Prerequisites
FORMA ( P )
Knowledge of machining and unconventional production methods.
Course Enrolment Limitations
The course is offered to students of any study field.
Course objectives supported by learning outcomes
The aim of the course is to acquaint students with modern practices NC programming using CAD / CAM system. The courses will gain basic knowledge of programming NC milling machines, lathes, wire cutters and lasers. Seminar work is awarded in cooperation with the Training center. At the end of the course students should be able to:program CNC machines.
Learning outcomes
Student is able to:
- describe the development of CAD/CAM systems
- evaluate the benefits of CAD/CAM systems with the usability for NC machine programming
- describe the individual operations used in the HSC and HSM programming
- fully develop the program for production of specified components by means and operations in HSC and HSM
Syllabus
  • 1. Introduction to the development of CAD-CAM systems: machines controlled by cams, the first numerically controlled machines - management using paper tape; laborious effort to facilitate the programming of numerically controlled machines - the first CAD / CAM systems, linking design with technology - the use of data for programming NC machines; 2D drawing and the use of 2D data, drawing in 3D - 3D data processing; evaluate the advantages of CAD / CAM systems for NC programming and direct programming of NC machine; economic evaluation of the support program from the perspective of several years of development, overview of application areas machining - turning milling, wire EDM - shaft, wire cutting, laser cutting, plasma cutting, flame, water jet cutting, welding – 2 axis, multi-axis cutting.
  • 2. Milling 2D, 2.5D Milling: machine cycles; advantages of 2D programming - using radius compensation, the use of 3D models - feature recognition model for acceleration and production programming.
  • 3. 3D milling - roughing strategy: roughing, rest roughing, strategies for HSC and HSM - adoptive roughing.
  • 4. 3D milling - a strategy for finishing: Finishing strategies for steep and flat areas, combined machining, machining residual.
  • 5. Multi-axis indexed milling, five-axis milling smoothly.
  • 6. Turning - rotating parts machining, machining with driven tools, multi-axis machines.
  • 7. Repetition: machining.
  • 8. Wire: the notion of programmatic and auxiliary plane; 2-axis machining, with constant and variable askance; production of cutting tools - planes position, production dies, punch, unattended cutting.
  • 9. Wire: four axis cutting, synchronization connections for four-axis cutting, production of cutting tools with variable shear plane in the Z plane, production lathe tools, waste-free cut.
  • 10. Trenching, excavating track, production of electrodes.
  • 11. Laser cutting, water jet cutting, plasma: manual deployment work-pieces in sheet metal, auto machining; treatment pathways and technologies; semiautomatic and automatic deployment of the work-piece on the board plate.
  • 12. Multi-axis laser cutting, water jet.
  • 13. Repetition: unconventional machining methods.
