In most cases, the answer is no<\/strong>.<\/p>\n\n\n\n Unlike metals, ceramics cannot reliably maintain sharp corners. Instead, corners should be designed with chamfers (C)<\/strong> or fillets (R)<\/strong>. Understanding why this is necessary\u2014and how to choose between C and R\u2014is critical for successful ceramic part design and manufacturing.<\/p>\n\n\n\n Ceramic materials are characterized by high hardness and high brittleness<\/strong>. While these properties make ceramics excellent for wear resistance, thermal stability, and electrical insulation, they also introduce a key limitation:<\/p>\n\n\n\n Sharp corners create stress concentration.<\/strong><\/p>\n\n\n\n At a 90-degree corner, mechanical stress, thermal stress, and residual machining stress tend to accumulate. In ceramics, this often leads to:<\/p>\n\n\n\n In addition, ceramic cutting tools cannot achieve the same sharpness as metal tools. Tool geometry, tool radius, and brittleness of the material all make true sharp corners impractical.<\/p>\n\n\n\n For these reasons, sharp internal or external corners should be avoided at the design stage<\/strong>.<\/p>\n\n\n\n Chamfer (C) is a straight, angled cut applied to a corner.<\/strong><\/p>\n\n\n\n Chamfers are simple, economical, and widely used\u2014especially on external edges.<\/p>\n\n\n\n Fillet (R) (or radius) is a rounded corner formed by a circular arc.<\/strong><\/p>\n\n\n\n Fillets are highly effective at reducing stress concentration and are essential in internal corners.<\/p>\n\n\n\n External corners are chamfered (C-corners), while internal corners are rounded (R-corners).<\/p>\n\n\n\n For external edges, chamfering is easier, more efficient, and less costly to machine.<\/p>\n\n\n\n However, for internal corners, rounded corners are essential, and C-corners are practically impossible to produce on internal corners (due to tool interference).<\/p>\n\n\n\n Choosing between C and R is not just a drawing detail\u2014it directly affects whether a ceramic part can be machined reliably.<\/p>\n\n\n\n In summary:<\/p>\n\n\n\n If you are unsure which edge treatment method is suitable for your ceramic parts, we recommend consulting us in the early design stages.
