CNC Programming Skills: Program Entry and Editing on Fanuc Machines


Book Description

Do you know how to insert a part of a program into another program at the desired location? Background editing?? Using PCMCIA card??? Or, maybe, a simple task such as replacing G02 by G03 in the whole file???? When it comes to manual program entry on the machine, or searching / deleting / editing / copying / moving / inserting an existing program residing in the control memory or the PCMCIA card, most people resort to trial and error method. While they might be able to accomplish what they desire, the right approach would save a lot of their precious time. If this is exactly what you want, this book is for you. The information contained herein is concise, yet complete and exhaustive. The best part is that you can enjoy the convenience of having the wealth of useful information on editing techniques even on your smart phone which is always with you! You would often need to refer to it because it is not possible to memorize all the steps which are many a time too complex and devoid of common logic, so as to make the correct guess. The following excerpt from the book would give an idea of the methodical and step-by-step approach adopted in the book: Writing a file on the memory card: The following operation will save program number 1234 in the memory card, with the name TESTPRO: * Select the EDIT mode on the MOP panel. * Press the PROG key on the MDI panel. * Press the next menu soft key. * Press the soft key CARD. * Press the soft key OPRT. * Press the soft key PUNCH. * Type 1234 and press the soft key O SET. * Type TESTPROG and press the soft key F NAME. * Press the soft key EXEC. While the file is being copied on the memory card, the character string OUTPUT blinks at the lower right corner of the screen. Copying may take several seconds, depending on the size of the file being copied. If a file with file name TESTPROG already exists in the memory card, it may be overwritten unconditionally or a message confirming the overwriting may be displayed, depending on a parameter setting. In case of such a warning message, press the EXEC soft key to overwrite, and CAN soft key to cancel writing. However, system information such as PMC ladder is always overwritten unconditionally. The copied file is automatically assigned the highest existing file number plus one. The comment, if any, with the O-word (i.e., in the first block of the program) will be displayed in the COMMENT column of the card directory. To write all programs, type -9999 as the program number. In this case, if file name is not specified, all the programs are saved in file name PROGRAM.ALL on the memory card. A file name can have up to 8 characters, and an extension up to 3 characters (XXXXXXXX.XXX). Repeat the last three steps to copy more files. Finally, press the CAN soft key, to cancel the copying mode and go to the previous menu.

Getting Started with CNC


Book Description

Getting Started with CNC is the definitive introduction to working with affordable desktop and benchtop CNCs, written by the creator of the popular open hardware CNC, the Shapeoko. Accessible 3D printing introduced the masses to computer-controlled additive fabrication. But the flip side of that is subtractive fabrication: instead of adding material to create a shape like a 3D printer does, a CNC starts with a solid piece of material and takes away from it. Although inexpensive 3D printers can make great things with plastic, a CNC can carve highly durable pieces out of a block of aluminum, wood, and other materials. This book covers the fundamentals of designing for--and working with--affordable ($500-$3000) CNCs.




Theory and Design of CNC Systems


Book Description

Computer Numerical Control (CNC) controllers are high value-added products counting for over 30% of the price of machine tools. The development of CNC technology depends on the integration of technologies from many different industries, and requires strategic long-term support. “Theory and Design of CNC Systems” covers the elements of control, the design of control systems, and modern open-architecture control systems. Topics covered include Numerical Control Kernel (NCK) design of CNC, Programmable Logic Control (PLC), and the Man-Machine Interface (MMI), as well as the major modules for the development of conversational programming methods. The concepts and primary elements of STEP-NC are also introduced. A collaboration of several authors with considerable experience in CNC development, education, and research, this highly focused textbook on the principles and development technologies of CNC controllers can also be used as a guide for those working on CNC development in industry.

Basics of CNC Programming


Book Description

Before the introduction of automatic machines and automation, industrial manufacturing of machines and their parts for the key industries were made though manually operated machines. Due to this, manufacturers could not make complex profiles or shapes with high accuracy. As a result, the production rate tended to be slow, production costs were very high, rejection rates were high and manufacturers often could not complete tasks on time.Industry was boosted by the introduction of the semi-automatic manufacturing machine, known as the NC machine, which was introduced in the 1950’s at the Massachusetts Institute of Technology in the USA. After these NC machine started to be used, typical profiles and complex shapes could get produced more readily, which in turn lead to an improved production rate with higher accuracy.Thereafter, in the 1970’s, an even larger revolutionary change was introduced to manufacturing, namely the use of the CNC machine (Computer Numerical Control). Since then, CNC has become the dominant production method in most manufacturing industries, including automotive, aviation, defence, oil and gas, medical, electronics industry, and the optical industry. Basics of CNC Programming describes how to design CNC programs, and what cutting parameters are required to make a good manufacturing program. The authors explain about cutting parameters in CNC machines, such as cutting feed, depth of cut, rpm, cutting speed etc., and they also explain the G codes and M codes which are common to CNC. The skill-set of CNC program writing is covered, as well as how to cut material during different operations like straight turning, step turning, taper turning, drilling, chamfering, radius profile, profile turning etc. In so doing, the authors cover the level of CNC programming from basic to industrial format. Drawings and CNC programs to practice on are also included for the reader.




Advanced Design and Manufacturing Based on STEP


Book Description

Design and manufacturing is the essential element in any product development lifecycle. Industry vendors and users have been seeking a common language to be used for the entire product development lifecycle that can describe design, manufacturing and other data pertaining to the product. Many solutions were proposed, the most successful being the Stadndard for Exchange of Product model (STEP). STEP provides a mechanism that is capable of describing product data, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing, sharing and archiving product databases. ISO 10303-AP203 is the first and perhaps the most successful AP developed to exchange design data between different CAD systems. Going from geometric data (as in AP203) to features (as in AP224) represents an important step towards having the right type of data in a STEP-based CAD/CAM system. Of particular significance is the publication of STEP-NC, as an extension of STEP to NC, utilising feature-based concepts for CNC machining purposes. The aim of this book is to provide a snapshot of the recent research outcomes and implementation cases in the field of design and manufacturing where STEP is used as the primary data representation protocol. The 20 chapters are contributed by authors from most of the top research teams in the world. These research teams are based in national research institutes, industries as well as universities.
