In machining and manufacturing, how to correctly select measuring tools?

In Machining and manufacturing, like other functions, measurement is also an important topic of management efficiency, cost control or cost containment. So how to choose suitable measuring instruments in machining and manufacturing?

In fact, we need to choose the quantity instrument suitable for your needs. First, we need to determine the functional requirements of the measurement task, and then choose the quantity meter that can meet these hard requirements.

There are many factors to be taken into consideration in determining the functional requirements, it can be referred to as follows:

1. the character and type of the workpiece being measured: is it flat, round or other? Is it the inner diameter or the outer diameter? Is the position easy to contact? Is the boss near him, or is it a hole or a narrow slot?

2. Accuracy:Is the accuracy of the instrument suitable for the tolerances of the workpiece to be measured?

3. Test cost: as the accuracy of the meter increases, the cost will increase dramatically. To get close to tolerances, before setting up a measurement operation, you need to verify whether you need to choose a very expensive instrument.

4. time and capacity: fixed or dedicated meters are more economical than flexible and versatile ones. It depends on whether your capacity is batch or multiple parts. You also need to consider which instrument can really save your surveyor's time in the production cycle.

5. easy to use: especially the meter factory, you should be to reduce the skill requirements of inspection personnel and inspectors may.

6. Maintenance cost: meter maintenance or throw away, how long should it be maintained once? Who is to maintain? After a long period of operation, the accuracy will be lost. You need to take some measures to ensure accuracy.

7. Parts cleaning: are parts dirty or clean during the measurement? This may affect the experimental conditions, maintenance accuracy and level. Can the selected instrument be used normally in your measuring environment? Or do you use an air momentum meter? It has a self cleaning function.

8. Measurement environment: the instrument is easily affected by dust, vibration and temperature changes. Will the instrument you choose be affected by these effects?

9. Maneuverability: do you measure moving parts or mobile measuring tools? So which measure is suitable for?

10. Workpiece processing: what do you do after part testing? Are unqualified parts scrapped or re-do? Is there a series of necessary conditions?

11. Tool materials and finishing Quality: can parts be compressed? Is it easy to scratch? Many standard gauges can be modified to avoid these effects. Do you have a note on this point of attention?

12. Money: what's the price of your choice? What's your budget?

When you start a test task, you need to confirm what type of measure you choose, and all of these factors are important. They can help you define as much as possible, narrowing the scope of your choice to facilitate the final choice.
