1. So, as you already know, choosing the correct or 'perfect' tool for a job is not always a walk in the park. There are so many factors to take in. Material, tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material, and so much more. So how do you do it? 

Well for Carmex Tools specifically, they have designed an intelligent tool wizard. You put in a few details and within 1 minute you have the exact tool you need and the CNC programming, speeds & feeds and all the other details to go with it! 

For todays example, we will be finding the perfect Carmex Thread Mill.

2. After selecting Milling, you then have to enter in your basic requirements. For this example, we have to choose the thread type; Internal (Blind hole), Internal (Through hole) or External. 

After selecting 'Internal (Blind Hole)', you then have to choose the Thread Profile, (I have selected ISO), and the pitch (0.4mm). It then gives you the available Standard option, which for this was 'M2 X 0.4 Coarse' . 

I then selected the length as 4mm.

3. After entering the basic requirements, you then have to select the appropriate material. I selected Non-Alloy Steel and Cast Steel, Free Cutting Steel (Annealed ≥ 0.55% C). It then gave me a little description about the material I selected:

Steel (commonly called carbon steel), is a mixture of carbon atoms with iron atoms. Sometimes, other elements are added to the steel during the smelting process, making it an alloy steel. The added elements provide the steel with ductility and strength. Non-alloy steel has no elements added to it as it is smelted.

4. Now we have entered the basic requirements, and the material, we are ready to look at the tool suggested and the tool data. At this point, it will give you a selection of a few different thread mills which would be suitable for your application. You can then select each tool, analyse the data and select the best tool for the job. It will give you different variants suitable, for example HardCut Type, With Coolant, or Indexable. You can also see the product code, product images and 3D animations of each tool being used, to give you as much information as possible before you make your decision. The tool I have chosen is MTS 03016 C10 0.4 ISO MT7.

5. Now you have chosen the appropriate tool, it may, or may not bring up a warning. In this example, the warning states; 

'The spindle speed (N) suggested by the software exceeds 12,000 RPM.

You have two options:

  1. Either reduce your cutting speed (Vc), so that N (which is calculated from it) drops to a level below this threshold, or:
  2. If you believe that your CNC machine can handle speeds above 12,000 RPM, you can raise the above threshold via the Settings > CNC Defaults menu.'

6. This step is called CNC Post Processor. It is for basic CNC configuration, such as speeds, and cutting direction. You can enter in your desired cutting data, so that you can get accurate CNC programming data and accurate information for your application using the selected tool. You have the ability to select the Stability, Operation method (Right hand or Left hand), Vc, Fz, Tool entry (% of F), cutting hand and sometimes cutting direction.

7. Now all your basic CNC configuration is set up, it's time to complete the advanced CNC configuration, such as CNC control type. You can choose your program type, program name, units, number of passes & positioning. For the passes, it shows you updated diagrams of what you're selecting, as you select it.

8. Now you have populated the tool wizard with all the information you have, you are done. In front of you now sits the exact thread mill you need, with the exact CNC program. It gives you all the information you need to get the product code for the thread mill, and the CNC program to use that thread mill in your application, correctly to how you needed it. 

You can then print off the program, and it will be able to give you more information, such as how long it will take to thread mill 1 hole. You can then work out the cycle time of your application. 

Now you know how to use the Carmex Tool Wizard to find the perfect Milling or Turning tool, try it for yourself and see how amazing it really is!
