CAD/CAM systems include Cimatron, Toolchest, Cadkey, XMD
, and Power Mill.
Calendering or extruding compounds reinforced with engineered elastomer leads to modular anisotropy--a difference in modulus between the machine direction (MD) and cross machine direction (XMD
Of course, they require that the audio or the video be available in RA, XMD
, or DCR format, respectively.
Cornerstone Technology's Expert Mold Designer (XMD
) software, which is a separate add-on for KeyCreator part-design software from Kubotek, has a brand-new Mold Feasibility module that evaluates a part's moldability by examining drafts, undercuts, wall thicknesses, etc.
MD modulus is about 5x that of XMD
modulus in 2 mm test pieces of this NR/SBR fire tread compound.
Once parting lines have been modeled in Cadkey, which serves as XMD
's CAD package (other systems can also be used), XMD
generates a complete 3-D mold assembly and draws it in four or more 2-D views.
