Had to create a special washer for the Alpha Racing gear shift linkage to ensure the gear shift arm won’t move on the splined shaft. The tab fits into a groove in the shaft. It’s amazing how things rattle loose with racing conditions.
Also using adaptive roughing in NXCam to see how hard/fast/brave I can push the PocketNC. Very happy with the machines performance with the amount of data that was being processed.
Appreciate the adapter file you shared previously. I’ll about to do a remix where I use low profile socket heads to lower the vice (evry mm helps!).
Interestingly there is also a 4x adapter out there for Syil X7 that is the same diameter without the pocketing which when I discovered on gfabcad there are 2 Paf54’s and one has different mounting hole alignments ………Anyway measure 1 2 3 times.
No problem once I verify with a quick print - waiting on some fasteners to show I ordered - I noted which is why I ended up doing a remix that the outer mo’s on your file do not line up with my Xi dian Paf 54 (ther’s also 2 versions both different baseplate designs on grabcad so going with the physical item I got of AliX
If you have material left on the sides of the rebate like I did I made sure to cut all edges in the same quadrant of the machine. Made it position accurate regardless of rotation position when the vice is mounted. I wanted to remove the slight rotation deviation of the b-axix
Hi
No problem to share but not 100% sure what you mean by cutting the edges
I’d mentioned previously there seems to discrepancies between some of the grabcad PAF 54 base plate holes
I’m basing my modifications on the xin dian vice of aliexpress
I designed my fixture undersize so I could use the rotation of the B axis to finish the rebate size exactly and remove any errors during the 3D printing process.
Cool work! It would also be cool to get some technical informations about e.g. tool type, tool diameter, plunging feed rate in full material,… I’m always fighting with vibrations in aluminum or brass.
Hi @WilWeber
HSS endmill. Super sharp, aluminum likes very sharp cutters.
Ramp engage @5 degrees full cut feed to open out an engage point. Used adaptive roughing in NXCam to clear out most of the material. Then single pass finish on all sides and left 0.05mm floor stock to push out the parts. I made two each having a different offset for the tab that engages the groove on the gear change input shaft. Options to ensure the arm doesn’t rub the casing.
I used FS Wizard to get the starting points for speeds and feeds. I went 9000 rpm at around 200mm/m by tweaking the settings listening to the cut conditions.
Hope this helps with future cutting.
Regards
TP
