Mastercam post processor development

Posts that run right the first time.

D&R Precision writes and fixes Mastercam posts for the machines you actually run, from three-axis mills to five-axis. You get clean G-code at the control, with no hand edits at the machine.

Everything between the toolpath and the control

New post development

A post written from scratch for your machine and control, built around how your shop programs and what your operators expect to see.

Post modification and fixes

Wrong tool change, bad arc output, missing cycle, a header the machine rejects. Send the post and the problem and it gets corrected at source.

Five-axis and multi-axis

Tool-centre-point control, tilted work planes, table-table, head-table and head-head kinematics, with safe rotary moves and sensible retracts.

Mill-turn and multi-channel

Taken on case by case. Send the machine, control and a proven sample program, and you will get a straight answer on scope before any work starts.

Machine and control definitions

Machine Definition and Control Definition files set up to match the real machine, so simulation and the post agree with each other.

Documentation and handover

Every post ships with notes on its options, misc values and limits, so your programmers know what it does and can switch features on and off.

Worked example

Polar milling for large parts

Big parts can push a machine to the limits of its travel. This post includes a polar milling option, switched on from the operation's misc values, so the rotary axis helps keep the cut inside the machine's reach.

Controls

Written for the control on your machine

Every control reads G-code a little differently. Posts are built to the dialect, cycles and limits of the control you run, not to a generic template.

How it works

From brief to a post you can trust

STEP 1

Brief

Machine make and model, control, axis layout, and a sample of the G-code you want to see. Existing posts and good proven programs help most.

STEP 2

Build

The post and its definitions are written to match the machine, then run against your own test parts in Mastercam.

STEP 3

Prove

The output is checked line by line against the control's rules and your sample code, then dry-run on the machine before real material is cut.

STEP 4

Hand over

You receive the post, the Machine and Control Definitions and a short guide to the options, ready to install and use.

What lands in your folder

Plain, editable files that belong to you. Your team can open the post, read it and change it later without needing to come back.
