Why CNC Production is Essential
For production cnc machining parts there is necessary background otherwise alternative route can have option to do the same process, but it is necessary togo with it. Because bythis process youcanachievetolerances, fits, dimensions andsurfacefinish of thecode and standard either by production machining or welding / fabrication. But conventional fabrication and lathe machining cannot do the job in fast, smooth, precision and efficient way with delivery schedule of modern manufacturing timeline.
Following Youtube videos make better understanding of this process:
Small Batch CNC Processing
Discretestepmachiningis helpfulindoing of largescalemanufacturingproducts because inthis way you cansavelot of resources incnc machined products and expensive energy of product cost. Another advantage of this type of manufacturing cnc is that production time downs to minimum due to minus of some processes of production machining and auxiliary loading / unloading sequences. Everytime small batch CNC processing is not possible due to CNC milling products and reference datum surface of job, which can define job relative processes of topology.
High volume Production Machining
Large volume job have special need for its production cnc machining because every cnc machine cannot handle all dimension value of jobs in ease and fast manner. That is why every specification of CNC machine have its own parameters of bed, tool and table for manipulation of CNC production machinist otherwise low cost cnc machine can deal all the jobs without need of expensive one. In common example 16 m lathe and milling machine can handle production cnc machining without any help of extension bed, tools, lifter and fixtures.
Understanding CNC Production Machining
In order to understand the CNC production machining you need to have knowledge of cnc milling products, tools, shims, jogs and fixtures of different sizes / profile. Otherwise you have to hire expert machining job operator or company to complete your job without any machining defector out of tolerance. CNC machined products and its process have aspects of learning with following terms and terminologies:
What is CNC Production machining?
Production CNC machining is the process to make job dimensions, radius, morphology, thickness, hole and curve as per engineering drawing of job so that assembly can accept the same in final step. Another thing make you better understand of same process and that is operation of lathe and milling because these two terms can tell you that which final design of your product can work in better waysop that production cnc machining parts shall have the same at end of process.
Advantages of CNC Production Machining
CNC production machinist have many advantages to do the process because he has many parameters on controller to manipulate instead of one or two dimension cutting, shearing, shaperprocess to machine the job. Following are the few advantages of same:
1. Precision
Tolerance and precision of job by manufacturing cncis very easy to achieve because in this way uniform surface is present on job where you can remove the material and set the dimension as per counter part of assembly. In this way same job can make fit on that particular job to fit in it with the need of tolerance and precision, otherwise too much clearance can ruin the assembly working of engineering job.
Table.No.1 describes Precision.
Basic Dimension (mm) | Precision (mm) |
0.5 - 3 | +/- 0.05 |
3 - 6 | +/- 0.05 |
6 - 30 | +/- 0.1 |
30 - 120 | +/- 0.15 |
120 - 400 | +/- 0.2 |
400 - 1000 | +/- 0.3 |
1000 - 2000 | +/- 0.5 |
Table.No.1. General Precision of CNC Machining Process.
Information about precision machining parts isavailable here.
2. Consistency
Consistency of cnc made product is the key to success of manufacturing engineering because in this way you can complete the major task of your engineering drawing by just one step loading on cnc machine. Otherwise without any program of cnc machine manual lathe operation will give different result of milking, lathe and turning of your job.
3. Complex Designs
These design can have only one option to manufacture and that is by 3dmachining of same job because in this way CAM model of job can have its place inside the programming controller of CNXC machine. Otherwise to make complex design profile you have to use the different profile radius and jigs /fixtures to overcome the difficulties of manufacturing and tool access problems in machining.
4. Efficiency
Efficiency of this process is much more than the conventional method of manufacturing because in this way you can do the machining of job in quick and reliable way instead of slow method in conventional machines.
4 Key Factors for Successful CNC Production Process
There can be many cnc made products which have different quality with same profile job come from another cnc production companies, this is because of different factors need for cnc production process. Here are few factors:
MaterialSelection
Materials for shims, tools and inserts is much important thing for production of CNC machining process because it can decide that which cnc production companies are best for production of your job in less time.
CAD / CAM Software
Softwares can increase the production rate of cnc machining production because they can provide and even decide the machining programming and methodology to carryout the milling and lathe operation of job.
Figure.No.1 describes CAD / CAM inCNC Production machining.
Figure.No.1 CAD / CAM inCNC Machining. Tooling and Toolpath Optimization: Every job has some trajectories, radius profile, sharp edges and surface finish of drawing need but in this technique you can decide the sequence of machining operation with the help of Softwares so that one lathe and milling operation happen at sametime.
Figure.no.2. describes tool path optimization of CNC production machining.
Figure.No.2. Toolpath Optimization.
