be used to repeatedly and reliably update biases, compensating for the effects of tool wear and thermal changes. Combined with robot workpiece handling, the comparator can support fully automatic online process control.

Browse the weight of measuring toolsRepetitionAnd reproducibility

The purpose of studying the repeatability and reproducibility of measuring tools is to demonstrate the ability of measuring equipment to measure specific parts.

Type 1- Simple repeatability testing, requiring one operator, one part, and multiple repeated measurements. The following indicators are used to indicate whether a measurement system produces consistent and accurate results when measuring a certain feature:
Cg: Compare tolerances with measured variables.
Cgk: Compare tolerances with measured variables and deviations.

Both values must be greater than 1.33 to indicate that the measurement system has this capability, and in some cases, values greater than 1 are also acceptable. Cg indicates the range of measured values, and Cgk also includes the deviation between the measured group value and the nominal value.

Type 2- Prove that the Equator comparator has repeatability and reproducibility in measuring specific features, independent of the operator. Testing requires multiple operators, multiple parts, and multiple repeated measurements. The uncertainty of Equator in measuring specific features is expressed as a percentage of tolerance, which is generally less than 10%, but can also reach up to 20%.
