Controlling without destroying: a vital challenge in high-security industries<\/strong><\/h2>\n

In sectors such as aeronautics, nuclear power, space, and medicine, it is essential to verify the integrity of mechanical parts <\/strong>without altering them. This is the purpose of non-destructive testing (NDT)<\/strong> techniques, which identify cracks, porosity, inclusions, or delamination in a part without having to cut it or subject it to destructive testing.<\/p>\n

However, to ensure the effectiveness of these tests, the measuring tools (ultrasound, X-rays, eddy currents, thermography, etc.) must be perfectly calibrated<\/strong>. This requires the use of reference parts<\/strong> with known defects that are perfectly dimensioned, positioned, and reproducible. These artificial defects (or simulated indications<\/strong>) are used as standards to validate the sensitivity of equipment, train operators, or qualify an NDT method.<\/p>\n

The challenge is considerable: artificial defects (cracks, micro-cavities, fissures, delaminated areas) must be created in a perfectly compliant part<\/strong>, without altering its overall structure, without introducing parasitic mechanical stresses, and with extreme geometric precision<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”8878″ img_size=”large” alignment=”center” css=””][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n

Electrical discharge machining and micro-machining: the only techniques capable of creating controlled defects<\/strong><\/h2>\n

Only a technology such as electroerosion<\/strong> (EDM<\/strong>), combined with advanced micromechanics<\/strong>, can simulate internal or external defects<\/strong> with micron precision. Thanks to its non-contact process, electroerosion can remove material locally without generating stress, excessive heat, or unintended microcracks. Simulated cavities<\/strong> can thus be created in the hardest materials (titanium, Inconel, hardened steel, carbide, etc.) with controlled geometry.<\/p>\n

Defects can take the form of calibrated cracks<\/strong>, radial or axial microcracks<\/strong>, fine slits<\/strong>, elliptical cavities<\/strong>, or even defects that are not visible<\/strong> on the surface, intended for ultrasound or tomography testing. Their depth, orientation, and surface area are defined with precision, often based on plans provided by customers or qualification laboratories.<\/p>\n

Micro-drilling<\/strong> can also be used to create blind or through holes<\/strong>, which are used as standards in leak or visualization tests. All of this is accompanied by dimensional measurements<\/strong> carried out in an air-conditioned metrology room, using optical tools and probes, ensuring the traceability of defects.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”8886″ img_size=”large” alignment=”center” css=””][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n

Mecasoft: generator of artificial defects on reference parts for non-destructive testing<\/strong><\/h2>\n

For many years, Mecasoft has been working with laboratories specializing in non-destructive testing<\/strong>, certification bodies<\/strong>, and leading manufacturers <\/strong>to produce test parts with controlled artificial defects<\/strong>. These parts are used in calibration benches, equipment approval procedures, and training for qualified personnel.<\/p>\n

Mecasoft uses ultra-fine electroerosion processes<\/strong> to create internal defects with variable geometry in highly technical materials. Each part is inspected and delivered with a complete measurement report<\/strong>, allowing the shape, depth, and exact location of the defects to be validated.<\/p>\n

The company also offers its expertise in precision micromechanics<\/strong>, its specialized machines park<\/strong>, and its experienced team<\/strong> to co-develop specific parts in partnership with its customers. Thanks to its commitment to quality and its ability to work on a per-unit or small-batch basis<\/strong>, Mecasoft has become a recognized player in this niche field.[\/vc_column_text][\/vc_column][\/vc_row][vc_row link=”url:https%3A%2F%2Fwww.mecasoft.be%2Fcontact%2F|title:Contact” smooth_scroll=”n” size=”big” btn_width=”btn_auto_width” custom_btn_width=”200″ button_alignment=”btn_center” animation=”” font_size=”14px” button_padding=”12px 18px 12px 18px” border_width=”0px” border_radius=”1px” btn_decoration=”none” text_color=”” default_btn_border=”y” default_btn_border_color=”” default_btn_bg=”y” default_btn_bg_color=”” default_btn_hover=”y” text_hover_color=”” default_btn_border_hover=”y” default_btn_border_hover_color=”” default_btn_bg_hover=”y” bg_hover_color=”” link_font_size=”14px” link_font_style=”:bold:” link_icon_size=”12px” link_padding=”4px 0px 4px 0px” link_text_color=”” link_hover=”n” link_text_hover_color=”” link_decoration=”upwards” link_border_width=”2px” link_border_color=”” icon_picker=”” icon_gap=”8px” icon_align=”left” css=”.vc_custom_1765289587775{margin-top: 40px !important;margin-bottom: 40px !important;}” general_settings=”” normal_settings=”” hover_settings=”” link_general_settings=”” link_normal_settings=”” link_hover_settings=”” link_underline_settings=””][vc_column]
