Accepted: 7 November 2017The paper presents an attempt to analyze comparative machinability of two different varieties of nitinol alloy type, or compare the susceptibility of these materials to change the volume, shape and dimension of adopted machining conditions. The machinability of the material can not be fully determined numerically by only one independent factor. Therefore multivariate analysis technique of weighted diagram radar was developed by authors. This technique allowed for the comprehensive identification machinability analyzed varieties of nitinol alloy exclusively on the basis of the specified in literature directional material properties and general recommendations tool manufacturers on the cutting conditions. In the paper the full usefulness of this technique to demonstrate the differences in machinability of different varieties of the same species alloy, without the need for lengthy and cost-intensive experimental trials was presented.

The selected indicators of machinability of NiTi based shape memory alloys has been examined. The paper presents research of possibilities of shape memory alloy like low-temperature (austenitic) Ni53Ti47 (Nitinol) with a coated cemented carbide tool, cutting force components (F f -the feed force, F p -the passive force, F c -the main cutting force). In the work, a special attention was paid on the main cutting force components at variable cutting speed (v c ).

The nickel‐titanium (NiTi) alloy, “Nitinol”, has become a prominent name in the medical device industry amongst medical device manufacturers. The unique properties of the material, such as the shape memory effect and pseudoelasticity, have earned the material increasing popularity for new product innovations. Amongst the various manufacturing processes for metal alloys, laser micromachining has taken the lead for processing Nitinol‐based products. This literature review provides an analysis of the history and applications of Nitinol, an overview of the microstructure of the material, and a review of the current manufacturing methods for laser cutting medical‐grade Nitinol. A more in‐depth focus is placed on the realm of laser processing and the challenges associated with the manufacturing process. Ultrafast femtosecond pulse processing delivers promising results and quality for manufacturing Nitinol medical devices. However, there exists a need to investigate potential approaches to increase the cutting speed of the process to enhance throughput and stay competitive in a growing market due to the cutting speed being over 4‐times slower than long pulse cutting. Many tactics to address the problem are discussed, ranging from laser selection, processing parameters, and non‐traditional laser processing approaches.This article is protected by copyright.
