CNC Programming Handbook - A Comprehensive Guide to by Peter Smid

By Peter Smid

This e-book has earned the name of de facto average for education in addition to reference content material in any respect degrees of desktop numerical regulate programming. hundreds of thousands of academic associations all over the world use the guide because the fundamental textual content for CNC classes. And hundreds of thousands of programmers and computer operators hire it at the store ground. this is often the e-book that actually defines CNC programming. Noteworthy for the author's cautious, uncompromising consciousness to element, this variation comprises reviews and recommendations from enormous quantities of pros within the box. the excellent result's a rare quantity. The booklet is choked with over a thousand illustrations, tables, formulation, counsel, shortcuts and pragmatic examples.

Example text

So far, we have looked at the Z-axis Neglect function and locking of the auxiliary functions. Remember that the Z-axis Neglect function will disable the motion of Z-axis only and the Auxiliary Functions Lock (also known as MST lock) locks miscellaneous functions, spindle functions and tool functions. Another function, also available through the control panel, is called Machine Lock. When this function is enabled, motion of all axes is locked. CONTROL SYSTEM It may seem strange to test a program by locking all tool motions, but there is a good reason to use this feature.

This continuity is important for production, but not practical when proving a new program, for example. To disable continuous program execution, a Single Block switch is provided on the operation panel. In the single block mode, only one program block will be processed each time the Cycle Start key is pressed. On the operation panel, single block mode can be used separately or in combination with other settings that make program proving faster and more accurate. 54 Formula 4: To find the number of characters, if the system memory capacity is known in feet, use the following formula: C = f ´ 120 + where .

Setting for international languages is also possible. Keyboard pads and soft keys are used to input instructions to the control. Existing programs can be modified or deleted, new programs can be added. Using keyboard input, not only the machine axes motion can be controlled, but the spindle speed and feedrate as well. Changing internal parameters and evaluating various diagnostics are more specific means of control, often restricted to service people. Keyboard and screen are used to set program origin and to hook up to external devices, such as a connection with another computer.
