Mastercam Mill Developments Target a Streamlined Manufacturing Process

Mastercam Mill offers expanded machining flexibility and an increased emphasis on speed and automation. Multiaxis features, 3D enhancements, and 2D high speed toolpaths combine with dozens of additional new enhancements in a software package intended to improve shop floor productivity.

Here are some of the significant highlights and new functionality in Mastercam Mill:

Multiaxis Improvements

Maintaining climb and conventional machining is crucial for surface finish and tool life. Controlling Climb and Conventional Cutting for Morph, Parallel, Unified, Project Curve, and Flow toolpaths now provide constant control of climb or conventional cutting even while in complex areas that would require use of both sides of the tool.

The new 3+2 Automatic Roughing toolpath automatically makes multiplane 3-axis toolpaths for roughing. Mastercam analyzes the model and stock, and then creates a roughing toolpath. Mastercam calculates the remaining stock and computes a new toolpath. This continues until only a defined amount of stock remains, and results are all contained within one toolpath.

Multiaxis Roughing has been enhanced and renamed to Multiaxis Pocketing and includes new options such as undercut roughing, wall finishing, and floor finishing. Multiaxis Pocketing provides greater control of the tool contract point and machining angle when using Accelerated Finishing® tools and ensures that you get the best possible motion.

The new Unified Multiaxis toolpath allows you to select multiple pieces of input geometry to generate the toolpath pattern. Then, using those geometry choices, the toolpath picks the best algorithm to calculate the path.

3D Enhancements
Mastercam’s 3D High Speed Blend toolpath includes many enhancements including the ability to keep created passes equidistant in 3D by adding cuts in steep areas, the capability to set the exact number of cutting passes, reverse cutting direction, confining curves to Tool tip or Tool contact point, as well as two new methods in the Cut method options. By applying Automatic and Custom Angles to Raster Toolpaths, Mastercam now automatically sets different angles to maximize the length of the cut pattern and/or minimize the connecting moves.

2D Enhancements
Advanced Drill, a new toolpath, is a customizable multi-segment drill cycle that is useful for spot drilling, deep hole drilling, and back spot facing. Each segment of the drill cycle can be defined in a table, and for each segment, you can customize any or all conditions. The new Chamfer drill uses tools with a tip angle and chamfers holes after calculating the correct depth based on the desired width or depth. It also allows you to select holes of different diameters or sizes—or that lie in different planes—and machine them in a single operation with a single tool.

Additional Improvements in Mastercam Mill that benefit efficiency include:

  • Improved toolpath processing time and surface accuracy for many Multiaxis toolpaths.
  • Toolpath Hole Definition has multiple new enhancements.
  • A new function, Check Tool Reach, can check your tool and holder against selected model geometry to view where the tool can and cannot reach.
  • In 2D Dynamic Mill, users are now able to skip pockets based on tool diameter or pocket size.
  • Contour enhancements such as additional Spring pass improvements and Profile ramping for Lead In/Out moves.
  • Setting separate feed rates for Entry and Exit linking moves.
  • And much more.

Related Glossary Terms

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

  • parallel


    Strip or block of precision-ground stock used to elevate a workpiece, while keeping it parallel to the worktable, to prevent cutter/table contact.

  • toolpath( cutter path)

    toolpath( cutter path)

    2-D or 3-D path generated by program code or a CAM system and followed by tool when machining a part.

  • undercut


    In numerical-control applications, a cut shorter than the programmed cut resulting after a command change in direction. Also a condition in generated gear teeth when any part of the fillet curve lies inside of a line drawn tangent to the working profile at its point of juncture with the fillet. Undercut may be deliberately introduced to facilitate finishing operations, as in preshaving.
