      Preface

      Creo Manufacturing is the group of apps in Creo Elements/Pro package that are used to assist in various streams of Computer Aided Manufacturing like NC Assembly, Expert Machinist, CMM, Sheetmetal, Cast Cavity, Mold Cavity, Harness, and Process Plan. This book covers the applications of Expert Machinist, NC Assembly, and CMM apps. Using the Expert Machinist app, you can create NC programs for machining some of the most difficult machining jobs. This app gives you the capability to generate NC programs suitable for 3-axes, 4-axes, or 5-axes milling machines.

      The Creo Manufacturing 9.0 Black Book, is written to help professionals as well as learners in creating NC programs for very complex jobs that are machined in the Machine shop. The book covers almost all the information required by a learner to master the Expert Machinist, NC Assembly, and CMM modules of Creo. It covers basic as well as advanced topics like NC machines, milling tools with their uses, tool setting, machine setting, cutting strategies, NC Features, creation of output for a specific machine, CMM, and so on. Some of the salient features of this book are :

      •Introduction to Manufacturing

      •Types of Machines

      •NC Machines

      •Applications of CAM

      •Starting Creo Parametric Manufacturing

      Introduction to manufacturing

      Manufacturing is the process of creating a useful product by using a machine, a process, or both. For manufacturing a product, there are some steps to be followed:

      •Generating model of final product.

      •Deciding Workpiece; selection of raw material and shape/size of workpiece depends on the application of the product.

      •Forging, Casting, or any other pre machining method for creating layout for final shape.

      •Roughing processes.

      •Finishing Processes.

      •Quality Control.

      These processes are the main area of concern in this book. An introduction of these processes is given next.

      As the Generating Layout of final product is above all the steps, it is the most important step. One should be very clear about the final product because all the other steps are totally dependent on the first step. The layout of final product can be a drawing or a model created by using any modeling software like SolidWorks, Inventor, Solid Edge, and so on. You can also use the Design environment of Mastercam software to create the model.

      The next step is Selection of Raw material/Workpiece. This step is solely dependent on the first step. Our final product defines what should be the raw material and the workpiece shape. Here, workpiece is the piece of raw material of desired shape to be used for the next step or process.

      The next step is Forging, Casting, or any other process for creating outline of the final shape. The outline created for the final shape is also called Blank in industries. In this step, various machines like Press, Cutter, or Moulding machines are used for creating the blank. In some cases of Casting, there is no requirement of machining processes. For example, in case of Investment casting, most of the time there is no requirement of machining process. Machining processes can be divided further into two processes:

      •Roughing Processes

      •Finishing Processes

      These processes are the main discussion area of this book. An introduction to these processes is given next.

      Roughing Process

      Roughing process is the first step of machining process. Generally, roughing process is the removal of large amount of stock material in comparison to finishing process. In a roughing process, the quantity of material removed from the workpiece is more important than the quality of the machining. There are no close tolerances for roughing process, so the main areas of concern are maximum limit of material that can be removed without harming the cutting tool life. So, these processes are relatively cheaper than the finishing process.

      In manufacturing industries, there are three principle machining processes called Turning, Milling, and Drilling. In case of roughing process, there can be turning, milling, drilling, combination of any two, or all the processes. Along with these machining processes, there are various other processes like shaping, planing, broaching, reaming, and so on. But these processes are used in special cases.

      Finishing Process

      Finishing process can include all the machining processes discussed in case of roughing processes but in close tolerances. Also, the quality of machining at required accuracy level is very important for finishing. Along with the above discussed machining processes, there are a few more machining processes like Electric Discharge Machining(EDM), Laser Beam Machining, Electrochemical Machining, and so on. These processes are called unconventional machining processes because of their cutting method. In unconventional machining processes, the cutting is not performed by mechanical pull/push of tool in the workpiece. In these machining processes, electrical discharge, chemical reaction, laser beams, and other sources are used for cutting. Some of the common machines used for machining processes are discussed next.

      Types of Machines

      There are various types of machines for different type of machining process. For example- for turning process, there are machines like conventional lathe and CNC Turner. Similarly for milling process, there are machines called Milling machine, VMC or HMC. Some of the machines are discussed next with details of their functioning.

      Turning Machines

      Turning machine is a category of machines used for turning process. In this machine, the workpiece is held in a chuck (collet in case of small workpieces). This chuck revolves at a defined rotational speed. Note that the workpiece can revolve in either CW(Clockwise) or CCW(Counter-Clockwise) direction but cannot translate in any direction. The cutting tool used for removing material can translate in X and Y directions. The most basic type of turning machine is a lathe. But now a days, lathes are being replaced by CNC Turning machines, which are faster and more accurate than the traditional lathes. The CNC Turning machines are controlled by numeric codes. These codes are interpreted by machine controller attached in the machine and then the controller commands various sections of the machine to do a specific job like asking the motor of cutting tool to rotate in clockwise direction by 10 degree. The basic operations that can be done on turning machines are:

      •Taper turning

      •Spherical generation

      •Facing

      •Grooving

      •Parting (in few cases)

      •Drilling

      •Boring

      •Reaming

      •Threading

      Milling Machines

      Milling machine is a category of machines used for removing material by using a perpendicular tool relative to the workpiece. In this type of machine, workpiece is held on a bed with the help of fixtures. The tool rotates at a defined speed. This tool can move in X, Y, and Z directions. In some machines, the bed can also translate and rotate like in Turret milling machines, 5-axis machines, and so on. Milling machines are of two types; horizontal milling machine and vertical milling machine. In Horizontal milling machine, the tool is aligned with the horizontal axis (X-axis). In Vertical milling machine, the tool is aligned with the vertical axis (Y-axis). The Vertical milling machine is generally used for complex cutting processes like contouring, engraving, embossing, and so on. The Horizontal milling machines are used for cutting slots, grooves, gear teeth, and so on. In some Horizontal milling machines, table can move up-down by motor mechanism or power system. By using the synchronization of table movement with the rotation of rotary fixture, we can also create spiral features. The tools used in both type milling machine have cutting edge on the sides as well as at the tip.

      Drilling Machines

      Drilling machine is a category of machines used for creating holes in the workpiece. In Drilling machine, the tool (drill bit) is fixed in a tool holder and the tool can move up-down. The workpiece is fixed on the bed. The tool goes down, by motor or by hand, penetrating through the workpiece. There are various types of Drilling machine available like drill presses, cordless drills, pistol grip drills, and so on.

      Shaper

      Shaper is a category of machines, which is used to cut material in a linear motion. Shaper has a single point
