It would be useful to know what type of job it is, ie what size ? Does it need 5 Axis ? Are there multiple tool changes involved ?
I have a drawings in .pdf. perhaps it will be more useful. I believe it need 5 Axis. Because I'm new to CNC i am here to look for some help.
You will need 5 axis for the best job. Is the material MDF ? Can you PM me quantities and a target price ?
It should be walnut wood. 50 pieces, 25 right and 25 left pieces
I like walnut, I used to make harps from it. I'll send this link to someone I know with a suitable machine, they might be prepared to do it.
It could work out expensive.Fixturing for both sides means an amount of work before the first useful part goes near the machine plus the tapered surface is a fairly demanding starting point.Then you have a 3mm radius on all corners plus the stipulation to break all corners 0.3mmX45 deg.Its actually the sort of job that wouldn't be hugely difficult to create most parts of with an old fashioned overhead router and a pin guide,followed by a hand router on a jig to create the angled surface.Having a CNC to make the jigs would be quite useful.
As an aside,the two side views reduce the clarity of the information,one ought to be flipped laterally to convey that the side faces have differing pockets at different depths.I also don't see any information about the bevel to be applied to the sloping face,is it a constant angle or is there a twist?Given the need for 25 pairs and the possibility of knots,sapwood,other blemishes and chipping out I would make an extra 3 to 5 of each hand but I'm not interested in the job.I suspect that anybody who is will price the parts quite highly because of the factors I referred to.
Excellent advice from Routalot. When machining walnut it's often necessary to use lh and rh tooling to avoid chipping off corners. I imagined a first side op to machine the shallow pocket and half drill the through holes, then flip the part onto a fixture that locates in the pocket and machine the second side and tapers and finish the through holes.
As you say, not cheap.
Routalot, you clearly have a lot more experience than I do, I'd value your views on pricing such a job.
I'd price it into the stratosphere.First of all there is the challenge of sourcing the material and I'd order at least 30% more than the bare minimum because of the factors I mentioned earlier.Then there is the time taken to actually decipher what the items look like as the pdf posted lacks quite a bit of information,such as the overall height of the piece and the bevel to be applied.A step file would probably be an advance.Quote:

Add up the time to think the job through,design and make fixtures before making a single part,include both machining and finishing time and the cost of disposing of couple of dustbins full of walnut flakes and then add a working profit margin.Then wait for the gasp on the other end of the phone when you announce the final figure.......
Worth sending your enquiry to total machining solutions [email protected] where I work. I cutbsome lovely Oak panels last year for a film job and we have pcd tooling which cuts wood well. Never machined walnut but every day is a school day
