I need some help understanding the concept of "NURBS Interpolation " and how it can help reduce cycle time. Would appreciate your inputs on this topic. Regards, Sai

We have a Haas GR510 router in our shop. I would like to design some setup sheets indicating how the workpiece must be clamped on the tabble and whattools should be used. Would appreciate inputs regarding this. Also it would be great if any of you have some sample templates or smaple sheets outlining these information.Would be a good way to start off with.

Is there any software that can generate cultist, Bills of material from AutoCAD drawings? We currently use AutoCAD, and do all our drawings in 2D. Our product line consist of Architectural l railing, louvers and grills.

When using the drill option on Mastercam, I notice there are some options like Peck Drill, Drill/Counterbore etc. I understand what these option do, but would like to know how each one is diffrent from a machining perpective. In otherwords when would you use peck drill viz. Normal drilling cycle. Which one has a better dimensional accuracy and finish.etc.

I am having all kinds of problems Tapping. I have to Tap a 5/8-18 Tap in Carbon Steel ( not very hard). First of all when I used the recommended size drill bit 37/64 I find that the holes a bit too big. Then I tried 9/16 which seems to work ok. But since I have to thread 1 inch deep guess I am facing all the problems. I am using a Cleveland Twist Drill co Tap for through holes, where the chips seems to be pushed down. Some holes are tapped ok, but in some holes the taps looks bad, and the Tap gets struck in the hole and machine stops . Would appreciate if someone can enlighten about the do's and donts of Tapping.( especially deep holes) P.S Machine used, HAAS Vertical Machining Center

once again thanks for your response. By doing the Ramp instead of plunging , I surely save time. I guess I would use this method when doing slots. I have 6 more plates each 3 x 6 steel plates with 180 slots on each one of them. Do I first use a Rough End mill one size smaller say 3/8 and then use my 1/2 inch end mill to finsh to shape. What kind of rough end mill would be ideal. Are they any dos and dont when using a rough end mill. Should the feeds and speeds be slower with a rough end mill as the depth of cut is considerably large?? Regards, Sai

Thanks guys for your quick replies. I have the following questions, 1. How is Ramp diffrent from just countoring with depth of cuts. 2. how do I do the Zig-Zg option in countoring, do I need to select Pocketing instead of Countoring for Zig Zag option. If so can i pocket a 1/2 wide slot with an 1/2 inch end mill. 3. I plug with the End Mill, should I first drill some holes along the slot and then Mill ??? Would appreciate your thoughts

I have to machine a 3feetX 4 feet cold rolled steel plate , 3/8 thick . Have to cut out 90 slots all the way through, length of slot about 7inches. The width of the slot is 1/2inch. I used a 1/2 inch solid carbide end mill , Feed= 7.5 inch/min and Speed= 1500 rpm. I am machining it on HAAS Router machine. When I programmed in mastercam I got the machining time as 18 hours. I drew a line at the middle of the slot width and used the countor option toolpath. Used muliple pass with depth of cut = 0.05. Is there a way to optimise the process and reduce the machining time. Are my speed, feed and depth of cut right?? Would appreciate your valuable feedback. Regards, Sai

We are currently having an issue related to hole sizes, for our picket panels. The commercial tolerance for the OD of the picket ( 1/2 inch round pipe) is +15000 and - 30000. We have experinced that when we change the hole size by even 2000 the pickets dont fit well , either too tight or loose. Is there a way to determine an optimum hole size for a material with such wide tolerances. Should we use some statistical tool to determine the mean of a sample of the pickets and use that as our hole size??? Would appreciate your thoughts on thsi issue.

I have the alloy. Just want to know how to get the process working

We have to radius a thin walled Aluminium channel. Has any one got some information regarding how to bend tubes and pipes by encapsulating them in some low melting point alloy?? The reason I have to encapsulate is the channel deforms when we fill it and radius. Its T5 Aluminium with a wall thickness of 0.08" The problem we are facing is what kind of mold material should I use to encapsulate. In other words I need some reusable mold ( becoz I have to ben some 700 pieces) in which I can put my channel and pour the alloy to encapsulate. Is there a particular material with which I can make this mold???

what is 3.82 ?? What will the formulae be for AL ans Stainless Steel?

Brenden How did you calculate the speed and feed. Is there some kind of formulae???

The hole size I drilled is Size M i.e 0.2950. Hope it is sufficient
