Basic knowledge of measurement — how to choose measuring tools correctly?

In modern manufacturing, like other functions, measurement is also an important topic of management efficiency, cost control, or cost containment! (EN10204-3.1 、DIN ASTM GOST GB JIS ANSI BS)Approved metal companies near me Manufacturer

For example, a nonconforming part of OEM customers, may be just a small problem; as for the rapid assembly, this part choose a throw away, maybe just take him one or two seconds. But it may also lead to equipment failure of a potential, huge threat, may even lead to fatal the consequences.

In order to avoid the production of substandard products, avoid taking expensive litigation costs, even if the two pa rt size tolerance specifications are the same, managers will pay more attention to the inspection of the second parts to reach a higher level, and strive to 100%. this caused the expensive cost of quality management!

Many companies have the ability to test the economy from the lab to the company building or workshop site, therefore, machinists and engineers more responsible for quality problems. So how to choose suitable measuring instruments own? Measure the same size in a variety of ways, you can use a variety of measuring instruments. How do you choose?

For example, for a small part to measure its simple outer diameter, there are 7 different gauges to choose from: (EN10204-3.1 、DIN ASTM GOST GB JIS ANSI BS)Approved metal companies near me Manufacturer

1, panel method, using “V” shape block and lever table;

2, microscope;

3, dedicated meter;

4 gauge;

  1. Long strip inner diameter / outer diameter gauge of adjustable device;

6, hand ring gasket or pneumatic momentum instrument;

7, automatic parts processing system

Specifically, there are more available measurement methods… Many of these kinds of instrument, the price from high to low gap is big. In addition, in the precision, testing personnel’s measurement capability, the data output is different, so we confused. How to choose? How do you choose?

In fact, to select the instrument suitable for their own needs, first of all need to determine the functional requirements of their own measurement tasks, and then choose to meet these rigid requirements of the meter

A variety of factors should be taken into account in determining the functional requirements:

The characteristics of the workpiece to be measured, the type: is it flat, round, or other type? Is it an inner diameter or an outer diameter? Is it easy to contact? Is it convex, or is it a hole, or is it a narrow slot?

Accuracy: the accuracy of the workpiece tolerances and instrument resolution and repeatability should be a reasonable relationship between (usually 10:1), statistical test GR & R needs 20:1, the precision of instrument, workpiece you measured is appropriate? (EN10204-3.1 、DIN ASTM GOST GB JIS ANSI BS)Approved metal companies near me Manufacturer

Test cost: as the accuracy of the meter increases, the cost will increase dramatically. In order to approach tolerances, you need to verify whether you need to choose expensive instruments before you establish the measurement operation

Time and capacity: are fixed, dedicated gauges more flexible, versatile, and more economical? Depending on whether your capacity is in batches or multiple units. You also need to consider which meter in the production cycle can actually save you the time of the surveyor

It’s easy to use and easy to use: especially in factories, you should reduce the skill requirements of inspectors and the possible impact of inspectors

Maintenance costs: instrument maintenance or throw away, how long maintenance time? Who maintenance? After a long period of operation, will lose precision, you need to take some measures to ensure accuracy. (EN10204-3.1 、DIN ASTM GOST GB JIS ANSI BS)Approved metal companies near me Manufacturer

Cleaning of parts: are you dirty or clean during the measurement? This may affect the experimental conditions, maintenance accuracy and level. Whether the measuring instrument can be used normally in your measurement environment or whether you use the air momentum meter, it has the function of self cleaning

Measuring environment: the meter is susceptible to dust, vibration, temperature changes, you choose the instrument will be affected by these?

Mobility: do you measure moving parts or moving gauges? So what kind of gauges are suitable?

Workpiece processing: how to do after the parts inspection? Unqualified parts are scrapped or reverse? Is there a series of necessary conditions?

Tool material and finish machining quality: can the parts be compressed? Is it easy to scratch? Many standard gauges can be modified to avoid these effects. Have you noticed this point? (EN10204-3.1 、DIN ASTM GOST GB JIS ANSI BS)Approved metal companies near me Manufacturer

Manufacturing process: the machine or tool extrusion parts of the finishing surface, will make the parts become irregular, you choose the meter will take into account these?

Funding: what’s the price of your meter? How much is your budget?

When you start a test task, you need to confirm what kind of measurement you choose, and all of these factors are very important, they can help you to define as much as possible, to narrow the scope of your choice, convenient for the final choice
