Your control will give you an alarm “End Point Not Found” which makes sense because it can’t find one. It’s like the pot of gold at the end of the rainbow.

So you should now begin to work out why you get an alarm when the radius is too small. Your two arcs just don’t cross. In other words you are trying to fit an arc between two point that simply miss one another.

Stone fabricators often use tools with a 6 mm or 10 mm cylindrical shank, therefore 6 mm and 10 mm diameter ER collets are those most commonly used.

The Titans of CNC academy tool kits contain advanced carbide tools by Kennametal to help educate students on how to machine comfortably on the shop floor.

Anyway one really good simple way to use I and J is for a full circle. Oh and it’s bloody easy. That is once I’ve explained it to you.

Aug 5, 2014 — I want to put a 'cancel' button on the interface and whatever the process in question is running to cancel/abort/stop it from proceeding further.

There are many parameters to consider when choosing a turning insert. Carefully select insert geometry, insert grade, insert shape (nose angle), insert size ...

We offer top quality Solid Carbide Thread Mills and Hard Milling Thread Mills, which are outstanding in performance at unbeatable prices. Buy now!

At the CNC Training Centre we don’t get too excited about I and J when it comes to programming circles. That’s because you don’t need to worry your pretty head about it anymore. You almost never need it.

So there you have a fantastic way to programme a full circle without having to break it down into two halves or be clever like a newsreader or some twat off mastermind.

It consisted of a series of plastic gears. You stuck your pen in a hole in the gear and rotated it around another gear. With a bit of practice you could make some really nice pictures. Kept us happy for hours. The crime rate dropped dramatically in my area when these things came out.

I had this really nice guy phone me from Africa the other day. He explained to me that he needed to get his inheritance of 10 million pounds out of England and if I helped him he would give me £20,000. All I had to do was give him all my bank and credit card details. Oh and a small one off payment of £1000.

So in a full circle your endpoint is the same as your start point. There are millions of circles the computer could pick. It would be just like the shapes above. If you do the compass trick you will see what I mean. That’s why it’s impossible.

Where these two arcs cross it places the point of the compass. Now it can strike an arc that touches your start point and your end point.

ER collet clamping systems are widely used in all machining sectors and extensively for straight-shank diamond tools. The ‘ER’ numbers are loosely associated with the diameter of the interchangeable collets, measured in millimeters.

What’s this to do with CNC programming you ask? Well if you tried to use end point and radius for a full circle this is what you would get:

For boring bars Ø 16 mm and bridges. With internal coolant supply. LSCX = Boring depth. Scope of supply: without boring bar, bridge and insert holder.

I gave him my 96 year old mothers phone number because I thought at least she can benefit from it all. Her name is Mary so he couldn’t shorten that. She only has £1200 in savings so it would be doing her a massive favour.

The ER Collet “diameter” refers to the diameter of the tool shank (tool-shank diameter) which the collet is designed to accommodate, which may vary from 3 mm up to 30 mm. This is the diameter of the diamond tool that you can use (tool shank diameter)

In the old days I and J was the only way to programme an arc. You would tell the control where the centre of the circle is and the endpoint. This is cumbersome and a bit tricky. That’s why I’m not telling you about it.

How do you calculate speed and feed? · Speed (RPM) = (Surface Feet per Minute x 3.82) / Diameter of the Tool · Feed Rate = RPM x Chip Load x Number of Teeth · RPM ...

You can do it but you would have to break it into two halves. I’m not going to explain anymore because this method is for wimps and peole who can’t be arsed to read my articles.

Well yes almost. You could programme forever and never bother about using I and J with G02 G03. So just go off and watch some porn for awhile and I will explain to the real programmers when you can use it.

They both work the same way. On a modern control you programme the endpoint (an XY figure on a milling machine) and the radius you require.

On a Fanuc or Haas control G02 G03 are the two G codes we use to move around clockwise and counterclockwise circles. You don’t need the leading zeros so from now on I will call them G2 and G3.
