FEA For The Shop Floor
once so a final shape matches the design without rework. The material and drilling model worked well for two of the test feed rates. The values are average height because real world operations generate scatter about the calculated heights. At lower rotational speeds, the burr forms more by the tool...

Tips for no-melt machining
of cracking. For general sawing operations, good blade design can reduce the frictional heat between tool and part. For example, the angle formed between the tooth face and a line passing through the blade's rotational axis or rake angle should be 0° for rip and combination blades. The teeth should...

Solid structures for machining centers
at the center of the mill need not be considered because it can be compensated for and does not affect the machined surface profile. The slope of the mill is a function of the distance from the cutting plane to the center of the Y-axis slide, rotational stiffness, and displacement of the mill center...
