Then modify the post to output the depth + your variable, you check the drills on the comparator anyway. Part of the setup would be to input your variables for the drills.

When choosing the right cutting parameters to run, most people focus on the speed  which relates to the machine RPM.  This is a mistake!  Focus on on the proper feed per tooth (FPT) first, and then adjust the speed.  Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.  Chatter is nothing more that part vibration or noise, because the tool is not cutting properly.  Usually, the first response is to slow the RPM and the chatter will go away.  This often works, but this is unproductive.  What has just happened is that by reducing the speed and keeping the feed constant, the FPT has increased.  And most likely the FPT before was too low in the first place and that was what caused the chatter.

Mayday, I totally disagree. The depth of the point is not held, its the depth of the diameter. We measure the tool on a comparator now to get the tip info and then make the lg comp and the hole is dead nuts first part

The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed)  and IPM (inches per minute or feed rate).  We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.  Certain high performance mills have very specific running parameters relative to their material families.  We have listed these also as individual recommendations by coating family.  These documents are downloadable in pdf formats by clicking the links below.

If the variable was there, it would get you way closer than without it. The regrind is a good point but it would still be accurate if the grind was the same as the original (and it should be) for us, we dont use regrinds for many reasons so this would not be an issue.

I find myself adjusting the spot drill depth at the machine a lot. It would be nice to be able to have the code come out perfect. I dont see how this is possible though with the variation in the tools being used. especially drills and spot drills and regrinds ect...Like you said you would have to use comparator for each tool.

The speeds and feeds formulas are in the bottom of the charts below.  If you follow these guidelines, you will have a much greater success rate in part programming, and you will be milling more efficiently.

We produce very tight tolerance parts and parts where every feature requires inspection, probably like many of the forum members. In the last few months, I started using the chamfer tool type to define my spot drills so I could obtain the correct diameter of the spot (since the chamfer type has a variable for the tip flat). In many cases we have drill depths that are +/- .005 and since MC does not have a variable for the tip point we often need to make substantial length compensation in the control. I find that one drill to another (same tool, same manufacture) this value is consistent which is no surprise to me and I am sure no surprise to you guys.

4.5π(8500) / minute = 38250π inches / minute. Now we just do some unit conversion. (38250π inches / minute)(minute / 60 seconds)(feet / 12 inches) = 425π/8 ft/

Oct 8, 2020 — What drill bit should I use to cut through stainless steel? ... To drill through stainless steel, you need an HSS (High-Speed Steel) drill bit.

I am in full agreement here. It would make life much easier. It might be easier if the field was just tip height. So we could all run out and measure tip to full diameter length. All we would need for inputs would be tip angle and tip length.

shouldnt matter Dave, holding +-.005 is done at the machine. Drilling to an inch deep is -1.00 in code no matter what type of tool. measured in the machine correctly it will go -1.00

The tap is a tooled steel and much harder than the steel than it is threading. You will damage the surrounding threads and will need to replace the steel.

G, yes as I stated I use this for spot drills. I guess I could use it for drillls too but I dont know if other issues will arise. BTW, it makes searching for tools in the library a challenge.

We have created an excellent speeds and feeds calculator which incorporates these charts into the calculations.  It generates ranges of SFM or SMM and allows you to decide what SFM is appropriate.  It then automatically calculates the RPM.  Then it gives you a range for FPT and allows you to decide what is appropriate.  Then it automatically calculates the IPM or millimeters per minute (MMPM).  Try it out!  It is easy to understand.

Note:  These cutting feeds and speeds charts work with Accupro, Niagara, Data Flute, SPETool and all end mill brands.  We will have all of Harvey Tool speeds and feed charts loaded soon.

Doesn't the depth calculator have an input for flat on tip? I understand that having the variable in the tool definition is ideal, but I would think that you would be able to nail your tolerance with this, especially if you're measuring the flat with a comparator. My 2 cents...

It’s great to have drill tip compensation, however, the drill definition lacks a very important variable, the fact that most drills don’t come to a sharp point due to the drill geometry.

There is no difference between using a macro variable and a simple tool length wear offset. The real point is, if you can properly define the tool then this will not be needed.
