Roughing as it should be done (cnc milling)

[@CncFrezar]

Hi guys. This was such a simple job but an awful lot of mess. Now, after roughing, the part goes for hardening.

[@sicstar]

Yeah gotta shovel a ton of chips after that. Been there done that ^^ An good job turning the thing with the forklift and not the crane. A ex co worker of me once almost tore down our 5 ton ovearhead when he turned around a chunk around triple the size of that thing (and nearly exactly 5 metric tons of weight) And very nice to see some proper feedrates for roughing such a chunk :D

[@ChrisMaj]

You call this a simple job? Nicely done as always. 👍

[@paul5683]

People tend to forget how difficult it was to make something like this before cnc machining. Multiple men would be needed. One to machine out the main block. Multiple tool makers to make the different inserts, like corner blocks and the central form. All the inserts would have to have bolt holes and the main block would have to have matching bolt holes for fastening everything into place. That is after everything was ground to size after the individual heat treatments. Then hopefully everything was done correctly, that is the initial engineering and drawing to all of the individual parts being made correctly. Yes, something like this block could take a well supplied tool room a month or two in order to make. The good old days were a real pain in the ass.

[@wildin13]

A month or 2? From what I've heard that's bloody good going. I'm told maybe 2 complete dies in a year at a push. 5 years ago we knocked out 12 dies for Aston Martin prototypes in little over 6 months (we were working at about 150% though.. 🥵)

[@timholstpetersen79]

Nah. People don't 'forget'. Either they know because they've tried it, or they don't. I've worked with items this large (and larger actually) although in cast iron, which is a totally different story... both good and bad. The good is it's much easier to machine. Tha bad is it's hell of a mess ;-)

[@joezukas5398]

You anit shitting it would, and the next guy who gets it is thinking ah shit.

[@qwertyuiop2895]

Pretty clueless comment. This is simple mold done in so called "monoblock" (or "monolith") style, one solid block. Most molds are still done normal/classic way (many separate parts, inserts and so on). CNC (or not) has nothing to do with it. Yes, it was harder to do on manual machines, tracing etc. But knowledge and skills were higher back then among mold/tool-makers. Modern CNC guys often lack basics. Mold is "done", but doesn't work properly. Machining a mold is only one step. Then you have assembly/fitting, startup, trials, maintenance and repair (and "monoliths" are harder to repair).

In the right grade of steel we get up to 3000mmpm feed with around 580 to 600 spindle speed quite comfortably taking 2-3mm deep cuts at around 60-75mm step over. Investing in a right angle spindle head could also dramatically increase productivity when roughing the sides.

Ahoj pekná práca! Predpokladám, že sa jedná o oceľ triedy 19... Skúšali ste porovnať životnosť plátkov pri chladení s hydrolom/bez ? Viem, že teplo z miesta rezu odvádzate do triesky, len ma to zaujímalo aký by bol rozdieľ, či by to skôr zalepilo hranu na brite alebo by bol výsledok cca rovnaký. Neviem či ste teda používali chladenie vzduchom (cez hadicu alebo priamo cez vreteno?) Ešte sa spýtam aký uhol zanárania a o koľko bol nižší posuv pri zanáraniach do materiálu pri tej 35tke fréze, ktorá bola v 6tej minúte. Na to v akom dlhom upínači bola upnutá, sa zanárala teda veľmi potichu (žiadne pazvuky)

[@CncFrezar]

Ahoj dík. Pri hrubovaní vždy používame vzduch a na tieto plátky sa aj nedoporučuje emulzia. Je to lepšie aj preto že ich odfukuje preč. Skúšali sme aj emulziov plátky od Iscaru ale životnosť sa nijako nezlepšila. Fréza sa zapichuje po uhlom 5 stupňov. Tieto plátky od Palbitu sú výborné na nekalené mat a na slabšie mašiny. Majú trochu ostrejší uhol čela tak idú aj potichšie. Na kalené používam radšej Pokolm.

I miss machining steel I only machine Pure copper at my job, any particular reason you don’t use coolant?

It's not. Side milling is almost always the fastest way for removing material. Tool wear is about the same.

[@3DMeister]

@@paulgrosfeld5297OK. Less load should be a better cut which results into longer tool live and/or a faster cut. Since you cannot drill full holes to remove all material it my need a special strategy , so I understand to do it the conventional way. It would be interesting to compare both in mass production. My thoughts.

Why not rough out with a 315mm 45° indexed face mill, mid rough with D50R0.8. Then use a bull nose end mill to finish it all off, maybe append another finishing pass with a new tool for very tight tolerances? This looks like a job we could confidently cut the machining time in half.
