    Stone material for stoning aluminum alloys

    Hi all, I am in search of some intel on what material stone I should consider buying for stoning aluminum. Arkansas stones have a tendency to clog. The gray norton ones work well but are potentially a bit aggressive on the MRR. Any good middle ground?

    What is the deal with Inconel

    Over the past year or so I have been machining a lot of super alloys. Initially I thought "oh god this is gonna SUCK" But after awhile it really is just like....okay this is another material to cut. Maybe it is because I have had to cut such a wide spectrum of materials over my career but I...

    Learning Hypermill

    Hi, I will be starting a job that will require me to learn Hypermill. I am moderately annoyed by this but also excited to broaden my skillset as well. I have about 8 years of Mastercam and 4 years of Multiaxis experience under my belt. With such a solid base I expect I will be able to handle...

    SAE Porting in Inconel

    Good day, Has anyone here got experience with O-ring boss porting using Inconel 718? Job coming up is going to require a bunch of SAE ports in this lovely material and was wondering what your thoughts are. My only experience using form ports is exactly zero. I assume a carbide tipped SAE form...

    Cost of large 5-axis mills

    Good morning, I had the pleasure of touring a shop that had some super large 5-axis machines... I was just curious what a ballpark $ amount might be for such a machine? DMU 125 for example, or an Okuma MU500-V, or a Doosan DVF8000T. I would guess a DMU125 (EDIT DMU 125 P Duoblock) is like...

    Sandvik acquires Cambrio (GibbsCAM)

    So I invested into SDVKY when I heard they bought CGTech awhile back…and I had no idea they acquired Gibbs until I was scrolling thru my Fidelity news feed. All these big bois buying up the small fries can be good for customers sometimes, but also bad in a lot of ways. Thoughts? Sandvik really...

    Mastercam 2022 Released

    My post is very straightforward for once! Mastercam 2022 has been officially released. I am pretty comfortable in saying this is the most substantial Mastercam release since Mastercam 2017 came out and changed the entire interface. For an analogy, the past few releases have felt like iOS...

    Hypermill vs. Mastercam/others as 5-axis solutions

    Hello, I had a long meeting with a HyperMILL salesperson today. It went well, and I would really like to see what others think of HyperMILL and how it relates to other popular software solutions like Mastercam. For the sake of this argument I am not considering other options that utilize the...

    Quality of Tooling/Tooling Systems

    Hello, Just curious on a topic. Tooling is expensive, yes? Well, I wonder why some brands sell very expensive tooling, and some companies sell much cheaper tooling. For the sake of argument lets take away the outliers like Shars and eBay on the low end, and companies like Big Kaiser or Haimer...

    Coolant Mist Collectors

    Hello fellow geniuses, I have had something in the back of my mind since I bought our machines a few years ago and that is COOLANT MIST!

    How do you choose tooling?

    Hey All, Our shop is always trying to maximize our value when we buy things. Right now I am trying to spend a healthy chunk of change to get our tooling stock back up to snuff. We also have a fixed amount to spend so there is always a compromise somewhere. How do you go about selecting...

    Renishaw probes just aren't worth the money...

    Also, Friday is the most overrated day of the week. OK OK I jest, but I had to get your attention with my ridiculous title. I had a sad day today, one of my fucking Renishaw part probes got a wee bit busted up. I'm setting up my 5-axis with a spherical part. So I setup my probing macro, I...

    Heat Treated Inconel machining

    Ohhhh boy I need to machine a fun part. It is a rocket fuel injector for a liquid fuel rocket. The initial part was made additively using Inconel 718, and naturally it was sintered in the oven, and then stress relieved during heat treating. So this shit is hard and tough. Rockwell 40-45. All...

    Aluminum swarf/chips processing

    Hey everyone, hope you're doing well. I am curious to see how other shops are managing aluminum shavings/swarf/chips. We machine a lot of different materials so we don't usually recycle. However for the past 3 months our machines have been processing A LOT of aluminum almost exclusively. So I...
