Stepped Pulley Mill. Much of the information presented in this document is from my own personal experiences, and all of the images that are located throughout the document were taken by me using a Nikon Coolpix 4300 and a Nikon D70s. For those images where I have included drawings, they were created using either TurboCADCAM or SolidWorks.

When making inquiries or ordering parts, all pertinent information must be stated on both the inquiry and order. This information should include all of the following components. 1. Casting shape – either by drawing or pattern. Drawings should include dimensional tolerances, indications of surfaces to be machined, and datum points for locating.
part size. The important point to take away fr om this figure is the general trend showing typical achievable part tolerances grow as a function of parts size. In other words, the ability to achieve a certain tolerance is a function of part size. As an example, let's use a pair of the 6″ measuring calipers found in lab. Do these

Machining Operations and Part Geometry Each machining operation produces a characteristic part geometry due to two factors: 1. Relative motions between the tool and the workpart •Generating –part geometry is determined by the feed trajectory of the cutting tool 2. Shape of the cutting tool •Forming –part geometry is created by the
HAAS Mill. The information in this workbook may apply in whole or in part to the operation of other CNC machines. Its use is intended only as an aid in the operation of the HAAS Milling Machine. For a complete explanation and an in-depth descrip-tion, refer to the Programming and Operation Manual that is supplied with your HAAS Lathe.
designs for three components: a milling machine part, a lathe part, and a sheetmetal part. For each component, a poor design drawing is presented, followed by an improved design drawing, followed by a detailed explanation of why the changes facilitate DFM.
The part program is a sequence of instructions, which describe the work, which has to be done on a part, in the form required by a computer under the control of a numerical control computer program. It is the task of preparing a program sheet from a drawing sheet. All data is fed into the numerical control system using a standardized format.

4.1.1 Part Drawing Component or part drawing is a detailed drawing of a component to facilitate its manufacture. All the principles of orthographic projection and the technique of graphic representation must be followed to communicate the details in a part drawing.

The contact plate on the drawing is to be produced on a CNC vertical milling machine from a blank of AlMg1 dimensioned 100 x 100 x 25 mm. Prepare, test and correct the manufacturing process with the MasterCAM CNC Milling Simulator. Define the workpart zero, work out the process layout, set-up form and NC program.
One of the biggest differences between making a few or many parts is in the design of work-holding fixtures. Prototype machining emphasizes quick, simple and cheap work holding such as vises, clamps, solutions screws or even glue or -doublesided tape.High production parts allow the cost of fixtures to be amortized

The CAD/CAM process integrates the geometry, toolpath and the G-code program to create a part on a milling machine. Three different steps are taken for a CAD/CAM process. First the geometry for the part is created as a CAD file. The second step is to create a toolpath by assigning a cutting option to a section of the drawing.
