- What are the key considerations and best practices in programming multi-axis CNC machines to achieve complex machining tasks, and how does advanced CAM (Computer-Aided Manufacturing) software play a role in streamlining the process?arrow_forwardE Expert Q&A 1. Shaper (#X) Machine function and design requirements: The main function of this machine is to make surface more smooth; The required movements are: Reciprocating movement of planer knife and feed movement of the bow. It is required that the cutting speed is uniform, while the quirkily return is included. The basic data is: principal axis rotation speed is 60 r/min, the max length is less than 450 mm, the distance between working surface and the floor is 800 mm. Travel speed ratio co-efficient is 1.5, allowable pressure angle 15°, cutting quantity is 0.1~0.5 mm. Requirements: 1. Freedom calculations; 2. Force analysis; 3. Make this machine, and display; please give a solution with given condition.arrow_forwardSummarise and discuss the working principles, functional elements, and control of Computer Numerical Control (CNC) machines. It is required to discuss the similarities and differences about the working principles between CNC machining and Additive Manufacturing & 3D Printing (AM-3DP) systems such as Fused Deposition Modelling (FDM), Binder-Jetting (BJ), Stereolithography (SLA), Selective Laser Sintering (SLS).arrow_forward
