OK Page 44 Completes the circle and exits the command. Mastercam Interface NEW! If creating several arcs with the same diameter, click on the locker icon to lock the diameter. Press the Enter key. A Cyan colored circle is displayed, indicating the circle is a "live" entity. Altering parameters on the ribbon bar can still change live entities.
Fillet A Fillet is an arc between two entities. Creating a Relief using Fillet command Follow the steps below to create a Relief fillet between two lines. Select the chamfer Method and fill in any open fields. Function prompts will pop up in the graphic area to help you select entities to create the chamfer. To set the point style, right mouse click in the graphics window to open the Mini Toolbar.
Click on the arrow to the right side of the Point Style in the Mini Toolbar and select the desired style as shown. The Point Dynamic command which creates a point along an entity by dragging the cursor along the entity and clicking.
Item Definition Distance along Specifies the position of the point on the selected entity. Enter a value in the Along field, and select an entity on which to place the point.
Point Position Panel Point Position panel below allows editing of the point coordinates while the point is live. Point allows you to create a point from existing geometry or by entering X, Y, Z coordinates. Thread Point allows you to create a thread point that specifies where a wire machine threads the wire. Cut Point allows you to create a cut point that specifies where a wire machine cuts the wire. Allow editing of the point coordinates while the entity is still live.
This places a point at the coordinates: X1, Y1. More Point Function You should be able to create points using any of these options by simply following the function prompts. If you have problems, use Mastercam help Alt-H. The Break at Points command allows you to break lines, arcs and splines at points that lies on them. You have to have the points already created along the entities and to include them in the selection.
Use window selection to include the points. The rest of the options are define as shown. For example, the Rectangular shapes command creates rectangles, obrounds, and D-holes. You could create these objects using line and arc commands. However, the rectangle shapes command makes creating these shapes easier by defining them with settings and parameters.
Shapes Group Commands The following commands are organized in the Shapes group. Rectangle Panel The Rectangle option uses the panel shown below. The following options are available in the Create Letters dialog box.
The command creates a rectangular or a cylindrical shape. This function is especially useful to determine the overall dimensions of a part. Since Mastercam , you can create center points on each face of the box. The Bounding Box Basic tab should look as shown. Drafting Mastercam has extensive drafting capabilities. Unless you are doing tool design, you probably do not need to create detailed drawings. However, some basic dimensioning skills are useful for creating setup sheets, documenting your work for future reference, or communicating your ideas to others.
To learn more about drafting functions, select Alt-H for Mastercam Help. In the Basic tab, you can choose the method in which you create the dimension between Auto, Horizontal and Vertical. You can add the display for the arc symbols and modify the appearance of the witness lines.

Allows you to select one of the available planes used to draw and machine a lathe part. Find a plane Allows you to find an existing plane previously defined. Display options Allows you to customize which planes are shown, and if the gnomon and plane info are displayed.
This chuck revolves at a defined rotational speed. 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:. 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 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 is a category of machines, which is used to cut material in a linear motion. Shaper has a single point cutting tool, which goes back-forth to create linear cut in the workpiece. This type of machine is used to create flat surface of the workpiece. You can create dovetail slot, splines, key slot, and so on by using this machine. In some operation, this machine can be an alternative for EDM. Planer is a category of machines similar to Shaper.
The only difference is that, in case of Planer machine, the workpiece reciprocates and the tool is fixed. There are various other special purpose machines SPMs , which are used for some uncommon requirements. The machines discussed above are conventional machines. The unconventional machines are discussed next. Electric Discharge Machine is a category of machines used for creating desired shapes on the workpiece with the help of electric discharges.
In this type of machines, the tool and the workpiece act as electrodes and a dielectric fluid is passed between them. The workpiece is fixed in the bed and tool can move in X, Y, and Z direction. During the machining process, the tool is brought near to the workpiece.
Due to this, a spark is generated between them. This spark causes the material on the workpiece to melt and get separated from the workpiece. This separated material is drained with the help of dielectric fluid. There are two types of EDMs which are listed next. In this type of EDM, a brass wire is commonly used to cut the material from the workpiece.
This wire is held in upper and lower diamond shaped guides. It is constantly fed from a bundle. In this machine, the material is removed by generating sparks between tool and workpiece. A Wire-cut EDM can be used to cut a plate having thickness up to mm. In this type of EDM, a metal electrode is used to cut the material from the workpiece.
The tool and the workpiece are submerged in the dielectric fluid. Power supply is connected to both the tool and the workpiece. When tool is brought near the workpiece, sparks are generated randomly on their surfaces. Such sparks gradually create impression of tool on the workpiece. Electro Chemical Machine is a category of machines used for creating desired shape by using the chemical electrolyte.
This machining works on the principles of chemical reactions. Laser Beam Machine is a category of machines that uses a beam, a highly coherent light. This type of light is called laser. A laser can output a power of up to MW in an area of 1 square mm. A laser beam machine can be used to create accurate holes or shapes on a material like silicon, graphite, diamond, and so on. The machines discussed till now are the major machines used in industries.
Some of these machines can be controlled by numeric codes and are called NC machines. NC Machines and their working are discussed next. An NC Machine is a manufacturing tool that removes material by following a predefined command set. An NC Machine can be a milling machine or it can be a turning center.
NC stands for Numerical Control so, these machines are controlled by numeric codes. These codes are dependent on the controller installed in the machines. There are various controllers available in the market like Fanuc controller, Siemens controller, Heidenhain controller, and so on. The numeric codes change according to the controller used in the machine.
These numeric codes are compiled in the form of a program, which is fed in the machine controller via a storage media. The numeric codes are generally in the form of G-codes and M-codes.
For understanding purpose, some of the G-codes and M-codes are discussed next with their functions for a Fanuc controller. These codes as well as the other codes will be discussed in the subsequent chapters according to their applications. As there is a long list of codes which are required in NC programs to make machine cut workpiece in the desired size and shape, it becomes a tedious job to create programs manually for each operation.
Moreover, it take much time to create a program for small operations on a milling machine. Various applications of CAM are discussed next. Computer Aided Manufacturing CAM is a technology which can be used to enhance the manufacturing process. In this technology, the machines are controlled by a workstation. This workstation can serve more than one machines at a time.
Using CAM, you can create and manage the programs being fed in the workstation. Some of the applications of CAM are discussed next. CAM can be used to manage more than one machines at the same time with less human power. There are various software companies that provide the CAM software solutions. CNC Software is one of those companies which publishes Mastercam software. Mastercam is one of the most popular software for CAM programming. The link for downloading the software will be sent to the e-mail ID specified in the form; refer to Figure A file of approximately 1.
Follow the instructions to install as displayed. The Mastercam Design application window will be displayed; refer to Figure By default, CAD environment is active. Whether you use the stand-alone program of Mastercam or the integrated one with SolidWorks, the approach for creating NC programs is same.
