Nope. My goal is to make them give the same results. Standalone is reduced in a way that it lacks the tool database. But it has safety limits on main things like HP, torque and such. That may be the reason results are slightly different. I will check it again and report back. Thanks for telling.

Yep i have chip thinning enabled on my own calculator I tied putting good calculations into my DB but then found out that 90% percent of them are almost dead-on at 150% feed override anyway. I still save data for different tools though- save me a lot of typing. check it out, both the online and slightly reduced standalone versions are free, might even like it BTW do you mind if i include data from your library into my online calculator?

I am getting something like that at mediocre aggressiveness: and really aggressive: Info from here: http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=48655

There is no 0.080" dia 2.0" long carbide drills around. Might have to use a HSCobalt drill with some sort of PVD coating like AlTiN or something. Or maybe a brazed carbide tip.

How does that look like? http://www.zero-divi...d_tool_id=43757 For the same 5/8 dia., 5 flute at 1.25" DOC and .044 (7%) on 17-4PH i get this at 150% chipload (you could call it manufacturer - recommended aggressive level) SFM=794, IPT=0.00589, RPM=4853, FEED=142.93 DOC=1.25, WOC=0.04375 = 7% = 31deg MRR: 7.8 in^3/min HP: 9.4 Torque: 121.82 in-lb Breaking Torque: 231.58 in-lb Cutting Force: 389.84 lb Tool Deflection: 0.0021 in Max Tool Deflection: 0.0025 in Looks close to their tool deflection is a little too close to breaking point than i personally would like, but hey. i am not saying their tool will fail....just might

That is quite impressive Was it a 5 flute? how deep per pass? 0.060 per pass is quite agressive. 140 IPM at 5400 RPM for even a 5 flute seems to be exceeding manufacturer-recommended chip thickness by 50%

Nope it is not like P20 P550 is a Very difficult to cut stainless steel I actually never head of it before. But it is very close to 17-7 PH stainless. So the SFM should be way below that of P20 I have just added it to the material list Here is the calculation with correct material http://zero-divide.n...d_tool_id=43495 for 5/8" 5 flute carbide TiAlN coated HPEM 1" doc and 0.020 stepover starting S/F are: SFM :150 RPM: 900 IPT: 0.004 Feed:18 IPM At this stepover SFM may be increased to 150-170% at a cost of shorter tool life May i ask you to come back and tell us how it worked. Its an exotic material and not many people ever get to machine it

Anyway. I have just released a Windows version of FSWizard that does NOT require internet. Check it out here http://zero-divide.n...age=FSWizard_SA Its right now a bullet-proof beta but lacking Manufacturer and user tool database. The results its giving out are identical to online version.

Thank you. Do you have any suggestions? Would you care much if i added some sort of MasterCam integration where FSWizrad takes the tool data directly from MC and then automatically updates the Speed and feed without a programmer having to copy-paste the numbers (Most likely this can be done one way or the other) Do i need to add turning and boring?

Hello, My name is Eldar Gerfanov. I am a programmer/machinist with a big company specializing in aluminum blow molds, and everything that comes with it. I decided to drop by and introduce my free online speed/feed calculator. http://zero-divide.n...p?page=fswizard It is designed to take out most of the guess work programmers and machinists alike face every day selecting cutting parameters. Unlike many it does not cost a dime to use. And its the only one of a kind that is web based, so it does not need installation and can be used from any internet connected computer or PDA in the world. I use it myself every day and constantly improve on it. Currently It calculates speeds and feeds for drilling,reaming and milling only. It account for Axial and Radial chip thinning, length of the tool and size of the cut. Conventional and HSM speeds and feeds are competitive or exceed with most of the tool manufacturers' data. All basic tool and workpiece materials are supported. There is also a tool database that allows registered users to save their calculations and create online tool library that they can access from anywhere. The same library can be used to automatically filter for User defined or Manufacturer recommended data while you fill up the tool information. Basically i am writing here because i am currently developing a more advanced Windows-based application that i am planning to integrate with MasterCam. So i would like to invite you to try my online software and give me a hint what you would like to see implemented. Both online and Standalone versions are ultimately going to have the same functionality and be sharing the same online tool library. Thank you. Waiting to hear your thoughts on this project.Hopefully i don't get banned for this as what i am doing is not commercial
