Guide
Paste a Fagor 8055 or 8060 ISO program and see it in 2D and 3D, with cycle time and warnings before you cut. The simulator recognises the Fagor dialect on its own and draws G68/G69 roughing with its passes, even when the profile is written after M30, as shops usually do. The page opens with an 8055T lathe bushing: facing, G68 roughing with a finishing pass, a groove, a pecked centre hole and parting off.
G68 (roughing on the X axis) makes its passes along Z, like turning; G69 (roughing on the Z axis) makes them in X, like facing. The simulator reads the profile between the S and E labels, applies the C pass depth, the D safety distance, the L and M allowances and the finishing pass at feed H, and draws every pass. In G68, S is the profile label, not the spindle speed: the simulator does not mix them up.
It detects the dialect from what only a Fagor writes: (MSG "…"), P100=… parameters, (RPT N…,N…), (IF … GOTO …), (CALL)/(SUB)/(RET) or ORGX. That way it does not flag 8055 G codes that mean something else on a Fanuc.
On a Fagor, G70 selects inches and G71 millimetres; on a Fanuc lathe those same numbers are finishing and roughing. And G68, a coordinate rotation on a Fanuc, is a roughing cycle here. When you move a program from one control to another, this is the first thing to check.
On a Fagor the rpm limit for constant surface speed is set with G92 S…, not with G50 as on a Fanuc. The simulator applies it when it works out the G96 rpm at each diameter and, from them, the cycle time.
On the lathe it draws G68/G69 roughing, G00 to G03 moves and T… D… tool changes. On the mill it simulates ISO moves: rapids, linear and circular interpolation and tool changes.
8055T G86/G87 threading and G88/G89 grooving, 8055M canned cycles (drilling in Fagor syntax and G87/G88 pockets) and the instructions in brackets (RPT, IF, CALL) are read without errors but not executed yet. If your program relies on them, the drawing will not show those operations.
It adds up cutting and rapid moves by tool with the real G96 rpm and the G92 limit. It shows which operation takes the time, to quote a job or decide what to adjust before the batch.
Frequently asked questions
Yes, this one. It runs in the browser, free and with nothing to install. You can try it without an account, and with a free account you work full screen and save your programs. The program is simulated on your computer, not uploaded to a server.
It is the X-axis roughing cycle following a profile: the passes run along Z, like turning. X and Z are the start point, C the depth of each pass, D the safety distance, L and M the X and Z allowances, F the roughing feed, H the finishing feed (H0 = no finishing pass) and S and E the labels of the first and last profile blocks.
Both rough along a profile with the same parameters. G68 (X-axis roughing) makes its passes along Z, like turning (Fanuc G71), and G69 (Z-axis roughing) makes them in X, like facing (Fanuc G72). The simulator draws the passes in the right direction.
Because several codes mean something else: G70/G71 are inches/millimetres, not finishing/roughing; G68 is roughing, not rotation; S inside G68 is a label, not rpm; and the rpm limit is set with G92. This simulator recognises the Fagor dialect and reads them the way an 8055 does.
Yes, as shops do: G68 calls the blocks between S and E wherever they are, after M30 included. The simulator runs them as a subroutine and goes back to the start point at the end.
Not yet. It draws G68/G69 roughing and ISO lathe and mill moves. G86/G87 threading, G88/G89 grooving, 8055M canned cycles and the instructions in brackets (RPT, IF, CALL) are read without errors but not executed yet.
For their ISO programs, yes: G00 to G03, G68/G69, G92 S and the same structure as the 8055. Instructions specific to those controls that are not ISO are not interpreted yet.
Yes. Under G96 it works out the rpm at each diameter within the G92 S limit and adds up cutting and rapid moves by tool. It is an estimate: it does not count acceleration or stops.