Machine Maintenance: If proper preventive maintenance of machine is the routine practice then of course it will not become out of order at time of crucial working and production time, this maintenance can also help in the planning of next maintenance schedule. General Specification of CNC production machining is present in Table.No.2.
Parameter | Values |
Maximum Path | 400-550 mm |
Maximum Electric Power | 40 KW |
Maximum Spindle Speed | 40,000 rpm |
Maximum Tool Length | 2500 mm |

12 Things You Should Know Before CNC Production Machining Project
To start CNC production machining it is much important to consider the few aspects, otherwise mess can happen during crucial machining stage of production.
Project Planning and Design
If one assembly has many parts then it is the project planning of operation which will decide that which operation is going to happen at first stage then soon, all jobs cannot be in production in parallel.
Machining MaterialSelection
Material of tool, shims and table is much important to decide the quality machining of jobs because in this way final product sketch become obvious for quality check and passing criteria.
CNC machine Tools and Equipment
Tungsten inserts are common parts of machining operation for CNC operation because they can machine almost every engineering material without any depression marks and cuts on the jobs and its surface.
Quality Requirements
Tolerances and precision is the important part of cnc production machining process because in this way assembly fits are present on the job parts and its functional design, otherwise bad quality can reject the complete heat number lot of same product.
Delivery Time
It is the important parameter of controlling the complete CNC production machining process because in this way you can decide that which job has ow delivery time and should be done on most urgent basis.
Cost Estimate
This estimate is always crucial process for any engineering product because whenever product comes at market then it is the cost at which manufacturing process has its completion. Thus machining cost is key factor for CNC production machining process due to milling, lathe and turning cost of the process and its relevant operations.
Preparation of Contracts
Contract need detail explanation of technical specification of machining including specifications, tolerance, precision and surface finish because this thing tells the cost estimation team to include the exact manufacturing prices at stage of contract.
QC
It is an important inspection stage by client or third party inspection team because this thing decides that either more work can happen at same qualification criteria or it needs more rework to pass the contract specification for passing of job.
Communication and Collaboration
Training of cnc machinist is always necessary to carryout good machining at mass production level otherwise one job has different angles to do the same at different alignments, thus training and collaboration with experienced setups can make quality of your product.
Intellectual Property Protection
Machining strategy sometime need research and development work then it is necessary to include the cost of same in final product of engineering, therefore it is necessary protect same research as per local intellectual property protection laws.
Risk Management
There are many risks which have involvement as per CNC machine operation because metallic chips and other loose clamping system can cause accident in operation, thus code and standard gives risk management plan for carrying out the same at workplace.
Figure.No.3 describes metallic chips risk assessment.
Figure.No.3. Metallic Chips Risk Assessment.
Sustainability
Once the machining strategy has its final stage after passing certain level of research and development work then it is obvious that if same strategy has its application next time in bath production then same are the results.

Best Practices for CNC Production Efficiency
There are manybest practices whichcan includethe CNCproductionmachiningprocess inefficient way of doing machining, here are few which can describe the same:
Design for CNC
Operation design of CNC production machining process is the best way to tackle with CNC machining operations because in this way every aspect of CNC machining is on the designer table to design and persecute the same in sequence.
Efficient Workholding
Efficient methodof doing work is thekeytosuccess inengineeringproduct manufacturing because in this way one can do the machining of same profile job with uni batch machining operation. C. Cutting Strategies:
Cutting operation in same strategy operation is the way to coverall the machining/ cutting operations in one batch, another aspect of this strategy is that raw material should be present in close tolerance to final machining surface so thatCNC needless work.
Quality Control and Inspection
Quality check always assure that only materials having final dimensions as per engineering drawing can goto next stage of assembly process otherwise re machining work is the need of inspection.
Case Studies: Real-Life Examples of CNC Production Success
Industry needs many steps CNC production machining processes because every job need togo for final dimensions without any milling and lathe operation that is why each industrial sector has its own design of CNC machine.
Robotics Industry
It need cnc milling products with tight tolerance and precision because they have application in places where fits are the requirement and need for automatic robotic operation. For example radiation or chemical dangerous gaseous operative robot work with tight tolerance of handling different equipments of flask,jars and buckets.
Aerospace Industry
Fine polishing and machining surface is the need for these types of products, consider an example of engine blade of aeroplane or drone which has special surface morphology to flow the air in particular direction.
Automotive Industry
Engine blocks and piston surface need special cnc machining surface of Alumnium because rough surface can damage the flow and engine efficiency of drive operation of vehicle in case of full engine power. Medical Devices Industry: Surgical items and routine operation tools need special machining surface of few microns roughness because rough surface tool can cause either damage in human organ or skin of sensitive body part.
Industrial Machinery
Industrial machinery of pump, rotors and chemical processing plants need special roughness of surface to counter the fluid flow turbulence effect and convert it into the laminar flow to make it in uniform working.
