Port Expert

Facilitates toolpath generation for CNC cylinder head porting

Accurate & Efficient

Porting Motion

The Port Expert add-on for Mastercam creates accurate, efficient engine cylinder head porting toolpaths on port surface or solid data. Port Expert uses a lollipop tool, and has collision checks for the entire tool (shank, arbor, and holder).

The Port Expert toolpaths use three-axis machining as far into the port as possible, and then convert automatically to five-axis motion with minimum tilt. This prevents fishtails and inefficient reverse moves, and smoothly transitions where the toolpaths meet at the middle of the port.

Port Expert minimizes unnecessary motion at the machine, which results in a highly efficient toolpath with superior finish quality.

Create highly efficient roughing motion with Dynamic Motion™ toolpaths, or traditional offset-based roughing motion. Both methods are compatible with stock models, allowing the user to work within a partially-roughed opening with no air cuts.

Checks for collisions between the tool and workpiece. It automatically tilts the tool to eliminate collisions while keeping tool motion as efficient as possible.

Create the same efficient tool motion using one smooth single drive surface or with hundreds of reverse-engineered drive surfaces stitched together.

Programmers appreciate the simple user interface and intuitive approach to efficient toolpath generation with minimized, simultaneous 5-axis motion—in a fraction of the time it would take without Port Expert.

Supports 4-axis or 5-axis simultaneous motion for both roughing and finishing, so you can take advantage of the rigidity of a 4-axis setup or the reach of a 5-axis machine.

Regardless of the user’s choice of a 4-axis or 5-axis machine, Port Expert will minimize wasted machine movement by remaining in 3-axis mode for as long as possible.

MLC CAD Systems brings years of practical experience specific to various regions, manufacturing goals, and language requirements worldwide, to ensure that as a Mastercam user, you always have the support you need to get the most out of your CAD/CAM investment.
