Thread Gauge Calibration - What Should You Know?

If you are using thread gauges or thread ring gauges you would have already heard about calibration. If you do not pay attention to thread gauge calibration then the integrity of the thread gauges you are purchasing and using could be compromised. In case you do not know what is thread gauge calibration and what is its significance then here are a few important factors that you should know about calibration.

When you order a custom trapezoidal thread gauge or a custom Whitworth thread gauge or for that matter any thread gauge, how will you know that it is exactly matching your requirements and specifications? As you know the thread gauges are inspection tools and unless they are 100% accurate there is no use having a thread gauge. When you calibrate the thread gauge you will know whether or not the tool is true to its specifications and whether it matches the required specifications 100%.

It is important to get calibration certificate along with your thread gauge when ever you are purchasing your thread gauge. All the manufacturers will arrange for a third party calibration certificate if you inform them early enough while placing your order. This may have an additional cost but you cannot avoid this cost because without having the confirmation that your thread gauge is delivered as per your requirements, you cannot confidently check the components that need to be inspected with your thread gauges. If there is any issue with the thread gauge you will think that there is something wrong with the threaded components. As a result, you would keep rejecting those components when the actual issue is with the thread gauge you are using. All such issues and mistakes could be avoided or minimized when you go for a calibration certificate when you are buying your thread gauges.

You may need to go for recalibration every time you repair your thread gauge or make any modifications to it. In case you are experiencing sudden episode of issues with your threaded components then it is best to first check the thread gauges you are using to ensure that the problem is not with the thread gauge.

It is also important to get a calibration certificate for your thread gauge if the tool has been dropped or if someone that is not trained properly use the thread gauge and exerts undue force. In other words, whenever you suspect that the thread gauge could have been damaged then it is vital go check the thread gauge and calibrate it so that you can be sure of the accuracy of the thread gauge.

Always source all your thread gauges from the most trusted companies. Whenever you are calibrating your thread gauge get it done from a reputed calibration center. You cannot afford to have a faulty thread gauge as it is an inspection tool, a standard that is used to measure the accuracy of the other tools. Therefore, make sure that your thread gauges are always well maintained and regularly calibrated.

Java: How to Get Keys and Values from a Map

Introduction

Key-value stores are essential and often used, especially in operations that require fast and frequent lookups. They allow an object - the key - to be mapped to another object, the value. This way, the values can easily be retrieved, by looking up the key.

In Java, the most popular Map implementation is the HashMap class. Aside from key-value mapping, it’s used in code that requires frequest insertions, updates and lookups. The insert and lookup time is a constant O(1).

In this tutorial, we’ll go over how to get the Keys and Values of a map in Java.

What Are Garbage Collection Logs, Thread Dumps, and Heap Dumps?

Java Virtual Machine (JVM) generates 3 critical artifacts that are useful for optimizing the performance and troubleshooting production problems. Those artifacts are:

  1. Garbage collection (GC) log
  2. Thread Dump
  3. Heap Dump

In this article, let’s try to understand these 3 critical artifacts, where to use them, how do they look, how to capture them, how to analyze them, and their differences.

1. Garbage Collection Log

a) What Is a GC Log?

GC Log contains garbage collection events related information. It will indicate how many GC events ran, what type of GC events they are (i.e. Young GC or Full GC), how long each GC event pause the application, how much objects did each GC event reclaim.

b) What Does a GC Log Look Like?

Sample garbage collection log file can be found here. 

c) Where Are GC Logs Used?

Garbage collection logs are used to study the application’s GC and memory performance. It’s used to optimize the GC pause times, it’s used to identify optimal memory size for your application, it’s also used to troubleshoot memory-related problems.

d) How to Generate a GC Log?

You can generate garbage collection logs by passing the following JVM arguments:

For Java versions until 8:

Java

xxxxxxxxxx

1

1

-XX:+PrintGCDetails

2

-XX:+PrintGCDateStamps

3

-Xloggc:<file-path>
