What is a Swiss lathe machine used for?
Swiss-style lathes are used for machining components requiring extreme accuracy. some of these lathes are capable of machining to within 0.00025mm or 0.00001in. Swiss-style lathes are used for smaller and/or longer workpieces, the lathes are applicable for different industries to machine parts.
What is the reason of the frequency limitation in bridge?
A bridge has an upper frequency limit because above that frequency the measuement accuracy fails because of stray capacitance and inductance inside the bridge device.
Why this cnc machines are used?
the cnc technology is applicable for high accuracy machining and high speed machining,it si more efficient than the conventional methods like lathe,driller,etc..by the application of cnc the production time can be reduced and there by increase the productivity and profit .
What are the difference between conventional milling machine and CNC milling machine?
Non conventional Machining is a recent development in machining techniques. It is based on unconventional machining techniques using Laser beam, Electron beam, Electric arc etc. Conventional machining involves the direct contact of tool and work -piece, whereas unconventional machining does not require the direct contact of tool and wor piece. Conventional machining has many disadvantages like tool wear which are not present in Non-conventional machining. Examples : Electric arc machining, Laser cutting , electro discharge machining, plasma cutting etc Advantages of Non-conventional machining: 1) High accuracy and surface finish 2) no direct contact of tool and workpiece, so there is less/no wear 3) tool life is more 4 ) quieter operation Disadvantages of non-conventional machining: 1) high cost 2) complex set-up 3) skilled operator required
Which meter has the highest accuracy in the prescribed limits of frequency RANGE?
A digital frequency meter typically has the highest accuracy within its prescribed limits of frequency range compared to analog frequency meters. Digital frequency meters offer precise frequency measurements with less likelihood of error due to their advanced technology and digital display.
Why is clear and dimensional accuracy needed in marking out to specification and drawing requirements?

What are vee blocks and clamps used for?
Vee blocks are used to securely hold round or cylindrical workpieces in place during machining or inspection operations. Clamps are used to secure workpieces to a work surface or fixture to prevent movement during machining, welding, or other fabrication processes. Both tools are essential for ensuring precision and accuracy in manufacturing and machining processes.
What is tolerance in laser beam machining?
Tolerance in laser beam machining refers to the allowable deviation from the desired dimensions in the final workpiece. It is the acceptable range within which the dimensions of the machined part can vary without compromising its functionality or quality. Tight tolerance requirements in laser beam machining indicate the need for high precision and accuracy in achieving the desired part dimensions.
What can you measure with micrometer?
A micrometer can measure the thickness, diameter, or depth of small objects with high precision. It is commonly used in engineering, machining, and manufacturing to ensure accuracy in measurements.
What is Unconventional machining technique?
In ordinary machining we use harder tool to work on workpiece , this limitation is overcome by unconventional machining. unconventional machining is directly using some sort of indirect energy for machining. Example : sparks, lasers, heat , chemicals etc.. applied in EDM ,laser cutting machines...etc

what is cnc machining in 3d printing?
CNC machining, or Computer Numerical Control machining, is a subtractive manufacturing process frequently employed in conjunction with 3D printing to achieve precision and refinement in the production of complex parts. While 3D printing is renowned for its additive layer-by-layer approach, CNC machining involves the removal of material from a solid block to achieve the desired shape and specifications. In the context of 3D printing, CNC machining is often used for post-processing or finishing steps. This hybrid approach leverages the benefits of both technologies: the rapid prototyping capabilities of 3D printing and the high-precision finishing achievable through CNC machining. After a part is 3D printed, CNC machining is employed to enhance tolerances, refine surface finishes, and achieve intricate geometries that might be challenging for 3D printing alone. This dual approach ensures the production of components with superior dimensional accuracy and surface quality, meeting the stringent requirements of various industries such as aerospace, automotive, and medical. At Vexma Technologies, we integrate advanced 3D printing and CNC machining technologies to deliver comprehensive solutions for your manufacturing needs. Our commitment to precision and innovation allows us to provide you with high-quality, customized parts that meet the most demanding specifications.
What is the effect on tool life surface finish and dimensional accuracy when applying roughing and finishing cuts?
Tool life is greatly shortened when used for both roughing and finishing thus affecting dimensional accuracy and surface finish badly as tool begin to wear off or get chipped, whereas, tool life gets longer when different tools are being used for roughing and finishing again dimensional accuracy and surface finish is affected but this time by achieving good results.
What are the advantages of cnc over conventional machining process?
Computer numerical control (CNC) machining has many benefits over manual machining. To begin, CNC machining is more reliable and accurate because it does not rely on physical labor. With its multi-axis capability, simultaneous operations, and automatic tool changes, it improves production efficiency. CNC machines provide for more freedom of design because they can easily create sophisticated geometries and patterns. CNC machining also facilitates quicker production turnarounds, lowers labor costs, and makes part reproduction less labor intensive. CNC machining has many advantages over traditional machining techniques, including greater accuracy, repeatability, and overall productivity, and the ability to work with a wide variety of materials.
