The 0.5" Ball Nose bit is machining into the surface 0.125" during a fluting operation. BUT... the toolpaths overlap and where the juxtapositioned paths meet there's additional material removed while machining the ridge apex. Does that make sense. I've never mic'd the depth so I can't get an exact figure.tonydahose wrote:How sharp/high are the ridges on those scales? Does it feel like the PPT? Are there any other patterns that you have, maybe some dimples, like on the tuff. It be really cool if you could put the :spyder: symbol instead of the simple circle dimples but I am guessing that you would need permission. Who knows maybe spyderco will do that on some of their stainless steel handled knives.
I've never held a PPT so I can't comment on the feel...!
I've got LOTS of patterns... not all of them have been milled for an actual knife though...
Registered Trademarks are usually well protected by their respective companies...! Using the Spyderco :spyder: on a product would most likely result in a cease and desist order or worse...!!!

Now I need to develop CAD/CAM machining files for a Spyderco Endura FRN 4... the nylon scaled version having the nested stainless liners. I have never attempted indexed double sided machining but I felt it was a skill worthy of the effort.
As with the G10 version of the Endura for the scale creation I needed to scan various parts of the knife and import the scan data into the CAD application. Once that was completed I created various machining paths and operations to produce the end product. With this knife... another small Anso patterned set of scales.
The first two pics show a screen shot of those machining paths AND a PREVIEW image of what those operations will produce.
The most difficult part was that I had to think and visualize both sides of the scale at the same time. The outer face of the scale receives the texture fluting and the inner face gets a pocketing operation to receive the nested stainless liners.
Once the CAD work was finished I began with the reverse side pocketing operation. I machined the liner pockets. The G10 material was indexed using four .25" holes drilled as a first operation so that the doubled sided machining would perfectly register when the G10 was flipped over. If you look carefully you can see the four holes at 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock.
The G10 was flipped and the outer face machining was performed.
The result of all those machining paths and operations is this... a set of nearly completed G10 scales with a small Anso pattern...
Once the scales came off the machine I evaluated the results and determined that a few tweaks were necessary. I made a few notes... modified the CAD files accordingly and moved on.
