In short: FLN Tutors gives CNC programming and machining assignment help and tutoring for mechanical, manufacturing and production engineering students. Tutors explain CNC machine types and axes, coordinate systems and work offsets, G-codes and M-codes, cutting speed, spindle speed and feed calculations, machining time, tool selection and compensation, canned cycles, CAM toolpaths and simulation step by step, with worked programs. Matched to a verified specialist who knows your course, your university's marking criteria, and your deadline.
Topics we cover
FLN offers one-to-one online CNC (Computer Numerical Control) tutoring with verified subject specialists. Sessions focus on calculations, design problems and the theory behind them, including G-Code Programming, CNC Turning, CNC Milling and Toolpath Generation, using your own course material, so you understand the subject and can apply it yourself.

CNC help is one-to-one support from a manufacturing engineer who explains how CNC machines are programmed and set up, and helps you write, check and simulate part programs. For 3D design before machining, see CATIA V5 help.

Milling with a 50 mm, 4-flute cutter at a cutting speed of 100 m/min and 0.1 mm feed per tooth, along a 200 mm cut.
| Step | Working | Result |
|---|---|---|
| Spindle speed | N = 1,000V ÷ (πD) = 100,000 ÷ (π × 50) | ≈ 637 rpm |
| Feed rate | F = N × teeth × feed per tooth = 637 × 4 × 0.1 | ≈ 255 mm/min |
| Machining time for 200 mm | 200 ÷ 255 | ≈ 0.78 min (about 47 s) |
Use the cutting data recommended by the tool maker for your material; these values are illustrative.
A short G-code program to cut a straight line and an arc.
| Line | Meaning |
|---|---|
| `G21 G90` | Millimetre units, absolute positioning |
| `M03 S1000` | Spindle on clockwise at 1,000 rpm |
| `G00 X0 Y0 Z5` | Rapid move to the start point above the part |
| `G01 Z-2 F100` | Feed down 2 mm into the material at 100 mm/min |
| `G01 X50 F200` | Straight cut to X50 at 200 mm/min |
| `G02 X70 Y20 R20` | Clockwise arc of radius 20 mm |
| `G00 Z5` then `M05` and `M30` | Retract, spindle off, end program |
Tutors match your level, syllabus and exam board, from school to PhD.

Most lost marks come from unsafe programs and wrong cutting data.
| Mark-loser | What to do instead |
|---|---|
| Rapid moves into the part | Retract to a safe height before G00 moves |
| Mixing absolute and incremental | State G90 or G91 clearly |
| Wrong spindle speed formula | Use N = 1,000V ÷ πD with D in mm |
| No tool compensation | Apply tool length and radius offsets |
| Programs not simulated | Simulate before running on a machine |
| Missing program end codes | End with spindle off and M30 |
CNC machining and programming is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Programming tasks | Correct, safe part programs |
| Practical exams | Setting up and running machines |
| Projects | Parts made from CAD to CNC |
| Reports | Process plans, cutting data and inspection |
| Exams | Codes, calculations and concepts |
CNC programmers use these tools.
| Tool | What it is used for |
|---|---|
| CNC simulators | Checking programs safely |
| CAM software such as Fusion 360, Mastercam or SolidCAM | Toolpath generation |
| Tool maker cutting data | Speeds and feeds |
| Vernier calipers and micrometers | Inspection |
| Controller manuals (Fanuc, Siemens) | Controller-specific codes |
CNC machining and programming is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where cnc machining and programming is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | Manufacturing and mechanical engineering degrees and apprenticeships | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Manufacturing technology and machining programmes | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Engineering and TAFE machining courses | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Machining and manufacturing programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | ITI, diploma and B.Tech/BE mechanical and production engineering CNC labs | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of cnc machining and programming help depends on the program size and your deadline. A short program check costs less than a full CAM project. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Student reviews
Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors help you write, check and explain CNC programs, within your course's rules.
Computer numerical control: machines controlled by programmed instructions to cut parts precisely.
The programming language that tells CNC machines how to move.
G00 is a rapid move; G01 is a controlled straight-line feed move.
They cut clockwise and anticlockwise arcs.
G90 uses absolute coordinates; G91 uses incremental coordinates.
Miscellaneous codes that control functions such as the spindle, coolant and program end.
N = 1,000V ÷ (πD), with cutting speed V in m/min and diameter D in mm.
Feed rate = spindle speed × number of teeth × feed per tooth.
A stored position, such as G54, that sets the part's zero point on the machine.
Using G41 or G42 so the machine offsets the toolpath by the tool radius.
A pre-programmed routine, such as G81 for drilling, that simplifies repetitive operations.
Computer-aided manufacturing software that generates toolpaths and G-code from a CAD model.
Yes. Tutors cover Fanuc-style programming and its common codes.
The codes are logical; practice with simple parts builds confidence.
Tutors work from your course text, such as Smid's CNC Programming Handbook.
Often, yes, for short program checks, depending on tutor availability.
Yes. Tutors help from modelling through toolpaths to simulation.
Yes. Tutoring, worked examples and feedback are a normal part of learning. You should use the explanations to understand the method and submit your own work in line with your school's or university's academic integrity rules. See our academic integrity policy.
Yes. Your files and details are used only to help you and are not shared with your school or university. See our privacy policy.
