Hello everyone As shown in the figure, assume that the hole size is .286, the datum B size is 22.441, and the datum C size is .99, Is the position of the hole apply to MMC equal to .01(hole)+ .01(position)+.01(datum B)+.20(datum C)=.50

Thanks a lot, very clarity.

Dear All We had encountered some problems on mill machine spindel deformation, parameter s below, could you calculate the axial & radial forece of spindel, tks. 1. RPM : 300 2. Feed rate : 700mm/min 3. Ap : 5mm 4. Ae : 125mm 5. Material : S45C

Dear All Do anybody know N80 L_FREI & N90 L_ZYM91 definition, what does is mean, thanks. N10 DEF REAL _camtolerance N20 DEF REAL _F_CUTTING, _F_ENGAGE, _F_RETRACT N30 G40 G17 G710 G90 N40 DM_MILL N50 CYCLE800() N60 TRAFOOF N70 TRANS N80 L_FREI N90 L_ZYM91 N100 ;Operation : FACING_1 N110 T1...

The material is SS41.

Dear All Due to the inner diameter (340 mm) of the bushing is required in the post-lathe process, how long does the liquid nitrogen shrinkage fitting installation need to stress relieve before precision machining to the finished size.

Dear All I have doubts about the differences between the two burner types, leap and rich burn, such as speed, fuel consumption, economy, maintenance, thank youhttps://files.engineering.com/getfile.aspx?folder=1d660521-22ce-47da-a0d9-14eb76cfc640&file=123.JPG

Dear All We encountered a problem about Siemens Controller 840D axis angle definition, as attached illustration, tool axis parallel to the X axis, how to rotate the axis -90 degree by Z then tool axis parallel to the Y axis, thanks...

Dear All I would like to ask the NX12 lathe method, how to program the Cycloid path as shown, thank you. https://files.engineering.com/getfile.aspx?folder=17581ada-d88c-4c3d-96a3-696b1ac25f8b&file=??.PNG

It supposed to GE spec, but not aviation, seems to energy or power specs.

Dear All We got a machine drawing of a quotation, the material shows "C50E56A", what kind of metal (Inconel 718? Carbon steel?), thanks.

Dear All What is the difference between INCONEL718 and INCONEL718PLUS manufacturing (lathe/milling) (eg rpm/feed/depth/machining time), could we use the same parameter for 718 to work 718 plus, thanks.
