Quick Summary of BobCAD-CAM lathe software

BobCAD-CAM is a generic CAD/CAM software that can design and generate G-code for various CNC machines, including lathes.

It also has a software module committed to working with CNC lathes. You can activate lathe coordinates and switch between radius or diameter mode from the part settings.

The software also allows you to work with intersection curves, a helpful feature for turning jobs.

On its project tree manager, you can set the stock size and list out various operations performed on the stock as a workflow.

BobCAD-CAM allows you to set up the material type in the stock settings, but it won't calculate the feeds and speeds based on the selected material. You'll have to feed in that data to the software manually.

The software allows you to set the following turning jobs.

  • Rough
  • Finish
  • Groove
  • Thread
  • Drill
  • Cut off
  • Stock feed

After selecting the job, you can set the geometry from the design where the job is applied.

For each job, you can opt for separate moves or canned cycles. If your machine supports canned cycles, it's better to work with that as it keeps the program short.

It has a system and machine compensation feature available. Machine compensation is recommended because you can still use the generated toolpath if you change the tools.

BobCAD-CAM also allows you to add extra lead-in and lead-out length to the part where the cycle starts, so you don't have to draw the added geometry.

You can simulate the job within the software to preview the process. It allows you to move either the tool or part.

BobCAD-CAM only runs on PCs having a 64-bit Windows operating system. It requires at least 8GB of RAM, a 1GB dedicated graphics card, and a 2GHz processor.

You can try the software for free by downloading the demo. The developers have put up tutorial videos on YouTube for you to understand the software better.

CNC Lathe Programming for Turning

In CNC lathe programming software, the machinist formats a program different from traditional CNC programs. This is to match the unique configuration of CNC lathes. The rotary axis on CNC lathes separates them from other CNC machines and hence requires a unique piece of code having lathe-specific functions.

CNC lathes primarily come in two layouts, horizontal and vertical.

Horizontal lathes are the most common type of lathe, and they generally have a 2-axis or 3-axis setup.

On these lathes, the Z-axis governs the left-right, and the X-axis governs the front-back movement of the cutting tool.

Horizontal lathe (left), vertical turning center (right)
Horizontal lathe (left), vertical turning center (right)

On a vertical lathe, the Z-axis runs up-down, and the X-axis guides the left-right movement of the tool.

These machines require part programs different than other CNC machines, like routers, mills, etc., to machine the same part because of their difference in axis configuration.

Following is a list of lathe-specific functions used in G-code for programming CNC lathe.

G-CodeLathe-specific Function
X0Center of the part
Z0The face of the part
Anything you reduce from the part will be Z- (negative)
G50Used to limit spindle speed
G83Z-axis peck drilling cycle
G84Z-axis tapping cycle
G87X-axis peck drilling cycle
G88X-axis tapping cycle
G96Automated speed adjustment depending on stock size
G97Turns at a constant speed set by the operator
G71Rough turning canned cycle
G70Finish turning canned cycle
G72Facing cycle
G73Pattern repeating cycle
G75Peck grooving cycle
G76Screw thread cycle (single and double line)
G190Radius mode
G191Diameter mode
UIncremental for X
WIncremental for Z
Lathe-specific programming functions in G-code

A CNC machinist program the CNC lathe with these codes to perform different operations like roughing, facing, threading, tapping, reaming, finishing, etc.

You can program a CNC lathe with generic CNC software compatible with lathes or use dedicated software designed to work with lathes.

Final Thoughts

CNC lathe programming software saves you a lot of time by automating the machining process and helping you increase productivity.

Lathe-specific CNC software is available for CAD/CAM and control stages of running a CNC lathe.

These software programs let you import and work with designs made from other software.

Some of the things to consider while getting a CNC lathe programming software are as follows.

  • If it can perform both CAD and CAM operations, you can save money as you don't have to buy multiple software packages.
  • Check whether it shows a simulation of the generated toolpath. If it does, it helps you verify the toolpath for potential collisions.
  • Some lathe control software doesn't have multi-tool support, so if you have a lathe with live tools (e.g., VMC), it won't be compatible with the software.
  • Sometimes CNC software requires post-processors to work with different lathes. Check whether the software supports your machine. If not, ask the developers for a post-processor built for your machine. Most software comes with post processors for popular machines.
