- •By the discipline «Systems of numerical control of machine tools - cnc machine tools» for students of speciality
- •6M072400 «Technological machines and equipment» astana 2016
- •Straight cut nc
- •Numerical Control Kernel
- •Figure 2.4 – Contour rounding example
- •Part Rotating and Indexing
- •X, it is the u axis; y, it is the V axis; z, it is the w axis
- •Figure 4.8 – The programmable milling machine knee would be called a w axis since it moves parallel to the z axis
- •Incremental value (relative value). Coordinates based on the previous entry. Jump-to-jump values. Sometimes called relative coordinates because each entry is based on the last.
- •Figure 5.1 – Turning operation
- •Other lathes and turning machines
- •Drilling and related operations
- •Wireframe and solids
- •Figure 6.1a and 6.1b – Part geometry can be a wireframe, but solids work better -especially when part shape is complex.
- •Figure 7.1 Two basic types of milling operations: (a) peripheral or plain millingand (b) face milling.
- •Milling machines
- •Operating of cnc
- •Cam software system. Dynamic toolpath
- •Feature-Based Machining (fbm)
- •Rest Milling
- •Formatting g-code Blocks
- •It is an error if:
- •Figure 13.6 – The same workpiece with the same prz, but located in each quadrant.
- •Vertical cnc mills, where there are three common holding selections for your plan:
- •Level-Two Programming
- •Figure 14.1 The thread cycle requires a departure point outside both the X and z positions relative to the finished thread.
- •Additional
