An engineer who uses SOLIDWORKS every day and a setup technician moving into CNC programming bring different experience to a CAM course. The engineer may prefer to prepare machining beside the original model. The setup technician may first want to know which software local employers ask for. Those circumstances matter more than a general claim that either SolidCAM or Mastercam is the better package.
What job postings tell us
In the U.S. O*NET data for CNC tool programmers, Mastercam appears in 35% of unique job postings from 2025. SolidCAM is not among the six most frequently named software skills shown in the table. For someone seeking CNC programming work across a broad range of U.S. employers, that is a reason to consider Mastercam as a first system to learn.
The table does not give a percentage for SolidCAM or describe job markets outside the United States. It counts explicit skill mentions in postings assigned to an O*NET occupation. A shop can use a CAM system without naming it in an ad. Check openings in the target region and the requirements of specific employers before making a training decision.
SolidCAM alongside the CAD model
SolidCAM works inside SOLIDWORKS, Autodesk Inventor, and Solid Edge. Programmers can use the source model and define setups and operations within the same CAD environment. When the design changes, affected operations must be recalculated and checked. This workflow is useful when design and manufacturing teams regularly exchange revisions of a part.
Knowing SOLIDWORKS can make the model and assembly easier to navigate, but it does not replace machining skills. A finished program still depends on datum and tool selection, operation settings, toolpath checks, and a postprocessor for the actual machine. When a vacancy asks for SolidCAM, the employer generally needs experience with that full workflow, not just the ability to build a 3D model.
Mastercam across a varied machine fleet
Mastercam offers milling, turning, and mill-turn tools as well as geometry preparation tools. It can be learned as a separate CAM environment even when models arrive from different CAD systems. A shop with several kinds of machines can use it to maintain common programming practices, tool libraries, and postprocessors.
Its broad use does not mean a beginner needs every Mastercam feature. A sound starting point is an ordinary part: define the setup, create roughing and finishing operations, and check remaining stock and safe moves. Add multiaxis programming when it is part of the target jobs or the machines in the shop.
What to show an employer
Listing a CAM package on a resume says little about how independently someone can program. Describe the work instead: machine and part type, number of axes, material, operations, and any personal role in setup and first-part inspection. If examples can be shared, prepare a model and screenshots of setups, toolpaths, and simulation without disclosing a former employer's data.
One modest practice part is enough if the project shows a complete process. Explain the datums, stock, tools, and operation sequence. Show how collisions were checked and what would still need verification on the real machine after posting code. That discussion shows whether the candidate can prepare machining and check the result, regardless of which of the two CAM systems was used.
If a nearby shop uses SolidCAM and hires new programmers, learning its workflow is a sensible choice. If the goal is to widen a U.S. job search, the posting data favors Mastercam as the more frequently named skill. In either case, software training should go together with reading drawings, planning machining, and verifying NC programs.
