Illinois Manufacturer Uses CAD-CAM Technology To

Increase Quality,Production &

Profitability

KPI Machiningl KPI Machining, Sheridan Illinois in order to stay productive and

profitable in their CNC machining while providing quality parts, took to CAD/CAM technology to give them an edge.

l KPI Machining is a job shop that produces CNC milled and CNC turned components with an importance on producing low quantity orders (1-500 parts).

l When KPI turned to technology to help them succeed they found BobCAD-CAM for CNC programming software. KPI now uses the BobCAD-CAM Mill Pro and Lathe CAD/CAM to design and produce parts ,fixtures and their tooling.

l KPI Machining reported that they rely on BobCAD-CAM for accurate 3D milling for solid modeling and programming of complex geometry for their CNC lathe. Obtaining a cycle time from a machining simulation allows them to more accurately quote parts. they also use BobCAD-CAM to produce technical sketches for customer verification and procurement of outsourced services.

Supermilll The CAM software gave them all of the high speed elements they

needed without having to spend much. Cutting tools included a 1/2-inch XPVS500-030 carbide end mill from Supermill.

l The part was machined at 2250 RPM, 56 IPM on the initial test run with an 8% climb step-over, 8% conventional step-over and 1 inch engagement. The Initial run came in at 3.3 lbs removed in 6.8 minutes and the same roughing tool was used to machine over 55 parts!

l The same tool was being used for roughing the next operation. But KPI preferred to use the 1/2-Inch cutting tool since this component required that size or less for finishing as well as that the tool cost $65 and it can be sharpened again by the manufacturer, then the BobCAD toolpath can quickly be re-programmed to use the re-sharpened cutter.

l They prefer not to implement a variety of different type roughing tools on such a low quantity run as this is equivalent to less money in the job, less setup/programming and operator intervention.

l KPI reported that the Adaptive Roughing function is surprisingly easy to program and takes no longer than a drilling operation to setup. No chirping in corners equals maximum tool life for carbide, and no unforeseen gouges in the part from tool deflection in corners.
