Digitization for Highly Accurate 3D Laser Processing of Customer‐specific Tools

Abstract

Cutting tool manufacturing by laser technology has developed quickly during the past fifteen years. Compared to conventional machining methods such as grinding or eroding, laser processing does not require any additional elements such as coolant, grinding wheels, erosion wire, discs, etc. If ultrashort laser pulses are used together with optimized laser parameters, heat input into the material can be negligible. Additionally, there are no processing forces or tool wear present during laser manufacturing. For these many reasons, autonomous production of metallic or diamond tools is feasible and highly interesting.

Advancements in material removal mechanism and surface integrity of high speed metal cutting: A review

“…Integral PCD tools were also developed as seen in Fig. 27c-e to realize HSMC of different workpiece materials such as graphite and alloys [229]. The PCD tools were made by either ultrafast laser machining (Fig.…”

“…The PCD tools were made by either ultrafast laser machining (Fig. 27c,d) [229] or additive manufacturing (Fig. 27e) [230].…”

“…High speed cutting toolsUnder the demand of eco-friendly manufacturing, the development of new advanced cutting tool materials and structures as well as tool coatings that can achieve high cutting speeds without coolant is being pursued by both academia and industries. Ultrafast laser machining[229] and additive manufacturing [230] provide new solutions for fabricating ultra-hard cutting tools with dense tooth structures that can effectively improve the cutting speed. Integral ultra-hard cutting tools such as solid ceramic cutting tools or PCD tools adaptable for HSMC has attracted more attention and would be a research hotspot in the near future.…”

“…The automation cell is configured into a defined layout of blank storage pallets, providing different blank diameters and finish tool pallets for finished products. In a first autonomous production study [4], such configured machines are connected to a customer EWAG Ewag AG is a member of the UNITED GRINDING Group which employs approximately 2,500 people. Together with our sister company, Walter Maschinenbau GmbH, we consider ourselves to be a supplier of systems and solutions for the complete machining of tools and can offer a wide range of products, including grinding, eroding, laser machining, measurement and software.…”
