Thank you for your videos Tom! You cover a lot of ground with just one video which makes these a very handy reference when I need to refresh what parameters are best.
Tom, you're the best. I learned on my own in the beginning -, jumping into mastercam and post processing making mistakes, correcting, but still continued to do steps I didn't need or wrong steps. Watched this video and made things clearer, and made more corrections. Gonna watch other of your basic videos like this to continue to improve, thanks for the post..
I am assuming and it might help others--that you do not keep the tool in contact with the material rounding corners (sharp)--so that the lines drawn do not confuse the viewer? Generally programmers will roll the tool around corners since you take your life into your hands when that cutter leaves the material and travels out into space possibly violating something on more complex parts
Can I ask anyone here and it's a bit of a naughty one but how can I get master cam free on my laptop. Am really wanting to get into it but can't seem to find anywhere to download it for free. PS Tom your a legend these videos are awesome and will be trying the bits out once I get the prg up and running
Hi.Great tutorial.I have question.I put in Fine Mill11 to use the diameter, but when I throwt the program it does not show D11.Where to turn it on? Thanks
I would like to see more videos on how to do tool paths on mastercam for the lathe ... also could you do a video on how to hand program radius and chamfer on lathe?. thank you in advance.
How can I do a slot mill on the middle of a part in the x and y axis so for eg lets say a 2x3 rectangle I want to cut a slot with a 6" diameter slot cutter basically the shape of the part is the female part of a clevis . v9.1 so in other words if the part is 2" thick I want to run a slot mill down the z-1" approx 1.5" deep it will be a .375" slot . Then I want to drill a hole from top as per normal but if possible using same slot cutter I would like to face the part top and bottom 1.25 " deep and a flat approx .75" wide It doesn't work holding part vertical with an endmill I tried it was horrible I have many of these to make they are for the door bars on a race car so a male and female clevis with a .5" hole through each . I will be using a 2000 vf2 Thanks so much Sir .
smusick1955 It all depends on the shape of the part that you machines on top. usually you machine the top shape into a jaw in order to remove the excess material from the bottom and then machine the features on that side.
I can chime in that for example in mold making you first put the block in upside down--exactly as in this video and machine the bottom and tapped holes and such--you then turn the block over using your chosen method for holding it on the finished walls--you then use an indicator on the finished walls to pick up center zero-- and lo and behold when you machine off the rough sawed top--the walls with match perfectly. After the block is flipped over if there is alot of material keeping you from getting in with the indicator its ok to visually mill it off so the needle is not trying to sweep under a huge ledge.
Prakash Sarasam S Pass CNC milling, basic 1400-1800 depends on experience, housing allowance 200, 8 hours a day and 1 week 1 day off, OT 1.5 times, can do programming.
Waylen I agree that you have to learn to code. I find myself troubleshooting programs all the time and the ability to find errors in the program is what makes you a CNC programmer. For the last 34 years I have worked and installed machines and every shop has had a CADCAM software they use to write their programs. It definitely depends on the complexity of the part of course but CADCAM software saves a lot of time and if you do any kind of 3D contouring you cannot justify hand writing code. Possible yes but not efficiently. Thank you for your comment.
@@TomStikkelman Yes,Editing and finding mistakes is much easier in basic g-code if the program is written that way.Too many shops, However, are using computer generated code in their programs making it very difficult to do anything with and it's all for the reason of hiring unskilled workers.Creating a disconnect between a good education and getting real world job using that education.
Waylen It’s hard for shops to find skilled workers. The only way to become skilled is to work in a shop for years and not just as a button pusher. Many shops struggle to find skilled people. The education system is not helping that
@@TomStikkelman Shops that never seem to promote from within have done much to create the problem,if it actually is a problem.Many doing the programming and leading the shops are under employed Engineers with 4 year degrees and more,Not really Machinists at all,The industry is a mess.My local community college just announced they are teaching Mastercam to get kids interested in going to school for the career.Yet, when they graduate and realize how few jobs there are in that that specific area they get discouraged and leave the low paying button pushing job they have..There isn't much of an opportunity for someone from the shop floor to work their way up.
Waylen That is true. The operator really has to do things on his or her own to advance. It takes a lot of ambition to do that. Thanks for your feedback. 👍
