Continuous fiber-reinforced thermoplastics (FRTP) are gaining increasing interest as a lightweight material. However, production processes such as thermoforming rely on costly molds, making them unsuitable for individual parts or small series production. Therefore, realizing an incremental sheet forming (ISF) process for FRTP is very desirable. As direct application of ISF to FRTP is impossible, researchers placed the FRTP between two metal sheets, allowing it to slide between them during single point incremental forming (SPIF). So far, only traditional tool path strategies for metal SPIF, such as the z-level or the spiral approach, have been used, which do not consider the draping requirements of woven reinforcement fibers. To optimize the forming process and prevent the development of wrinkles or other defects in the organo sheet, we propose and test novel tool path strategies for the SPIF of an FRTP sandwiched between two metal sheets. Results show that the proposed strategies have a positive impact on part quality, as fiber orientation-based tool path approaches show less wrinkling and higher part accuracy in SPIF without support.
