I used to do profiling but you need the setup and labour time to carry it out. The serrated cutters were more than £10 a pair last time I bought them prior to retooling they lay in the cutter library and are turned out from time to time, the tips are cheaper and manufacturers like Whitehill keep your custom profiles in their computer and all you need do is reorder. Same goes for custom Router tips, the makers will do this for you as the CNC Router has need of specific shapes and left and right hands.
The point is that we now as an industry are minimilising our staffing compliment and competing with Poland in supply of timber products and there labour costs not to mention timber prices. The Russian timber market were moving factories from one place to another as timber declined where they were, they are only limited to where the train tracks run so moving to virgin ground around the factory is efficient method of harvesting.
We need the machines to run efficiently and cost margins are important. So need, unless you are specializing in supplying custom moulds is not realistic unless your a small specialist and the market was not prepared to buy at the cost needed to turn a decent profit I considered worthwhile. Everyone was running set moulds or shapes and the tips are easy setup and no need in some cases to take of the machine. That was my experience and the outlay to make Grinding work efficiently was rather a lot, I looked going the Weinig Route with Rondomat and CNC profiler and that would be a about £50k+at the time I looked for full auto on the grinder save labour time. I did have an old Weinig Rondomat after replacing a old Wadkin but it was not auto and kept a a man busy. It still is in the old Tool Room and does straight sharpen on our Planer heads and if I need to do a custom mould for Spindle or 6/5 Cutter.
I visit some of my timber suppliers from time to time and the Saw Doctor seems to be a thing of the past and they are even promoting through away router bits as they can be purchased very economically. Gone is the in house Tool room and they send away for sharpening like me or utilise tips technology whenever they can.
