3 Tips for Faster Rapid Prototype Machining

Time is money …  even more so in rapid prototype machining. Rapid prototype machining is important for bringing a design to reality. While making usable parts, this process also allows for testing and evaluating the design. In the consumer electronics industry, time is also crucial for beating fierce competition to market with the newest products. So, I’ve come up with three tips to help you become more agile and your rapid prototype machining faster.

1. Standardizing Stock Sizes for Rapid Prototype Machining

How many times have you stood next to a rack of material measuring to find the correct size stock for your part? One way to get past this is to have a library of standard stock sizes. If you have a dozen or so standard sizes, these can be saved in your CAM system to fit the size of the part needed. I personally would rather have a few more roughing passes to mill extra material then wasting time searching and cutting stock to size before milling.

Rapid prototype machining with standardized material blank sizes kept in stock will allow you to produce prototype parts quicker because you are guaranteed to have stock on hand.

Rapid prototype machining using standard size material blanks held in inventory can speed up the process and time to market.

 

2. Part Probing for Rapid Prototype Machining

Touch probes can save significant set up time. For example, with the 3D Probing on DATRON CNC machines, you are able to program cycles to find edges to set zero points. There is also an option to rotate your program to match the stock that was probed. Say you needed to put a part back on a machine to adjust a feature. With a probe you could touch off on a known location and reset your origin.

Rapid prototype machining can be made more efficient through the use of a 3D probe integrated on the CNC machining center. This diagram illustrates part location and verification.

3D probing can speed up rapid prototype machining in many ways (see above).

 

3. Optimizing Your CAM for Rapid Prototype Machining

How many parts do you make where you are always using the same machining techniques? Rough, finish pass, drill etc. Most CAM systems have an option called feature based machining. This option looks at the solid design model to define features that can be machined. Once those features are defined, the software selects toolpath strategies to machine each of the features found. Feature base machining might not be ideal in all situations but it will take significant time out of programming, even if you have to tweak a few parameters.

Rapid prototype machining CAM features like future based machining can be used to speed up programming and reduce overall prototyping time and even time to market.

Rapid prototype machining can be made more efficient by using feature based machining in the CAM software.

 

In conclusion, these three steps save you valuable setup time. I have personally seen this practice take a solid file to a metal 3D prototype part in the matter of minutes.

“The speed and accuracy of the MXCube will satisfy even the most demanding of customers. The streamlined process of setting up jobs quickly and easily is what I find most impressive about the technology,” says DATRON VP of Operations Robert Murphy. " https://bit.ly/2PKGDeu

Here are a few pictures of the MXCube being loaded into our Tech Center. The MX and its Chip Management System fit in pretty nicely alongside the MLCube, M8Cube, and neos. What do you think of the new machine?

Did you know that Great White Sharks have a high speed approach of their own? They quickly swim from below their prey to the surface with the resulting momentum taking the shark out of the water. Keep an eye out for a new "predator" coming soon...

Aluminum, composites, steel and... foam? With geometrically optimized tooling, the same machine that produced your part can also be used to mill its packaging. Video speeds & feeds: 6mm foam cutter @ 30k RPM, 6mm DOC & 3mm foam cutter @ 35k RPM, 4mm DOC. https://bit.ly/3gBEBJy

Should you use an extremely fast feed rate of 300"/min or take things slow at 60"/min? The unpopular answer is "it depends". In the case of shallow roughing of 6061, you should be fine with a full send, but definitely dial it back for finishing passes. https://bit.ly/3eM6HAD

What if you didn't have to stop milling to add tooling? With ToolAssist, operators can repeatedly load up to five tools during machine operation for a greater variety of tools and the ability to use sister tools in series production.

Do you need to produce holes as small as .004" (0.1mm) with smooth walls and well-defined edges? If you're producing parts that require micro drilling, combining high-speed milling techniques with a spray-mist coolant system will help. https://bit.ly/35Mg7Hq

A DATRON Triple Flute Foam End Mill on the DATRON neo made quick work of this foam insert for our sample kits. Keep your eyes open for a special DATRON tooling announcement in the coming weeks.

Speeds / Feeds: 35k RPM, 5k mm/min feed rate, 6mm DOC

Producing the perfect part takes a lot of work. Are you putting the same thought into its packaging? This morning we're CAM'ing out foam inserts in @adskfusion360 for a bottle opener that will be included in the new sample cases for our sales team.
